Brief Introduction to MTP MPO Fiber Accessories

MTP MPO fiber accessories mainly include fiber optic connectors and fiber optic adapters. An optical fiber connector is a flexible device that connects fiber cables requiring a quick connection and disconnection. Optical fibers terminate fiber-optic connections to fiber equipment or join two fiber connections without splicing. Fiber connectors ensure stable connections, as they ensure the fiber ends are optically smooth and the end-to-end positions are properly aligned. Fiber optic adapters (also known as fiber couplers, fiber adapter ) are designed to connect two optical cables together. They have a single fiber connector (simplex), dual fiber connector (duplex) or sometimes four fiber connector (quad) versions.

Common Types of MTP MPO Fiber Accessories

Fiber Optic Connector

Types of Fiber Optic Connector

Lucent Connectors (LC)

Lucent Connectors, typically known as LC connectors. They have some of the smallest ferrules at just 1.25mm thick, making them a small-form-factor fiber connector type. Their size, square shape, and duplex header design make them ideal for heavily populated patch panels and cabinets where packing in as many connections as possible into a tight space is the goal. It’s one of the most commonly used fiber optic connections today and works with both multimode and single-mode cables. Cables fitted with LC connectors are fairly difficult to remove once plugged in, making them one of the more sturdy cable connector standards.

Standard Connectors (SC)

SC connectors were colloquially known as Standard Connectors or SC Connectors. They’re a square-shaped, duplex connector that uses a 2.5mm ferrule and has a push-pull mechanism to latch them in place. This makes them more robust than other connectors, like ST connectors, so the signal won’t be interrupted if the cable is pulled. This is an older connection that is slowly being replaced but has been a standard for long enough that it has seen extensive usage in networks all over the world. While its square shape does make it useful for fitting into smaller spaces, more modern, leaner connections like LC connectors, have proved more effective and space-saving, so are seeing greater use in newer network rollouts.

ST Connectors

ST connectors were one of the first fiber connector types to see widespread adoption in fiber optic networks all over the world. Straight Tip (ST) design has a 2.5mm ferrule, the same as SC connectors, and can be used interchangeably with that alternative connector type when using a hybrid adapter. It features a spring-loaded, half-turn bayonet-style lock that makes it quick and easy to attach and detach, all whilst providing additional security against accidental disconnects. It’s not foolproof, with other fiber connector types offering a more robust connection, but it’s still useful. Typically used with multimode fiber optic cables, ST connectors see a lot of usage in legacy networks, although they are slowly being replaced by newer cables.

Ferrule Core Connectors (FC)

FC connectors are so named because they were the first to be built with a ceramic ferrule with a stainless steel screw mechanism for attachment. This is in stark contrast to the plastic bodies of most other fiber connector types, like SC, and LC connections. FC connectors are designed to provide a much more robust connection that is almost immune to accidental removal, thereby guaranteeing there won’t be any interruptions in the data. The keyed screw connection with FC connectors does mean that installing and uninstalling them takes extra effort. Mostly used with single mode fiber optic cables, FC connectors are commonly used in networks designed to transmit consistent information, such as video streams, where any drop in the data connection would cause an immediate and obvious interruption of the data. They are, however, seeing reduced use in newer networks, with administrators preferring the ease of use with LC and SC connectors.

Multi-Position Connectors (MPO)

MPO connectors, sometimes marketed interchangeably with MTP connectors, are simplex fiber connector types with a push/pull latch system that locks them into place. While MTP is largely a branding choice rather than a distinct connector type, the connectors were designed with higher-performance networks in mind, while MPO connectors are more commonly marketed toward less demanding applications. Both fiber connector types work with single mode and multimode cables - the ferrule is slightly angled on single mode cables - though they see the most usage in high bandwidth multimode cables, due to the way the connector combines up to 24 glass fibers within a single rectangular ferrule. MPO/MTP connectors are particularly complicated to use due to potential issues with polarity arising from misconfigured cabling. Network administrators need to make sure they use the right configuration of cables to avoid any problems with signal transmission.

Advantages of Fiber Optic Connector

Fiber optical connectors can realize the conversion between different interfaces such as FC, SC, ST, LC, MTRJ, MPO and E2000. They are widely used in optical fiber distribution frames (ODFs) Instruments, providing superior, stable and reliable performance. Compared to copper cables, fiber connector types are incredibly varied. Where copper twisted pairs tend to terminate with an RJ45 plug, fiber optic connectors come in all sorts of shapes and sizes, with all manner of different use cases in mind.

Fiber Optic Adapter

Types of Fiber Optic Adapter

FC Fiber Optic Adapter

FC is an acronym for FERRULE CONNECTOR, indicating that its external reinforcement is the use of the metal sleeve, fastening the way for the buckle. The earliest, FC type connector, the docking end of the ceramic pin. Such connectors are simple in structure, easy to operate and easy to manufacture. However, the fiber end face is more sensitive to dust, and it is easy to produce Fresnel reflection and it is difficult to improve the return loss performance. Later, this type of connector has been improved, the use of docking the spherical end of the pin (PC), while the external structure has not changed, making the insertion loss and return loss performance has been greatly improved.

SC Fiber Optic Adapter

The shell is rectangular, the pin and the coupling sleeve used in the structure of the same size and FC type. One end of the pin to use more PC or APC grinding method; the casting method is the use of plug pin type, without rotation. Such connectors are inexpensive, easy to plug and unplug, low insertion loss variations, high compressive strength, and high installation density.

DIN47256 Fiber Optic Adapter

The pins and coupling sleeves used in this connector are the same size as the FC type and the PC process is used for the end face processing. Compared with the FC type connector, the structure is more complex, and the internal metal structure has a control pressure spring to prevent the end face from being damaged due to the excessive insertion pressure. In addition, this connector has higher mechanical accuracy and therefore smaller insertion loss values.

LC Fiber Optic Adapter

The LC connector is made of convenient modular jack (RJ) latch mechanism. The pins and sleeves used are half the sizes used for normal SC, FC, etc., at 1.25mm. This will increase the density of fiber optic connectors in fiber distribution frames. Currently, in the single-mode SFF, LC type of connector has actually occupied the dominant position, the application of multi-mode is also growing rapidly.

MTP/MPO Fiber Optic Adapters

MPO / MTP adapter is connected using an MPO / MTP Precise connection of two guide holes with a diameter of 0.7mm and a guide pin on the left and right ends of the ferrule. MPO / MTP adapters are widely used in communication system base stations, optical fiber distribution frames (ODFs) in building rooms, MPO / MTP cassette module, and various test instruments.

Advantages of Fiber Optic Adapter

The optical fibers are connected by an adapter through its internal open bushing to ensure the maximum connection between the optical connectors. In order to be fixed in a variety of panels, the industry also designed a variety of finely fixed flange. Transformable optical adapters are available with fiber optic connectors of different interface types on both ends and provide a connection between APC faceplates. Duplex or multi-adapter adapts to increase installation density and save space.

MPO Connector Applications

MPO Connectors have been used in duplex 10 Gig fiber applications throughout the data center for several years as a way to deploy preterminated plug and play backbone cables between switches that take up less pathway space and ease cable management while offering faster deployment. In these 10 Gig applications, 12-fiber or 24-fiber trunk cables with MPO connectors on both end form the permanent backbone link and are then transitioned to duplex fiber connectors at patch panels via either MPO-to-LC cassettes or MPO-to-LC hybrid patch cords.

As the need for bandwidth speeds pushed beyond 10 Gig, the MPO connector became the de facto interface for higher speed switch-to-switch backbone data center applications using parallel optics. For example, 40 Gig and 100 Gig applications (40GBASE-SR4 and 100GBASE-SR4) over multimode fiber use 8 fibers with 4 transmitting at either 10 Gbps or 25 Gbps and 4 receiving at either 10 Gbps or 25 Gbps. These common data center applications require an 8- or 12-fiber MPO connector (only 8 of the 12 fibers are used when using 12-fiber MPOs). Looking ahead, standards bodies are anticipating even higher speeds of 200 and 400 Gig also being supported by MPO connectors and parallel optics. The MPO connector interface is therefore here to stay.

Fiber Optic Connectors Selection Guide

Before choosing MPO fiber connectors, you should know know what factors you want to consider. The selection connector can directly affect your installation quality and cost.

Fiber Optic Cables Type

There are two basic types of fiber optic cables: single mode and multimode. Is your fiber optic cable single mode or multimode? Single mode fiber optic cable allows for one light mode to propaganda at one time, while multimode means that multiple light modes can pass through the fiber. The multimode also features a larger central core than the single mode to allow for different rays of light. You can identify whether the cable is single mode or multimode by the jacket color. In general, the single-mode cable comes with a yellow or blue jacket and a multimode cable feature an orange or green cover. Fiber connectors also come in single mode and multimode. And single mode fiber connectors usually have blue or green covers, while multimode connectors feature beige covers. But different manufacturers may have different color choices, so you’d better verify it from the suppliers before buying. With the development of technology, many fiber connectors such as FC and LC are compatible with both single mode and multimode fibers.

Polish Type

Connectors are available with differently polished endfaces, which impact the connector’s level of return loss (back reflection). Single mode connectors are available either as a UPC (Ultra Physical Contact) or an APC (Angled Physical Contact/Angled Polish Connector). UPC connectors are most commonly installed. These connectors have a slightly domed endface. For identification, single mode UPC connectors are colored blue. APC connectors feature an 8 degree angle at the endface. This decreases their return loss. However, APC connectors have very specific applications (GPON, FTTx, etc.) and used only when equipment requires them. APC connectors are commonly used by service providers, or for very long distance transmission. For identification, APC connectors are colored green. Due to the angle of an APC connector, it cannot be mated to a UPC connector. These connector types are not interchangeable, so it is very important to verify whether your installation requires UPC or APC connectors.

Color Coding

Connectors are color-coded to identify multimode connectors and single mode APC or single mode UPC connectors. Note that color coding conventions vary by manufacturer, so always make sure to double check your cables and connectors. The general guidelines are.

Aqua: 50/125 Multimode (OM3/OM4, also compatible with OM2 fibers)

Blue: Single mode UPC

Green: Single mode APC

Beige, although this is variable: 62.5/125 Multimode (OM1)

Black: 50/125 Multimode OM2 (varies by manufacturer)

Termination Types

There are many types of connector terminations. Should you choose epoxy and polish termination or quick termination connectors? It depends on the installation quality and cost. Let’s take a look at some of your options.

Epoxy and Polish Termination: This traditional termination type is chosen by most people. The ferrule is bonded with epoxy and the end is polished with a thin film. This kind of termination takes longer to install but offers high quality, low cost, and excellent stability.

Pre-Polished Termination: This type of connector features a pre-polished fiber end inside the connector body and you only need to strip your fiber, and then cleave and insert it into the connector body. It is a quick termination but can be a bit expensive.

Anaerobic Termination: In anaerobic termination, the fiber connector features a quick-setting glue. Because the glue can not withstand water or high temperatures, it is only suitable for indoor fiber optical applications.

MTP vs MPO Connector: What is the Difference?

Pin Clamp

MPO connectors typically have plastic pin clamps, which can easily break pins with constant cable mating, whereas MTP connectors have a metal pin clamp to ensure a tight clasp on the pins and reduce any unintended breakage when mating connectors. The oval spring is utilized in the MTP connector to increase the distance between the fiber ribbon and the spring, which can prevent the fiber ribbon from damage during insertion. The MTP cable design, incorporating a recessed pin clamp and oval spring, ensures a tight spring seat and wider clearance between the spring and the ribbon cable, reducing the possibility of MTP cable breakage.

Removable Outer Housing

The second significant difference is the connector housing. MTP uses the removable connector housing, while the generic MPO does not guarantee a removable housing. The removable housing provides some advantages.

Easily Change the gender after the assembly or even in the field
After assembly, use an interferometric scanner to scan the ferrule

Guide Pins

MTP and MPO connectors use different guide Pins. The MPO uses chamfer-shaped guide pins, while the MTP uses an elliptical stainless steel guide pins. Compared to MPO, these MTP elliptical-shaped pins can ensure better guidance. The decreased amount of debris on the end surface of the pupil or the wrap so that the MTP optical fiber connector is more long-lasting to maintain high-performance transmission.

Floating Ferrule

The fourth difference between MTP and MPO is the Floating Ferrule. MPO connectors usually use MT Ferrule, while MTP connectors upgrade it to floating ferrule. The Floating Ferrule is a unique feature of MTP connectors that offers significant advantages over traditional connectors. The floating ferrule is used to improve mechanical performance in an MTP cable. The ferrule can float within to maintain physical contact across a mated pair under applied load. That allows two mated ferrules to maintain physical contact under an applied load, resulting in reduced insertion loss and improved alignment. Moreover, the floating ferrule feature also helps to prevent dust and other debris from accumulating on the end surface of the ferrule, which could otherwise cause damage or reduce the connector’s performance. Overall, the floating ferrule feature is one of the critical advantages of MTP connectors, making them the preferred choice for high-density cabling systems in data centers.

Insertion-loss

As previously discussed, the differences between MPO and MTP connectors lead to different insertion loss levels. MTP connectors tend to have lower insertion loss than MPO connectors. For instance, the MTP multimode connector provides 0.6dB max insertion loss, while the MPO provides 0.75dB max insertion loss. It’s essential to note that while the difference in insertion loss between the MTP and MPO connectors may seem small, it can make a significant difference in high-speed and long-distance applications. The lower the insertion loss, the less signal degradation, and the better the overall system performance.

Frequently Asked Questions

Q: What is wide band multimode fiber and how is it used?

A: WBMMF is a relatively new fiber medium specified in ANSI/TIA-492AAAE and given the designation of OM5 multimode fiber by ISO/IEC and TIA. This 50/125 µm multimode laser optimized fiber was originally developed to support Short Wavelength Division Multiplexing (SWDM) and supports 4 wavelengths of 25Gb/s transmission for an aggregated 100 Gb/s transmission on a duplex LC link, a popular and familiar interface in the data center. WBMMF supports four wavelengths between 850 nm and 953 nm, using multimode optics. WBMMF was designed for use in data centers.

Q: How does WDM technology differ from parallel optics?

A: Whereas Wavelength Division Multiplexing (WDM) utilizes a single fiber, parallel optics uses multiple fibers and lanes at various transmission rates. At the 25G transmission rate and at 100 meters, for example, IEEE’s 400 Gb/s migration path requires 16 lanes (16 MMFs to transmit and 16 to receive) for a total of 32 multimode fibers. This parallel configuration launched new 16-fiber and dual-row 32-fiber MPO connectors for which TIA recently published a standard. At 500 meters for SMF, four lanes / 8 fibers total are required by the IEEE for 400 Gb/s. Currently, the IEEE P802.3cd is defining standards for 50 Gb/s, as well as next generation 100 Gb/s and 200 Gb/s Ethernet.

Q: Will WDM/SWDM ultimately replace parallel fiber optic solutions?

A: The consensus is that both solutions will coexist and depend upon specific data center network goals and applications. Employing parallel fiber solutions are currently necessary to transition between speeds, so that breakout capability is essential.

Q: What’s the difference between Tier 1 and Tier 2 Testing?

A: Tier 1 testing looks at loss, length and polarity. While Tier 1 fiber optic tests can identify problems in terms of pass or fail, they cannot determine the root cause or location of the problem. Tier 2 fiber optic testing is used to pinpoint root-cause locations and the amount of loss and optical return loss (ORL) from each problem contributor and is performed selectively in addition to Tier 1 testing under specific conditions and situations. Tier 2 fiber testing provides a deeper level of link visibility unlike any other fiber infrastructure tests. The optical time-domain reflectometer (OTDR) is used to perform Tier 2 fiber optic testing.

Q: What is an MPO connector?

A: MPO stands for ‘Multi-Fiber Push On’. It is a multi-fiber connector (a single connector that houses multiple fiber counts) defined by IEC-61754-7 and TIA-604-5-D. Compared with the traditional SC or LC fiber connector, the MPO connector provides much higher fiber density and reduces space. Therefore, it is a high-density fiber optic connector used in modern data center cabling systems. The MPO features a rectangular plastic housing that holds up to 12, 16, or 24 fibers arranged in a row, two guide pins or holes in the connector, and a push-pull mechanism that allows quick installation and removal.

Q: Is the MTP connector also an MPO connector?

A: Yes. The MTP connector is a high-performance MPO connector with improved mechanical and optical performance. It should be noted that all MTPs are MPOs, but not all MPOs are MTPs. An MTP connector is 100% interchangeable with its generic MPO-style product. However, in high-performance applications, an MPO connector is not operationally equal to an MTP.

Q: Since MTP cable performance is better, should I always choose it?

A: Only sometimes necessary. When selecting between them, it’s essential to consider your specific application requirements and budget. For instance, the MPO cable may be a more cost-effective option if you’re working with a limited budget. Additionally, suppose your application doesn’t require high-speed or long-distance transmission. In that case, the difference in insertion loss between the two connectors may not be significant enough to warrant the extra cost of the MTP cable. However, the MTP cable would be the better choice if you’re working on a high-speed and long-distance transmission application that requires low insertion loss. So consider all your specific application requirements, budget, and performance needs before deciding.

Q: How to clean MPO connectors?

A: The method for cleaning MPO connectors is to inspect, clean, and reinspect. Inspect - Always inspect the connector first. You don’t need to clean a connector if it’s already clean, as cleaning it might actually make it dirty. This is especially true for MPO connectors, which are highly sensitive. For example, for an MPO-24, dirt from the first row could potentially migrate to the second row while cleaning. Make sure to inspect both mating connectors, as residue from a dirty connector will transfer to a perfectly clean connector once they mate.

Q: What are MPO connectors used for?

A: MPO stands for Multi-Fiber Push On. This connector is commonly used to terminate multi-fiber ribbon connections in indoor environments. It conforms to IEC-61754-7; EIA/TIA-604-5 (FOCIS 5) standards.

Q: What is the difference between male and female MPO connectors?

A: MPO connectors can either be male or female, often referred to as the gender type of a connector. The male connector has pins, whereas the female connector has no pins.

Q: What minimum size is the MPO connector?

A: MPO Connector, with its familiar push-on/pull-off insertion release mechanism, provides consistent and repeatable interconnections with up to 48 fibers in a 0.7” x 0.4” mini-mum footprint.

Q: What test solutions are available for MPO connections?

A: With all fiber networks, there are essential tests that technicians perform for either certification or troubleshooting purposes, such as: fiber inspection, length and loss testing, or advanced OTDR testing to identify specific events throughout the link. While this is no different for MPO connectors, it becomes increasingly complex as the connector interfaces on legacy test instruments have single-fiber connectors.

Q: What MPO connectors are and how they are used in fiber networks?

A: While MPO connectors have been around for many years, they have historically been utilized in places where most technicians don’t have to interact with them very much, if at all. This is rapidly changing as network capacity demands increase. As a result, the use of multi-fiber connectivity has become the preferred medium for the latest network architecture designs. They are no longer used only behind the scenes but are now extended all the way to patch panels, switches and servers, where they are front and center for every technician to deal with.

Q: What is polarity of MPO connector?

A: A transmit signal from any type of active equipment will be directed to the receive port of a second piece of active equipment and vice versa. Polarity is the term used in the TIA-568 standard to explain how to make sure each transmitter is correctly connected to a receiver on the other end of a multi-fiber cable. Once the component is connected to the wrong polarity, the transmission process will be unable to go on.

Q: MTP or MPO connectors: what is the difference?

A: MPO or MTP terminated cables are widely used in high density cabling environments like data centers. Traditional, tight-buffered multi-fiber cable needs to have each fiber individually terminated by a skilled technician. MPO cable which carries multiple fibers, comes pre-terminated. Factory terminated MPO / MTP connectors commonly have either 12 fiber or 24 fiber array. Compared with conventional MPO connectors, MTP fiber connectors are enhanced in both optical and mechanical properties. The MTP connector fully complies with the professional standards of all MPO connectors. The MPO connector is and MTP connector that can be paired with each other, which means that it is possible to replace an MPO connector with an MTP connector for better performance. Most MPO connectors with older designs are limited in performance and cannot provide the same high performance as MTP connectors.
