**Introduction
In the world of fiber optic technology, MPO and MT ferrules are two of the most commonly used terms. These ferrules are used in the production of fiber optic cables and connectors. The MPO and MT ferrules may seem similar; however, they have notable differences in their structure and use.
In this article, we will explore the major differences between MPO and MT ferrules. We will also discuss the structure of these ferrules, their applications, and their advantages and limitations.
**Structure
MPO and MT ferrules are both cylindrical parts made of ceramic or plastic material that serves as a mechanical connector for fiber optic cables. The ferrules act as the end faces of the connectors and are designed to ensure proper alignment of the optical fibers. While both ferrules serve similar purposes, they have differing structural designs.
**MPO Ferrules
MPO is an acronym for multi-fiber push-on/pull-off. As the name suggests, it is a multi-fiber connector with a push-pull mechanism that enables fast and easy connections.
MPO ferrules are designed with a rectangular ferrule shape and a flat end-face. The ferrule has a clamping mechanism that aligns the fibers by compressing them against the end-face. It also has a guide pin used to ensure proper alignment of the connector.
**MT Ferrules
MT is an acronym for mechanical transfer. This ferrule was designed as a solution for high-density fiber optic installations. The MT ferrule has a circular shape and a convex end-face. Its end-face is polished to form a precise curvature that maximizes light transmission and reduces signal loss.
MT ferrules have a spring-loaded mechanism that aligns the optical fibers into position. The MT ferrule also has a guide pin that ensures a precise alignment of the connector.
**Applications
The MPO and MT ferrules have different applications and are used for different purposes.
**MPO Applications
MPO connectors are commonly used in data centers and telecommunications systems where a high amount of data needs to be transmitted quickly. MPO connectors can carry up to 12 fibers, making them ideal for high-density installations.
**MT Applications
MT ferrules, on the other hand, are used in high-speed computing and data storage systems. MT ferrules are renowned for their high precision and low insertion loss, making them ideal for applications where signal loss needs to be minimized.
MT ferrules are also used in military and aerospace applications, where vibration and shock resistance are essential.
**Advantages and Limitations
MPO and MT ferrules both have their unique advantages and limitations.
**MPO Advantages
One of the significant advantages of MPO connectors is their push-pull mechanism, which enables fast and easy connectivity. MPO connectors are also available in different fiber counts, making them ideal for high-density installations.
However, because of their clamping mechanism, MPO connectors are sensitive to dust and debris, which can cause an increase in insertion loss.
**MT Advantages
MT ferrules have a circular shape and a convex end-face, which ensures reduced signal loss. They are also renowned for their high precision and low insertion loss, making them ideal for applications that require a high level of accuracy and signal protection.
MT ferrules also have a higher vibration and shock resistance than MPO ferrules, making them ideal for military and aerospace applications.
However, MT ferrules can be difficult to clean, which can lead to contamination and higher insertion loss.
**Conclusion
In conclusion, while the MPO and MT ferrules may seem similar, they have notable differences regarding their structure, applications, advantages, and limitations.
MPO connectors have a rectangular ferrule shape, while MT connectors have a circular shape and a convex end-face.
MPO connectors are commonly used in data centers and telecommunications systems, while MT connectors are used in high-speed computing and data storage systems, as well as military and aerospace applications.
MPO connectors have a push-pull mechanism that enables fast connectivity, while MT connectors have a high level of precision and signal protection.
Overall, the choice of connector depends on the specific application and its requirements, including the number of fibers, environmental conditions, and signal loss tolerance.
