Fiber optic jumpers are accessories used to connect devices on telecommunications networks (such as switches, routers, hubs, etc.), or other related communication links. In modern society, people are increasingly relying on electronic products in their work, but sometimes this thing may not be suitable for you to use on your own. Therefore, what I want to share with you today is the interface type of fiber optic jumpers.
There are currently many specifications and styles of fiber optic jumpers on the market.
Fiber optic interfaces are physical interfaces used to connect fiber optic cables. The principle is to use light to enter the light sparse medium from the light dense medium, resulting in total reflection. There are usually several types, such as SC, LC, ST, FC, etc.
SC interface for fiber optic jumpers: The SC interface is a connector used to connect GBIC optical modules. Its shell is rectangular and fastened using a plug and pull pin latch type without rotation. The SC interface can be directly plugged in and out, making it convenient to use. The SC interface is made of engineering plastic, which is resistant to high temperature and not easily oxidized. The SC interface of fiber optic jumpers is more commonly used on routers.
LC interface for fiber optic jumpers: The LC interface is similar to the SC interface, but smaller than the SC connector. LC connectors are mostly used to connect SFP fiber optic modules and are made using a modular jack (RJ) latch mechanism that is easy to operate. The commonly used LC jumpers are used to connect optical fibers and optical modules, so they are generally LC-SC or LC-FC, and most of them are used in pairs, with few single LC jumpers appearing. This type of interface is commonly used in routers.
ST interface for fiber optic jumpers: The ST connector shell is circular, with a bayonet, connected to the ST coupler, and needs to be rotated approximately 90 ° during use. Tightly connected and not easily detached. Commonly used in fiber optic distribution frames.
FC interface for fiber optic jumpers: The FC connector is similar to the ST connector and has a circular shape, but the FC connector has threads inside and is connected to the FC coupler through rotation. The FC interface of fiber optic jumpers is firmly connected, dustproof, and commonly used in distribution frames.
