When installing a fiber, you often must choose the most efficient fiber connector types for the purpose at hand. A fiber connection is also known as a termination and allows you to swiftly join and disconnect fiber lines. Many fiber connector types have a spring-loaded connection to ensure that there is a continuous force connecting the two fibers, guaranteeing a solid clean connection for the pulse to flow through. These spring-loaded connections additionally support their weight by preventing air gaps between the connectors. An air gap quickly obstructs light transmission from fiber to fiber.

SC fiber connector

The 12 SC Cable was designed to immediately replace ST connectors and has since become one of the most prevalent fiber connectors in the world. This SC type, like the ST connector, has a 2.5mm ferrule.

Advantages

The SC connection is what is known as a non-optical detach connector. This phrase refers to the fact that after the connection is mounted, any pushing or tugging on the jacket of the cable will not cause the ferrule to disconnect, which is a common issue with ST-type connectors. This assures that the transmission will not be interrupted. When ST connections are pushed back, the spring mechanism might cause the fibers to smash together. An SC connection can help with these issues.

The square shape of these connectors allows for a more compact construction, allowing more of them to be put in a smaller space. When the pull and twist connections just do not fit, the SC connector comes in handy.SC connections are ideal for data communications and telecommunications.

LC Fiber Connector Types

Lucent Technologies invented the LC connectors, thus the name. This is part of the small form factor (SFF) connection family. These SFF connections were first developed to meet a demand for high-fiber count applications. In certain configurations, dozens of connections are plugged in, which makes life a lot simpler. The LC connection features a 1.2mm ferrule and a footprint that is almost half the size of the other connectors we have studied. The non-optical disconnect is the same as the one shared by the 12 SC Cable and FC.

If you need to move from a SC, ST, or FC connection, there are certain tools and adapters available. Another advantage of this connector is that the LC duplex connections share the same footprint as RJ45 connectors.

Advantages

Using a clip, you can convert these instruments from simplex to duplex connectors. They are low-loss connections that are also pull-resistant. 12 LC Cable connections may be swiftly terminated, and there are several techniques for doing so. The SFF design makes this the ideal connection for high-density applications, making it the preferred connection for networking and transceivers. Many fiber connector types have a spring-loaded connection to ensure that there is a continuous force connecting the two fibers, guaranteeing a solid clean connection for the pulse to flow through.
