Fiber-Optic Based Ethernet Cable standards 1 VIII  Wireless Networking

Once a fiber-optic cable termination has been made, it must be connected to the end-point device. There are a number of different types of fiber-optic connectors.

While fiber-optics has not found common use in everyday life, fiber-optics has been in use long enough to have a legacy connector. That connector type is known as the SMA connector. The SMA connector features a threaded cap and housing. It has been replaced in large part by the ST connector.

The ST connector is the most common connector in use today. The ST is popular both in buildings and finds use in the field. The bayonet mount uses a keyed coupling and utilizes a push/twist installation that prevents over-tighting and subsequent damage of the fiber-optic end. The ST connector is used with both SingleMode and MultiMode fiber. The shape and connection method is similar to a BNC connector (as used for 10Base2 cable connections).

One of the newest connectors in the fiber-optic world is the SC connect. The SC connector is a push-pull connector and while commonly used with SingleMode fiber, there are versions that also work for MultiMode fiber as well. The SC connector can be found as a single connector designed to hold a pair of fiber optic strands and is known as the SC Duplex connector.
