6.5 Connectors
6.5.1 Connector Types
In fiber optic networks, you will come into contact with many different connector types, the
most common being described below:
ST Connector
ST stands for Straight Tip-a quick release bayonet style connector developed by AT&T. STs
were predominant in the late 80s and early 90s and are still one of the most commonly used
fiber optic connectors in networking applications. They are cylindrical with twist lock coupling,
2.5mm keyed ferrule.
ST connectors are used both short distance applications and long line systems. The ST
connector has a bayonet mount and a long cylindrical ferrule to hold the fiber.
FC Connector
FC stands for Fixed Connection - it is fixed by way of a threaded barrel housing. FC
connectors are typical in test and measurement environments and for single- mode
applications.
FC is the fiber optic connector standard for Nippon Telephone & Telegraph (NTT) installations,
developed with Nippon Electric Co. (NEC).
The FC screws on firmly, but make sure the key is aligned in the slot properly before
tightening.
