What types of connectors are available?
Many different types of connectors are used throughout the world but the most common are detailed below:- ST (Straight Tip) – most commonly used for Multi Mode fibre systems, the connector provides Physical Contact (PC) properties by spring loading of the ferrule. A bayonet keyed fixing method maintains accurate alignment of the ferrule. They may also be used for some Single Mode Fibre systems where high Insertion Loss (IL) and low Return Loss (RL) can be tolerated. Available only as simplex connectors. FC (Fibre Connector) – most commonly used connector for low loss Single Mode Fibre systems but also used for Multi Mode systems as well. Physical Contact (PC) properties are maintained by spring loading of the ceramic ferrule. Accurate alignment is maintained by the use of key way and threaded connector retention. Most optical test equipment, such as OTDR’s, are fitted with FC connection output facilities to maintain accuracy of measurement. Available only as simplex connectors. SC (Sub
