SC CONECTOR Push/pull connector that can also be used with duplex fiber constuction.
SC stands for Subscriber Connector- a general purpose push/pull style connector developed by NTT. SC has an advantage in keyed duplexibility to support send/receive channels. SC Connectors are frequently used for work applications. The SC is a snap-in connector that is widely used in singlemode systems for its performance. The SC connector is also available in a duplex configuration.They offer low cost, simplicity, and durability. SC connectors provide for accurate alignment via their ceramic ferrules. The square, snap-in connector latches with a si
