3M SC 126um Singlemode Connector
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 newer network 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 simple push-pull motion and is keyed. They feature a 2.5mm ferrule and molded housing for protection. Typical matched SC connectors are rated for 1000 mating cycles and have an insertion loss of 0.25 dB.
Knowledgebase: 3M has simplified the design of the SC Connector to enhance performance and cable retention and provide readily field mountable connectors. The 3M™ SC Connector has a rectangular push-pull coupling mechanism for easy insertion and high repeatability. The zirconia ceramic ferrule, with a proprietary PC finish assures low attenuation and can now minimize reflected power to -55 dB on factory polished single-mode cable assemblies. The SC Connector is designed for the most advanced fiber optic systems requiring exceptional stability, low reflections (single-mode) and high density. This versatile connector offers easy installation in both long and short transmission lines, subscriber networks or premises environments.
