2x2 Polarization Maintaining Coupler PM1550 Fiber FBT Coupler Splitter 1550nm 1m length Slow Axis working
As one of the key components for GPON FTTx networks, optical splitters can be placed in the Central Office or in one of the distribution points (outdoor or indoor) because the FBT splitters are highly stable for multiport optical signal splitting with low insertion loss. FBT couplers are designed for power splitting and tapping in telecommunication equipment, CATV network, and test equipment
