Polarization Maintaining Fused Coupler 1x3 (1310nm, 1480nm, 1550nm)
Polarization Maintaining Fused Coupler
1x3 (1310nm, 1480nm, 1550nm)
Fused fiber optic coupler (Fused Coupler) is a device based on Fused Biconical Taper (FBT) technology, is designed for power splitting tapping telecommunication system. It’s been used in many fields, such as optical communication system, CATV networks, fiber optic sensor, channel monitoring, Optical Amplifier, FTTH/PON, LAN, and test equipment. VFibre’s Polarization Maintaining fused coupler features high Extinction Ratio, low insertion loss, low polarization dependent loss, wide bandwidth, environmentally stable and reliability.
