Single Mode Single Window Fused Coupler : 1x2, 2x2 (1310nm,1550nm)
Fused fiber optic coupler (Fused Coupler) is a device based on Fused Biconical Taper (FBT) technology, is designed for power splitting. It’s a device with one or more input fibers and one or several output fibers.
It’s been used in many fields, such as optical communication system, CATV networks, fiber optic sensor, Optical Amplifier, FTTH/PON, LAN, and test equipment.
VFibre’s fused coupler features low insertion loss, low polarization dependent loss, wide bandwidth, environmentally stable and reliability.
