1550nm Dual Window Coupler

1310/1490/1550nm Without Connector FTTH Fiber Optic Fbt Coupler

FBT Description

Fiber Optic FBT splitter is a type of optical power management device that is fabricated using Fused Biconical Tape Technology. It features small size, high reliability, cheap cost and good channel-to-channel uniformity,and is widely used in PON networks to realize optical signal power splitting.
SUNET provide a reliable solution to split/combine signals.The splitting ratio ranges from 1x2 to 1x32 ports for tree couplers, and from 2x2 to 2x32 for star couplers. Available in single,dual and triple wavelength windows(1310/1490/1550nm).

FBT Feature

1. Low Excess Loss

2. Various Coupling Ratio

3. Compact Size

FBT Application

1. Long-haul Telecommunications

2. CATV Systems &Fiber optic Sensors

3. Local Area Network
