Dual Window Triple Window 50/50 Ratio 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
