FBT Coupler 50:50 Ratio – 1×2 Steel Tube, Triple Window – Pack of 100 Optical Couplers
This FBT Coupler (Fused Biconical Taper) offers an efficient 1×2 optical signal splitting solution with a 50:50 ratio. Designed with a durable steel tube structure and 0.9mm fiber, it supports triple wavelength operation at 1310nm, 1490nm, and 1550nm – making it ideal for FTTH, PON, or telecom networks. With low insertion loss (≤3.5 dB) and minimal excess loss (≤0.15 dB), this optical splitter ensures consistent performance.
The couplers are connector-free, allowing easy splicing into custom configurations. Each pack contains 100 pieces, perfect for bulk fiber optic installations.
