1×2 1550nm Single Window Singlemode FBT Coupler Splitter With ABS Box

The 1×2 1550nm Single Window Singlemode FBT Coupler Splitter With ABS Box is a high-precision optical power-splitting device designed for stable signal distribution in singlemode fiber networks operating at the 1550 nm wavelength. Using advanced Fused Biconical Taper (FBT) technology, this coupler splitter offers low insertion loss, high splitting accuracy, excellent wavelength stability, and reliable performance within the C-band transmission window.

Protected by a compact ABS plastic enclosure, the device provides excellent mechanical durability, easy handling, and convenient installation for both indoor network distribution and patch panel integration. The high-quality fused-taper design ensures low polarization-dependent loss (PDL) and uniform power splitting, making it suitable for a wide range of applications.

Available in various splitting/coupling ratios such as 50/50, 60/40, 70/30, 80/20, and 90/10, this FBT coupler splitter is widely used in FTTH/FTTx deployments, PON systems, CATV networks, CWDM/DWDM monitoring, optical testing, and fiber-optic sensing setups.
