2×2 1310nm Single Window Singlemode FBT Coupler Splitter With Steel Tube

2×2 1310nm Single Window Singlemode FBT Coupler Splitter With Steel Tube

The 2×2 1310nm Single Window Singlemode FBT Coupler Splitter With Steel Tube is a high-precision optical splitting and combining device designed for stable and reliable operation at the 1310 nm O-band wavelength. Manufactured using advanced Fused Biconical Taper (FBT) technology, this 2×2 coupler splitter ensures low insertion loss, accurate splitting ratios, excellent wavelength stability, and consistent bidirectional optical performance in singlemode fiber networks.

Housed in a durable stainless-steel tube, the device provides superior mechanical protection, environmental resistance, and long-term operational reliability, making it suitable for demanding indoor and outdoor deployment environments. Its precision fused-taper structure offers low polarization-dependent loss (PDL) and uniform power distribution across all output ports.

With its 2×2 configuration, the device supports flexible operation as both a splitter and a combiner, allowing efficient optical power distribution or merging in various fiber-optic systems. Available in multiple coupling/split ratios—such as 50/50, 60/40, 70/30, 80/20, and 90/10—it is ideal for FTTH/FTTx networks, PON systems, CATV distribution, CWDM/DWDM monitoring, optical sensing, and laboratory testing.
