2×2 1550nm Single Window Singlemode FBT Coupler Splitter With Steel Tube

2×2 1550nm Single Window Singlemode FBT Coupler Splitter With Steel Tube

The 2×2 1550nm Single Window Singlemode FBT Coupler Splitter With Steel Tube is a high-performance optical power-splitting and combining device designed for reliable operation in 1550 nm C-band singlemode fiber networks. Using advanced Fused Biconical Taper (FBT) technology, this 2×2 coupler splitter provides low insertion loss, high splitting accuracy, excellent wavelength stability, and stable bidirectional optical performance.

Encapsulated in a rugged stainless-steel tube, the device offers superior mechanical protection, environmental resistance, and long-term operational stability. The precision fused-taper manufacturing process ensures low polarization-dependent loss (PDL) and uniform optical characteristics, making it suitable for a variety of robust deployment environments.

The 2×2 configuration allows flexible operation as either a splitter or a combiner, enabling efficient optical power distribution or merging in applications such as FTTH/FTTx systems, PON architectures, CATV networks, CWDM/DWDM monitoring, optical sensors, and test setups.

Available in multiple coupling/split ratios—including 50/50, 60/40, 70/30, 80/20, and 90/10—it supports diverse system designs requiring accurate and consistent power management at 1550 nm.
