1×2 1550nm Single Window Singlemode FBT Coupler Splitter With Steel Tube

1×2 1550nm Single Window Singlemode FBT Coupler With Steel Tube

The 1×2 1550nm Single Window Singlemode FBT Coupler Splitter With Steel Tube is a high-performance optical power-splitting device designed for stable and accurate optical signal distribution in singlemode fiber networks. Manufactured using Fused Biconical Taper (FBT) technology, this device provides excellent optical uniformity, low insertion loss, and high splitting accuracy within the 1550 nm single-window operating wavelength, making it suitable for C-band optical communication systems.

Encapsulated in a durable stainless-steel protective tube, the coupler splitter offers superior mechanical protection, environmental stability, and long-term reliability for both indoor and outdoor deployments. With low polarization dependence and high wavelength stability, it ensures consistent performance across various fiber-optic applications.

Available in a wide range of split/coupling ratios—including 50/50, 60/40, 70/30, 80/20, and 90/10—the device is widely used in FTTH/FTTx networks, PON systems, optical monitoring, CATV, DWDM/CWDM networks, and other fiber-optic links requiring precise signal distribution.
