1×2 1310 & 1490nm Dual Window Singlemode FBT Coupler Splitter With Steel Tube

1×2 1310 & 1490nm Dual Window Singlemode FBT Coupler Splitter With Steel Tube

The 1×2 1310 & 1490nm Dual Window Singlemode FBT Coupler Splitter With Steel Tube is a high-performance optical splitting device designed for stable and accurate power distribution across both the 1310 nm and 1490 nm wavelength windows. Utilizing advanced Fused Biconical Taper (FBT) technology, this splitter ensures low insertion loss, high splitting accuracy, and excellent wavelength stability, making it ideal for FTTx, PON, and multi-wavelength communication systems.

Encapsulated in a durable stainless-steel protective tube, the device offers superior mechanical protection and environmental resistance, ensuring long-term optical stability even in harsh deployment conditions. The high-quality fused taper process provides low polarization-dependent loss (PDL) and consistent performance across both dual operating wavelengths.

Available in various coupling/split ratios such as 50/50, 60/40, 70/30, 80/20, and 90/10, this FBT coupler splitter is widely used in FTTH/FTTx networks, PON (EPON/GPON) systems, optical monitoring, CATV links, and fiber-optic testing setups requiring precise and reliable power distribution.
