2×2 1310 & 1550nm Dual Window Singlemode FBT Coupler Splitter With Steel Tube

2×2 1310 & 1550nm Dual Window Singlemode FBT Coupler Splitter With Steel Tube

The 2×2 1310 & 1550nm Dual Window Singlemode FBT Coupler Splitter With Steel Tube is a high-performance optical splitting and combining device engineered for reliable operation across both 1310 nm (O-band) and 1550 nm (C-band) wavelength windows. Utilizing advanced Fused Biconical Taper (FBT) technology, this splitter delivers low insertion loss, precise coupling ratios, excellent wavelength stability, and consistent bidirectional optical performance in dual-wavelength singlemode fiber networks.

Encapsulated in a rugged stainless-steel protective tube, the device provides superior mechanical strength, environmental resistance, and long-term operational stability. Its precision fused-taper process ensures low polarization-dependent loss (PDL) and uniform optical characteristics, making it suitable for demanding network environments and multi-wavelength optical transmission systems.

With its 2×2 configuration, the coupler splitter supports flexible operation as both a splitter and a combiner, allowing efficient optical power distribution or merging within dual-window systems. Available in various split/coupling ratios—such as 50/50, 60/40, 70/30, 80/20, and 90/10—the device is widely used in FTTH/FTTx deployments, PON networks, CATV systems, CWDM/DWDM monitoring, optical sensors, and laboratory testing applications requiring precise and reliable dual-band performance.
