2×2 1310 & 1490nm Dual Window Singlemode FBT Coupler Splitter With ABS Box

2×2 1310 & 1490nm Dual Window Singlemode FBT Coupler Splitter With ABS Box

The 2×2 1310 & 1490nm Dual Window Singlemode FBT Coupler Splitter With ABS Box is a high-performance optical splitting and combining device designed for stable operation at the 1310 nm (O-band) and 1490 nm (E-band) wavelengths. Built using advanced Fused Biconical Taper (FBT) technology, this coupler splitter delivers low insertion loss, precise coupling ratios, excellent wavelength stability, and consistent bidirectional performance in dual-window singlemode fiber networks.

Encased in a durable ABS protective box, the device offers strong mechanical protection, easy installation, and long-term reliability for structured indoor optical distribution environments. Its precision fused-taper fabrication ensures low polarization-dependent loss (PDL) and uniform optical characteristics across all ports, ensuring stable performance under various deployment conditions.

With its versatile 2×2 configuration, the splitter functions effectively as both a splitter and a combiner, enabling flexible integration into a wide range of fiber-optic network applications. Available in multiple split/coupling ratios—such as 50/50, 60/40, 70/30, 80/20, and 90/10—it is widely used in FTTH/FTTx deployments, EPON/GPON PON systems, CATV distribution, CWDM/DWDM monitoring, optical sensing, and fiber testing environments.
