1×2 1310 & 1490 & 1550nm Three Window Singlemode FBT Coupler Splitter With ABS Box

The 1×2 1310 & 1490 & 1550nm Three Window Singlemode FBT Coupler Splitter With ABS Box is a high-performance optical power-splitting device designed for stable and accurate operation across the three main telecommunication windows: 1310 nm (O-band), 1490 nm (E-band), and 1550 nm (C-band). Utilizing advanced Fused Biconical Taper (FBT) technology, this splitter ensures low insertion loss, precise splitting ratios, excellent wavelength stability, and consistent optical performance across all three wavelength bands.

Encased in a compact, durable ABS protective box, the device offers enhanced mechanical protection and user-friendly installation, making it suitable for fiber distribution frames, patch panels, and various structured cabling environments. The precision fused-taper design guarantees low polarization-dependent loss (PDL) and uniform optical characteristics, ensuring long-term stability in multi-wavelength networks.

Available in a variety of split/coupling ratios—including 50/50, 60/40, 70/30, 80/20, and 90/10—the three-window splitter supports flexible deployment in a wide range of optical systems. It is widely used in FTTH/FTTx rollouts, EPON/GPON PON networks, CATV systems, CWDM/DWDM monitoring, optical sensing, and test applications requiring broad-band and multi-wavelength compatibility.
