2×2 1260~1620nm All Band Singlemode FBT Coupler Splitter With ABS Box

2×2 1260~1620nm All Band Singlemode FBT Coupler Splitter With ABS Box

The 2×2 1260~1620nm All Band Singlemode FBT Coupler Splitter With ABS Box is a high-performance optical splitting and combining device engineered to operate reliably across the entire 1260–1620 nm telecommunications spectrum, covering O, E, S, C, L, and U bands. Designed with advanced Fused Biconical Taper (FBT) technology, this broadband splitter offers low insertion loss, excellent uniformity, precise coupling ratios, and exceptional wavelength stability across all supported wavelengths.

Protected by a durable ABS enclosure, the device ensures strong mechanical protection, easy installation, and long-term environmental reliability. Its precision fused-taper construction provides low polarization-dependent loss (PDL) and stable optical characteristics across all ports, making it ideal for broadband and multi-wavelength fiber-optic applications.

With its 2×2 configuration, the splitter supports flexible functionality as both a splitter and a combiner, enabling efficient bidirectional optical power management. Available in multiple split/coupling ratios—including 50/50, 60/40, 70/30, 80/20, and 90/10—it meets the requirements of various system architectures. It is widely used in FTTH/FTTx deployments, EPON/GPON PON networks, CATV distribution, CWDM/DWDM monitoring, broadband sensing, optical testing, and multi-wavelength communication systems.
