2×2 1550nm Single Window Singlemode FBT Coupler Splitter With ABS Box

2×2 1550nm Single Window Singlemode FBT Coupler Splitter With ABS Box

The 2×2 1550nm Single Window Singlemode FBT Coupler Splitter With ABS Box is a high-performance optical splitting and combining device designed for stable operation at the 1550 nm C-band wavelength. Utilizing advanced Fused Biconical Taper (FBT) technology, this 2×2 coupler splitter provides low insertion loss, precise coupling ratios, excellent wavelength stability, and consistent bidirectional performance in singlemode fiber networks.

Encased in a durable ABS protective box, the device ensures strong mechanical protection, easy installation, and long-term reliability for structured indoor network environments. Its precision fused-taper construction guarantees low polarization-dependent loss (PDL) and uniform optical performance across all ports, even under varying installation conditions.

With its 2×2 configuration, the splitter functions effectively as both a splitter and a combiner, offering flexible integration for a wide range of optical applications. Available in multiple split/coupling ratios—including 50/50, 60/40, 70/30, 80/20, and 90/10—it is widely used in FTTH/FTTx networks, PON systems, CATV distribution, CWDM/DWDM monitoring, optical sensors, and laboratory test setups.
