2×2 850nm Single Window Multimode FBT Coupler Splitter With ABS Box

The 2×2 850nm Single Window Multimode FBT Coupler Splitter With ABS Box is a high-performance optical splitting and combining device designed specifically for 850 nm multimode fiber systems, commonly used in short-reach communication, LAN networks, and VCSEL-based transmission. Built using advanced Fused Biconical Taper (FBT) technology, it delivers stable optical power distribution, low excess loss, accurate coupling ratios, and consistent bidirectional operation within the 850 nm operating band.

Encapsulated in a durable ABS protective box, the splitter provides excellent mechanical strength, easy installation, and long-term environmental protection. The precision fused-taper structure ensures uniform power splitting and highly reliable performance across all output ports, making it ideal for applications where stability and repeatability are critical.

With a versatile 2×2 configuration, the device functions effectively as both a splitter and a combiner, offering deployment flexibility for a wide range of multimode networks. Available in multiple split/coupling ratios—such as 50/50, 60/40, 70/30, 80/20, and 90/10—it is widely used in LAN communication, VCSEL-based optical links, multimode sensing, optical monitoring, and fiber-optic testing environments.
