2×2 850nm Single Window Multimode FBT Coupler Splitter With Steel Tube

2×2 850nm Single Window Multimode FBT Coupler Splitter With Steel Tube

The 2×2 850nm Single Window Multimode FBT Coupler Splitter With Steel Tube is a high-performance optical splitting and combining device designed for multimode fiber networks operating at the 850 nm wavelength. Built using advanced Fused Biconical Taper (FBT) technology, this device ensures stable optical power distribution, low excess loss, accurate coupling ratios, and reliable bidirectional operation within short-reach multimode transmission systems.

Encapsulated in a rugged stainless-steel protective tube, the splitter offers superior mechanical strength, excellent environmental resistance, and long-term stability, making it ideal for both field and laboratory applications. Its precision fused-taper structure guarantees uniform optical performance across output ports, even under varying operating conditions.

With its 2×2 configuration, the device functions efficiently as both a splitter and a combiner, offering high flexibility for multimode optical 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 systems, short-distance optical communication, VCSEL-based transceiver setups, multimode sensing, optical monitoring, and test applications requiring stable 850 nm performance.
