1×2 850nm Single Window Multimode FBT Coupler Splitter With Steel Tube

The 1×2 850nm Single Window Multimode FBT Coupler Splitter With Steel Tube is a high-performance optical power-splitting device designed specifically for 850 nm multimode fiber networks, including short-reach data communication and sensing applications. Built using advanced Fused Biconical Taper (FBT) technology, this splitter ensures stable optical power distribution, low excess loss, accurate coupling ratios, and excellent performance within the 850 nm operating window.

Encapsulated in a rugged stainless-steel protective tube, the splitter offers strong mechanical durability and resistance to environmental variations, providing long-term stability in both laboratory and field conditions. The precision fused-taper structure guarantees uniform splitting across outputs, making it suitable for multimode optical systems that require consistent and reliable optical characteristics.

Available in a range of split/coupling ratios—such as 50/50, 60/40, 70/30, 80/20, and 90/10—the device is widely used in LAN networks, short-distance multimode communication links, VCSEL-based systems, multimode sensors, optical monitoring setups, and various test environments.
