2×2 1310nm Single Window Multimode FBT Coupler Splitter With Steel Tube

2×2 1310nm Single Window Multimode FBT Coupler Splitter With Steel Tube

The 2×2 1310nm Single Window Multimode FBT Coupler Splitter With Steel Tube is a high-performance optical device designed for reliable splitting and combining of multimode signals at the 1310 nm operating wavelength. Manufactured using advanced Fused Biconical Taper (FBT) technology, it provides stable optical power distribution, low excess loss, accurate coupling ratios, and highly uniform performance for multimode fiber networks.

Protected inside a rugged stainless-steel tube, the splitter offers excellent mechanical durability and resistance to temperature, humidity, and environmental variations—making it suitable for both field installations and laboratory setups. The precision fused-taper structure ensures consistent bidirectional performance, with minimal power fluctuation across ports.

With its 2×2 configuration, the device can function effectively as both a splitter and a combiner, delivering high deployment flexibility. It is available in a wide range of split/coupling ratios—such as 50/50, 60/40, 70/30, 80/20, and 90/10—making it ideal for various multimode applications including LAN networks, optical monitoring systems, multimode sensors, short-reach data communication, VCSEL-based transmission, and fiber-optic testing environments.
