The 1×2 FBT Coupler SC/APC is designed for optical signal splitting and distribution in FTTH, CATV, PON, and fiber communication systems. Manufactured using FBT (Fused Biconical Taper) technology, the coupler provides stable optical performance, low insertion loss, and reliable signal transmission for single mode fiber networks.
This 1×2 FBT splitter features a 50/50 coupling ratio and adopts SC/APC connectors to reduce back reflection and improve return loss performance in sensitive optical transmission environments. The compact steel tube structure allows flexible installation inside splice closures, optical distribution boxes, fiber termination boxes, and telecom cabinets.
The splitter supports 1310nm, 1490nm, and 1550nm operating wavelengths and is built using G.652D / G.657A fiber for reliable long-distance optical communication. It also complies with strict optical and environmental standards to ensure stable long-term performance in demanding network conditions.
YingFeng supports OEM and ODM customization including connector types, split ratios, tube colors, fiber lengths, labeling, and packaging according to different FTTH and telecom project requirements.
