Mini steel tube type 1x2 / 2x2 Fused Fiber Optic Coupler is kind of passive optical network (PON) component, which main function is to redistribute the input light power as required. Our FBT fiber optic coupler / splitter employs Fused Biconical Tapered (FBT) technology and fully compliant with Telcordia GR-1209/1221 standards for network applications.

Fusion fiber optic coupler with stainless steel tube is available in both 1x2 and 2x2 port configurations. According to customer’s needs, SC, LC, FC, ST connectors could be pre-terminated at both input and output ends.
