SC Fiber Coupler

This SC fiber coupler, also known as SC fiber flange or adapter, is a passive optical connection component used to butt-join two SC fiber connectors together to extend fiber cable length or realize fiber distribution on patch panels. It is widely used in ODF fiber distribution frames, fiber optic terminal boxes, FTTH distribution boxes, telecom rooms and data center cabling systems.

Adopting high-precision zirconia ceramic sleeve, it ensures accurate alignment of the fiber cores at both ends, achieving ultra-low insertion loss and high return loss, with excellent plugging repeatability and interchangeability. The precision-machined housing ensures tight fit with standard SC connectors, providing stable and reliable optical connection after thousands of plug-in cycles.

It supports both single-mode and multi-mode SC fiber connectors. UPC version with blue housing is for standard data network cabling; APC version with green housing is for CATV, PON and FTTH systems requiring higher return loss. The snap-in mounting design fits standard ODF patch panels and fiber terminal boxes directly, making installation quick and tool-free.

Available in bulk packing and individual packaging. We support custom housing color, logo printing and private-label packaging for large-volume OEM orders, suitable for telecom contractors, FTTH installers and fiber optic accessory distributors.
