1310nm Single Mode 2x2 Filter Coupler
The 1310nm Single Mode 2x2 Filter Coupler uses thin-film filter technology to split or combine optical power at a specified coupling ratio within the 1310nm operating band. Its four-port configuration supports bidirectional optical transmission and power monitoring in mobile fiber networks, fiber communication systems, optical sensing, and test equipment. Standard coupling ratios range from 50/50 to 5/95, with custom ratios available. Featuring low insertion loss, low polarization-dependent loss, high stability, and reliable performance, the coupler is manufactured with SMF-28e fiber and housed in a compact stainless-steel package. Coupling ratio, pigtail length, fiber diameter, and connector type can be customized for specific system requirements.
