Singlemode Standard Coupler-Singlemode Broadband Coupler
Single Mode Triplex Window Coupler is built with asymmetric coupling technology, and the working bandwidth is extended to three communication windows of 1310nm, 1490nm and 1550nm. This product is widely used in communication systems, CATV, FTTH where multiple optical signals pass through a single optical fiber. Gracyfiber couplers have the same coupling ratio over the 1310, 1490 and 1550nm communication windows, with low excess loss and low PDL. Support customization, the product complies with Telcordia GR-1221/1209-CORE standard, and complies with RoHS standard.
