PM Coupler

1X2(2X2) Single Mode Triplex Window Coupler

 

Built by asymmetric coupling technique, Triplex Window Coupler operating bandwidth is expanding to 1310nm, 1490nm and 1550nm three communication windows. The TWC coupler has the same coupling ratio on 1310, 1490 and 1550nm communication windows, with low excess loss and low PDL. TWC is widely used for communication systems, CATV,FTTH,where multiple optical signals pass through single fiber.

 
The products are Telcordia GR-1221/1209-CORE qualified, and RoHS compliant.
