Single Mode Couplers & Combiners, Three Operating Windows; 1310, 1490, 1550 nm; Coupling Ratio 1/99 to 50/50; Directivity ≥55 dB; Fiber Type SMF-28e, others
Built by asymmetric coupling technique, LightComm Technology’s TWC series’ operating bandwidth is expanding to 1310 nm, 1490 nm and 1550 nm three communication windows. The TWC coupler has the same coupling ratio on 1310 nm, 1490 nm and 1550 nm 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.
