    Reviews provides WDM couplers or multiplexers for special wavelengths. These optical couplers are manufactured using fused fiber technique. They combine and split signals at 1064nm and 1550nm, or 1550nm and 1625nm, with low insertion loss, polarization insensitive, high reliability and high isolation.

Other available wavelengths include 980/1310nm, 1064/1310nm WDM couplers.

Thin-film filter based 1550/1625nm WDM couplers are also available. Comparing to fused fiber WDM couplers, these WDMs have lower insertion loss, higher isolation and much wider operating optical bandwidth.
