Filter Based WDM Couplers

Filter based optical WDM (wavelength division multiplexing) couplers provide high performance multiplexing or demultiplexing for various of applications.

Our filter-based WDM product family covers following wavelength windows commonly used in optical fiber systems: 1310/1550nm (for WDM or DWDM optical communications), 1480/1550nm (for high-power DWDM optical amplifier/EDFA), 1510/1550nm (for DWDM multi-channel optical networks) and 980/1550nm or 1064/1550nm (for high performance DWDM optical amplifier/EDFA).

Compared with fused fiber WDM couplers, filter-based WDM components have much wider operating bandwidth, lower insertion loss, higher power handling, high isolation, etc.

WDM couplers that combines some special wavelengths, such as 1420/15xxnm, 840/940nm, 980/1030nm, 980/1310nm, 1064/1310nm, etc are also available.

If you are interested in WDM couplers at those wavelengths, or if you need other wavelengths not listed here, please contact us directly and we can provide customized couplers to meet your demand.
