WDM couplers

Four-channel dense wavelength-division-multiplexer couplers are available for telecommunications and CATV systems that use the 1550-nm bandpass window of fiber. The dense WDMs work at 1533, 1541, 1549, and 1557 nm. The couplers use the company`s fused biconic taper and filter technologies and are packaged in either a standard flat pack or the 948 Series fiber-management coupler cartridge.
