WDM Product

Since the physical fiber optic cabling is expensive to implement for each and every service separately, its capacity expansion using a Wave Division Multiplexing (WDM) is a necessity. WDM technology was developed to expand capacity of networks single fiber can provide. A WDM system uses a Multiplexer at the transmitter to combine several wavelengths together, each one carry different signal and a demultiplexer at the receiver to split them apart. Both Mux and Demux are passive, requiring no power supply.

Nowadays there are several kinds of standardized WDM in existence: –General WDM, such as 980/1550 WDM, 1310/1550 WDM. —CWDM include CWDM mux/demux module and CWDM OADM module. The common configuration of CWDM mux/demux module is 2CH, 4CH, 8CH, 16CH, 18CH CWDM mux/demux module. Single fiber or dual fiber connection for CWDM Mux/demux are available. –DWDM include 50GHz, 100GHz, 200GHz DWDM mux/demux module and DWDM OADM module. The common configuration is 2CH, 4CH, 8CH, 16 CH, 32CH, 40CH channels.

They are available in the form of Plastic ABS module cassette, 19’’ rack mountable box or standard LGX box. And no matter what kind of connectors, like FC, ST, SC, LC etc, all is available on DK Photonics, and we also can mix connector on one device.
