100GHZ 8 Channel DWDM Demux Module Optical Transmission System
CWDM and DWDM module
CWDM and DWDM technologies provide an effective way to share one pair of fiber strands and put together various communications interfaces like: 10G, SONET OC-192, STM-64, Fiber Channel 1G/2G/4G, Gigabit Ethernet, OC3/OC12 or OC48 and E1/T1, just by using different wavelengths of light for each channel.
Our product range includes very affordable solutions for CWDM and DWDM technologies, with minimum or no management, but also carrier class professional solutions with complete management and monitoring functions, redundancy on fiber and power supplies and Telco grade specifications that can go up to 80 channels of DWDM 10G capacity on a single fiber circuit.
Our WDM Optical Mux products are flexible with a low-cost solution that enables the expansion of existing fiber capacity, and available with the Plastic ABS module cassette, 19″ Rack Mountable box and standard LGX packaging. No matter what kind of connectors, like FC, ST, SC, LC, etc., are all available, and we can also mix different connectors on one device.
