19'' 1U Chassis DWDM MUX DEMUX 4 Channels -40~85 °C

WAREX DWDM Multiplexers multiplex and demultiplex optical DWDM wavelengths using high quality filters. They fully support ITU G.694.1 and are the ideal way to add more capacity to an existing fiber network. By multiplexing up to 16 DWDM wavelengths, the capacity of the fiber will be increased significantly. It configues 16, 8 ,4 ,2 channel multiplexers, which allowing network operators to implement point-to-point, ring and meshed DWDM networks. The DWDM Multiplexers modules are completely passive and therefore do not require electrical power.

The modules are based on 19”1U Chassis, which offer a very easy installation and connection process. Industry practice wavelength nomination allows easy set-up and installation resulting in a true Plug and Play experience.
