25G/50G/100G/200G DWDM Division Multiplexer

The 1 x 2 -  1x32 DWDM division multiplexer or demultiplexer is based on our advanced fiber Bragg grating filter technology and has 1x2 - 1x32 ports for multiplexing or demultiplexing. One of significances  of  this DWDM MUX or DEMUX is flexibility of working wavelength which can be any at ITU grid or customer specified.   This module can be used to separate or combine 2 - 32 channel signal at any note in a DWDM network system. Our high quality DWDM 1x2 - 1x32 division multiplexer shows that it is ideal component for 200G, 100GHz, 50GHz and 25GHz DWDM system applications.

Customer made 1x2 - 1x32 DWDM or CWDM division multiplexer with any pass bandwidth and any channel spacing  is also available .

Any channel number from 1x2  to 1x32 DWDM, CWDM division multiplexer can be made according to customer specs.
