40 channels DWDM MUX DEMUX Dual Fiber LC/UPC 1U Rack w/1310nm & Mon CH21-CH60


40CH 100GHz CH21-CH60 Dual Fiber LC/UPC, with 1310nm and Mon, DWDM Mux & Demux 1U Rack Mount; 3.0dB Typical IL, AAWG technology for lower loss

The 40 channel DWDM Mux is a passive optical multiplexer/demultiplexer designed for metro access applications that represent the state of the art in fiber optics design. This passive DWDM Mux Demux module multiplexes and demultiplexes 40 DWDM wavelengths of 100GHz ITU Grid channel spacing into a ring or point-to-point network. And the main advantage of DWDM Mux Demux is its passive nature – no power supply or cooling necessary, robustness – no special micro-climate requirements and as passive element, it has MTBF 100+ Years. 

40 channel DWDM Mux Demux, designed by LightOptics® is based on AAWG (Athermal Arrayed Waveguide Grating) technology, allowing to organize 40 duplex, protocol independent parallel ITU-T G.694.1 compatible Dense Wavelength Division Multiplex (DWDM) data streams over pair of single mode optical fiber.
The Mux DWDM is used with colored transceivers such as DWDM SFP, XFP, SFP+, SFP28 transceivers, it's transparent to any rate, any service multiplexing and upgrade, such applications as 1G/10G/25G Ethernet, SDH/SONET and 8/4/2/1G Fiber Channel. So it is usually flexible mix of DWDM SFP, DWDM-SFP10G-40 ( DWDM SFP 40km ), DWDM XFP and 25G DWDM

It is packaged with a 1U 19'' rack mount chassis for simple installation and modularity. This rack chassis system offers network equipment manufacturers a more scalable and higher-density solution to add DWDM capability to their existing and new networks with simple pluggable interface and upgrade CWDM networks by 1550nm or 1530nm window.
