Coarse Wavelength Divison Multiplexer/Demultiplexer Module (CWDM Mux/Demux) can be a flexible, low-cost solution that capable of combining nine optical signals into a fiber pair. The CWDM Mux/Demux is made to interoperate with the WaveReady type of transponder and optical regenerator solutions as well as CWDM transponders and small form-factor pluggables (SFPs) used in accessible transmission equipment.

Common utilizations of CWDM technology would be the multiplexers and de-multiplexers or optical amplifiers to further improve the capacity with the fiber optic cable. The CWDM Mux/Demux modules including CWDM MUX and CWDM Demux, are made to multiplex multiple CWDM channels into a couple of fibers. Along with highly reliable passive optics certified for environmentally hardened applications, the CWDM Mux/Demux lets operators use available fiber bandwidth in local loop and enterprise architectures.

Based on the wavelength or running channels with the each signal, CWDM MUX/DEMUX includes 4CH, 5CH, 8CH, 9CH, 16CH, 18CH CWDM Mux/Demux. These CWDM MUX/DEMUX can be purchased in 19" Rack Mount or LGX module package.

CWDM provides the most economic and efficient wavelength division multiplexing solutions for metro edge and access networks. Ingellen CWDM products cover 2 channel, 4 channel, 5 channel, 8 channel, 9 channel, 16 channel and 18 channel CWDM Mux/Demux. Ingellen Technology also provides CWDM OADMs (Optical Add/Drop Module) from 1 to 16 channels for CWDM networks, including 1 channel, 2 channel, 4 channel, 8 channel and 16 channel CWDM OADM.

The CWDM OADMs are passive devices that could multiplex/demultiplex or add/drop wavelengths from multiple fibers onto one optical fiber. Through the use of CWDM technology, individual channels may be optically added or dropped from a fiber pair while allowing pass-through traffic to continue unobstructed over the bus or ring. It offers a superior low insertion loss, high channel isolation, wide pass band, cold sensitivity and epoxy free optical path.

1 channel CWDM OADM Key Features:
Add/drop ITU-T G.695- and G.694.2-compatible CWDM channels onto a fiber pair;
Suitable for utilization in outside-plant fiber splice enclosures;
Upgradeable to 8 channels per fiber;
Provides low-loss pass-through for CWDM channels;
Thermally stable passive optics require no electrical energy.

1 channel CWDM OADM Applications:
Provides fiber conservation or reclamation for CWDM wireless backhaul, broadband, along with other services;
Supports linear (bus) and ring add/drop architectures.
