Several common Kinds Of CWDM Moudules

Coarse Wavelength Divison Multiplexer/Demultiplexer Module (CWDM Mux/Demux) is really a flexible, low-cost solution that effective at combining nine optical signals in to a fiber pair. The CWDM Mux/Demux is designed to interoperate with the WaveReady distinct transponder and optical regenerator solutions as well as CWDM transponders and small form-factor pluggables (SFPs) utilized in acquireable transmission equipment.

Common utilizations of CWDM technology include the multiplexers and de-multiplexers or optical amplifiers to improve the ability in the fiber optic cable. The CWDM Mux/Demux modules including CWDM MUX and CWDM Demux, are designed to multiplex multiple CWDM channels into 1 or 2 fibers. As well as 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.

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

CWDM supplies the most economic and efficient wavelength division multiplexing solutions for metro edge and access networks.DK Photonics CWDM products cover 2 channel, 4 channel, 5 channel, 8 channel, 9 channel, 16 channel and 18 channel CWDM Mux/Demux.DK Photonics Technology offers 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 can multiplex/demultiplex or add/drop wavelengths from multiple fibers onto one optical fiber. Through the use of CWDM technology, individual channels might be optically added or dropped from a fiber pair while allowing pass-through visitors to continue unobstructed through the bus or ring. It offers low insertion loss, high channel isolation, wide pass band, low temperature sensitivity and epoxy free optical path.

CWDM OADM Key Features:

w   Add/drop ITU-T G.695- and G.694.2-compatible CWDM channels onto a fiber pair;

w   Designed for use in outside-plant fiber splice enclosures;

w   Upgradeable to 8 channels per fiber;

w   Provides low-loss pass-through for CWDM channels;

w   Thermally stable passive optics require no electrical energy.

CWDM OADM Applications:

w   Provides fiber conservation or reclamation for CWDM wireless backhaul, broadband, and other services;

w   Supports linear (bus) and ring add/drop architectures
