CWDM OADM (Coarse Wavelength Division Multiplexing Optical Add/Drop Module) is passive device to multiplex/demultiplex or add/drop wavelengths from multiple fibers onto one optical fiber. By using CWDM technology, individual channels may be optically added or dropped from a fiber pair while allowing pass-through website visitors to continue unobstructed over the bus or ring.
Main Features:
Add/drop ITU-T G.695- and G.694.2-compatible CWDM channels onto a fiber pair;
Created for utilization in outside-plant fiber splice enclosures;
Upgradeable to eight channels per fiber;
Provides low-loss pass-through for CWDM channels;
Thermally stable passive optics require no electrical energy.
The CWDM OADM splice packs are in children of flexible, low-cost solutions that expand the proportions of existing fiber. CWDM OADM bidirectional splice packs provide both east and west add/drop functionality and so are readily deployed in existing outside plant splice enclosures. They feature ample room for fiber management and splice holders. The OADM connectors are interfaced to the color-matching CWDM GBICs around the equipment side. Each of the modules are identical size.
Structure
OADM consists of three stages: an optical demultiplexer, an optical multiplexer, and with shod and non-shod a technique for reconfiguring the paths relating to the optical demultiplexer, the optical multiplexer along with a list of ports for adding and dropping signals. The optical demultiplexer separates wavelengths in a input fiber onto ports. The optical multiplexer multiplexes the wavelength channels which are to continue on from demultipexer ports with those in the add ports, onto a single output fiber.
There are four kinds of CWDM OADMs:
Dual Single-Channel OADMs (CWDM-MUX-AD-xxxx?aAllows you to definitely add/drop two channels of the same wavelength in to the two directions of your optical ring. Another wavelengths are undergone the OADM. Dual fiber can be used for both the network along with the CWDM GBIC connections. Eight versions on this OADM are available, one for each and every wavelength associated with. The twin single-channel OADMs are color coded and match the color coding with the CWDM GBICs.
4 channel CWDM OADM (CWDM-MUX-4=)?aAllows you to add/drop four channels (with different wavelengths) into one direction of the optical ring. Another wavelengths are undergone the OADM. Dual fiber can be used for the network along with the GBIC connections. The four wavelengths will 1470 nm, 1510 nm, 1550 nm, and 1590 nm.
8-Channel Multiplexer/Demultiplexer (CWDM-MUX-8=)?aAllows that you multiplex/demultiplex eight separate channels into one set of two fiber. Dual fiber can be used for both the network and also the GBIC connections. The eight available wavelengths are 1470 nm, 1490 nm, 1510 nm, 15300 nm, 1550 nm, 1570 nm, 1590 nm, and 1610 nm.
Single-Fiber 4-Channel Multiplexer/Demultiplexer (CWDM-MUX-4-SFx=)?aAllows you to multiplex/demultiplex four separate channels into one strand of fiber. Dual fiber is utilized to the connections for the GBICs and single fiber is utilized for that network connections. Both models (CWDM-MUX-4-SF1= and CWDM-MUX-4-SF2=) must be used together to create a four-channel single-fiber point-to-point link.
CWDM OADM is only one of the CWDM passive optical system, the other are CWDM MUX/DEMUX and CWDM GBIC. They provide optical networking support for high-speed data communication for metropolitan area networks (MANs) more than a grid of eight CWDM optical wavelengths in ring or point-to-point configurations.
