Summary of CWDM

WDM (Wavelength Division Multiplexing) is a technique, utilizing a special property of fiber-optics. This property permits the mix of multiple signals onto an individual strand of fiber. Each signal is a member of a different wavelength, of light. Since one wavelength has no effect on another wavelength, the signals don't interfere. And CWDM (Coarse wavelength division multiplexing) is a technology which multiplexes multiple optical signals for a passing fancy fiber optic strand by utilizing different wavelengths, or colors, of laser light to hold the various signals. Through the use of bidirectional communications on the single strand of fiber, network managers can realize a multiplication effect in the capacity of the available fiber infrastructure.

CWDM modules perform two functions. First, they filter the sunshine, ensuring only the desired wavelengths are employed. Second, they multiplex or demultiplex multiple wavelengths, which are applied to just one fiber link. The real difference lies in the wavelengths, which are used. In CWDM space, the 1310-band as well as the 1550-band are divided into smaller bands, each only 20-nm wide. Inside the multiplex operation, the multiple wavelength bands are combined onto a single fiber. Inside a demultiplex operation, the multiple wavelength bands are separated from just one fiber. Generally, a CWDM network takes two forms. A point-to-point system connects two locations, muxing and demuxing multiple signals on one fiber. A loop or multi-point system connects multiple locations, typically using Add/Drop modules.

CWDM MUX and CWDM Demux are designed to multiplex multiple CWDM channels into one or two fibers. In the hybrid configuration (mux/demux), multiple transmit and receive signals could be combined onto just one fiber. Each signal is assigned an alternative wavelength. At each and every end, transmit signals are muxed, while receive signals are demuxed. As an example, inside a simple full-duplex link, the transmit is assigned the 1530-nm wavelength, as the receive signal is assigned the 1550-nm wavelength. Additionally, individual signals can be delivered at points along a hyperlink. A receive signal is demuxed in the link, along with a new transmit signal is muxed onto the link. This application is known as an Add/Drop module.

There are a few benefits of utilizing CWDM here.

(1)Increased Bandwidth/Capacity on Existing Fiber

(2)Capability to Mix Multiple Protocols and Network Speeds Within the Same Fiber Infrastructure

(3)Completely Passive Solution ¡§C No Active Equipment or Complicated Configuration

(4)Modular Design Enables Plug and Play and Expansion Provisioning

(5)Attractive Cost

Using FiberStore equipment, you may use two implementations. In a single approach, FiberStore CWDM GBICs (Gigabit Interface Converters) are put into existing Ethernet switch equipment. The GBIC outputs feed FiberStore, CWDM modules. The other approach adds the FiberStore 3001 CWDM Optical Multiplexer System for the existing outputs of existing Ethernet switch equipment.
