CWDM Switches
Wavelength Division Multiplexing -WDM-is a method of transmitting data from different sources over the same fiber optic link at the same time whereby each data channel is carried on its own unique wavelengthover a fiber optic cable.Typically WDM is using to increase signalling and bandwidth capacity over singlemode fiber optic cable, The result is a link with an aggregate bandwidth that increases with the number of wavelengths employed. In this way WDM technology can maximize the use of the fiber optic infrastructure that is available; what would normally require two or more fiber links instead requires only one. Dense Wave Division Multiplexing (DWDM) combines up to 64 wavelengths onto a single fiber. DWDM technology uses an ITU standard 100GHz or 200GHz spacing between the wavelengths, arranged in several bands at ~1500-1600nm. With DWDM technology, the wavelengths are close together (compared to CWDM), meaning that transponders are generally more complex and expensive than CWDM. However, with DWDM, the advantage is a much higher density of wavelengths, and also longer distances, especially with MRV's low dispersion solution for the Fiber Driver-LD system. WDM technology is made up of a number of building blocks. When put together into a network, these blocks provide a complete solution for multi-wavelength services, and bandwidth enhancement over a single or dual fiber strand..

& Multiplexing:
For Flash Demo Multiplexing
is the process of combining several data streams operating at
unique wavelengths on several fibers onto a single fiber "trunk".
Demultiplexing is just the opposite, taking a fiber trunk and
separating it into individual fibers, each transporting a different
wavelength signal. An Add/Drop Multiplexer takes a single wavelength from a trunk, pulls the signal out, and allows a new signal at the same wavelength to be inserted into the trunk at (roughly) the same spot. All the other wavelengths pass through the add/drop mux with only a small loss of power (usually a few dB). This concept is especially important when planning WDM networks, and plays an important role in the overall distance a WDM network can span. Sub-Rate
Multiplexing:
For Flash Demo Sub-rate
Multiplexing is the process of placing several data streams onto
a single wavelength, in an effort to further increase the number
of data streams in a WDM system. There are several mechanisms
of sub-rate multiplexing: This example shows how multiple channels of ESCON can be converted with the Fiber Driver-LD ESCON Solution into a single wavelength before wave division multiplexing, allowing up to 64 ESCON channels on a 16 wavelength CWDM system, or hundreds of ESCON channels using DWDM. The LD product also offers 2-Port Gigabit Ethernet Multiplexing modules. Cross-Connects:
For Flash Demo A
cross-connect is a device that allows an administrator to select
which port will have a connection to which other port or ports.
This example shows the configurability of the NC316-XP Media Cross
Connect. Cross-connects have several uses in WDM systems:
