ABSTRACT
The article informs that a quick search of the telecom trade press suggests that dense wave division multiplexing (DWDM) is old hat. However, while DWDM in the carrier backbone may be passe, DWDM in a private network is hot. Here's a peek at what large enterprise customers are doing with it and what one should consider if DWDM is a possibility for one's enterprise. DWDM allows data transmissions to be multiplexed across a single optical fiber in native LAN protocols over different wavelengths or lambdas. For years, carriers have used DWDM in their backbone to increase bandwidth on existing facilities. One may ask why enterprise user interest in DWDM has exploded over the past few years--particularly since 9/11. The reasons are many, but here are the two most often cited: First, DWDM provides tremendous bandwidth capacities--an essential ingredient for data-intensive applications. Unlike big OC-x pipes for which the customer pays a fixed fee regardless of how much capacity is used, carriers typically don't require the customer to pay for unlit wavelengths on a DWDM ring until the enterprise needs them.

    A global standard for optical fibre coarse wave division multiplexing (CWDM) has been agreed by the ITU standards body. CWDM allows the capacity of optical fibres to be increased. It is seen as a cheaper and simpler option to dense wavelength division multiplexing (DWDM) because it uses wider...
