DWDM
Unlimited Scalability for Fiber-Optic Networks
Dense Wavelength Division Multiplexing (DWDM) is an optical multiplexing technology used to increase bandwidth over existing fiber networks. DWDM works by combining and transmitting multiple signals simultaneously at different wavelengths on the same fiber. The technology creates multiple virtual fibers, thus multiplying the capacity of the physical medium.

Driving down the Cost per GbE Kilometer
WDM has revolutionized the cost per bit of transport. Thanks to DWDM, fiber networks can carry multiple Terabits of data per second over thousands of kilometers – at cost points unimaginable less than a decade ago. State-of-the-art DWDM systems support up to 160 wavelengths on a single pair of fiber, with each wavelength transporting up to 40Gbit/s capacity. 100Gbit/s per wavelength will enter the market later in 2011.
Web 2.0 without DWDM? Unthinkable!
DWDM provides ultimate scalability and reach for fiber networks. Without the capacity and reach of DWDM systems, most Web 2.0 and cloud-computing solutions today would not be feasible. Establishing transport connections as short as tens of kilometers to enabling nationwide and transoceanic transport networks, DWDM is the workhorse of all the bit-pipes keeping the data highway alive and expanding.
