 Dense Wavelength Division Multiplexing (DWDM) Testing
At its simplest, a dense wavelength division multiplexed (DWDM) system can be viewed as a parallel set of optical channels, each using a slightly different light wavelength, but all sharing a single transmission medium.
This new technical solution can increase the capacity of existing networks without the need for expensive recabling and can significantly reduce the cost of network upgrades.
