To maximise the potential of having access to dark fibre links, whether owned or leased, in some situations it is advisable to utilise Wavelength Division Multiplexing (WDM). This allows a number of channels to be carried over a single duplex or simplex fibre path, each channel capable of carrying anything from 100Mb/s to the latest 100Gb/s technology.
There are many challenges in deploying this technology due to the tight optical margins and the need to appreciate optical losses in all parts of the system, which requires significant training and experience. The staff at TNP have a proven track record of designing and implementing a number of complex WDM solutions, some carrying many 10Gb/s channels with single hops of over 120km.
