Cambrian, a provider of dense-wavelength division multiplexing (DWDM) for metropolitan area networks (MAN), will be integrated into Nortel's Optical Business Applications division. Due to be completed within 30 days, the deal will give Nortel...
Telewest will provide a 2,500km optical fibre network based on dense wave division multiplexing (DWDM) and synchronous digital hierarchy (SDH) technologies at up to 10 Gbps. The contract will link each main area switch centre on the One2One network.
Linx will be investing £2m in new gigabit Ethernet technology to boost capacity, but it won't be using Dense Wavelength Division Multiplexing (DWDM) technology, a decision criticised by former Linx boss Keith Mitchell, head of XchangePoint and...
The Ethernet uplink from the DSLAM can be run on a spare fibre or, using a separate wave division multiplexing box, on one already in use by the ATM network. However, few people have the necessary fibre-optics to their home or office, and service...
For instance, FC over optical technologies such as wave division multiplexing (WDM) can mean distances of nearly 200km. Fibre Channel (FC), the dominant communications technology for SANs, is increasingly under the strain of distance.
While it is true to say the vast majority of call centres still use traditional switching (aka Time Division Multiplexing or TDM) and plan to do so for the foreseeable future, IP is progressing towards a point of dominance.
