Virtual1 Deploys MetroWAVE in City

Virtual1 has deployed ‘MetroWAVE’ Optical Multiplexers from Metrodata Ltd. for the heart of its recently launched London-wide fibre infrastructure.

Network Equipment Manufacturer Metrodata worked with Virtual1 to design a key element of the Metro-area fibre network, stretching from Docklands in the East right though to Heathrow and Woking in the West.

Each MetroWAVE Mux/Demux unit supports 8 fibre services, each of up to 10Gbps, over different wavelengths within the ‘Coarse Wavelength Division Multiplexing’ (CWDM) spectrum, in addition to accommodating a conventional ‘wideband’ service at the 1310nm wavelength, used by default for fibre connection by equipment vendors.

As Managing Director of Metrodata, Richard Kirby, explains “The key benefits to Virtual1 of the inclusion of our MetroWAVE multiplexers at the heart of their fibre network are the simplicity, low cost and speed of both initial deployment and subsequent expansion. The units occupy an extremely small footprint and offer massive network throughput expansion in cost-effective modular increments.” Each multiplexer takes just one third of a single unit (1U) of rack space and offers expansion via CWDM and/or DWDM (Dense Wavelength Division Multiplexing) up to 230 Gbps of network capacity within a single rack unit and then potentially to over 340 Gbps within 2U.

Kirby points out that whilst optical multiplexing is neither new, nor Virtual1’s approach radical, some key equipment design steps have been taken by both parties to ensure that the cost-effectiveness of Passive optical technology does not compromise performance, particularly in relation to driving distances around the fibre ring. “Our equipment has been optimised for modular expansion with minimal optical power loss, which is essential to ensure effective signal reach around the Metro network”. The result, for Virtual1, is a fibre network core which is resilient and can be quickly and simply expanded, all at low cost and using minimal space and power, both of which are at a premium in the Data Centre environment.

James Hickman, Chief Technical Officer of Virtual1 said: “We chose MetroWAVE equipment because of the simplicity of the solution, low maintenance requirement and excellent scalability. Metrodata were a delight to work with as they are a very responsive supplier and were keen to work closely with us to ensure their product fitted our needs.”
