Capacity Services

Broadband connectivity through optical capacity in wavelength

These are unstructured (zero layer) optical capacity services based on Dense Wave Division Multiplexing (DWDM), that have been implemented on Telefonica Wholesale's network. DWDM is a technology for optical communications that multiplexes different wavelengths (lambdas) on a single optical fibre. Each wavelength travels modulated by the information that it is carrying (voice, video, data, etc.). Unlike the SDH or SONET service, the wavelength service does not require a structure management layer in the circuit. Bandwidth is used more efficiently and there is greater transparency of the optical link end to end. This transparency also allows customers to freely configure their own transmission and protection protocols. For precisely this reason, the wavelength service is not offered as a self-healing service. However, the client may configure it as such by using independent wavelengths on Telefonica Wholesale's network switched on the customer's equipment.

All lambda wavelengths are monitored centrally from the Telefonica Wholesale's operating centres, with continuous 24x7 attention
