JUNE 9, 2008 -- Galazar Networks Inc. (search for Galazar) has introduced the MXP product family, designed to address metro networking applications by combining the next-gen SONET/SDH functions of an MSPP and the OTN functions of a transponder to provide a muxponder-on-a-chip. The device enables ROADM equipment providers to reduce the costs and increase efficiencies of their equipment in the service provider's network, Galazar says.
Increasing bandwidth demands in the metro network have forced service providers to use their WDM wavelengths more efficiently. Rather than dedicating an entire wavelength to a single service, providers can maximize their investments by multiplexing a number of revenue generating services on a single wavelength. Up to now, achieving this has required an MSPP to multiplex rate- and protocol-diverse customer services and a separate transponder to feed into a WDM network. The MXP family combines these functions to enable development of a single muxponder platform, reducing the capital and operating costs of carrier networks, Galazar explains.
Muxponding functions currently exist on some DWDM/ROADM equipment, but the older, multi-chip designs on which they are based do not support the latest requirements in key service growth areas such as SANs and high-definition video transport, Galazar asserts. Muxponder cards based on Galazar's MXP family can efficiently address all service types including Ethernet, SONET/SDH, SAN, and video, the company continues. This allows equipment manufacturers to add new services to existing platforms or consolidate multiple, service specific cards while reducing space, power, and cost.
The MXP product family comprises devices addressing muxponder applications from 2.5 up to 40 Gbits/sec. The first of these is the MXP2, which provides a single-chip approach for 10-Gbit/sec muxponder applications.
