Transmode, a provider of optical networking solutions, has been selected by the Madrid Metro (Metro de Madrid) for a network improvement project to increase network reliability and to ensure that communications services continue in a disaster recovery situation. Metro de Madrid put out a public tender seeking a solution to interconnect its main communications hubs. These are located at various points on the metro:- Alto del Arenal, Puerta del Sur, Depósito de Canillejas and Campo de las Nacion. The aim of the project was to install a fibre-optic network with built in redundancy between these sites, ensuring that communications services are maintained while minimising the impact of any natural catastrophes or terrorist attacks. In the first phase of the project, Transmode improved the communications network by providing Alto del Arenal and Puerta del Sur stations with a redundant and high-capacity link. Communications are now running between both locations, providing all applications, signalling information and end-user services.
The installation, based on Transmode's TM-Series/TS-Series WDM systems, won the tender because it provided the highest network reliability and the best price/performance ratio. The Transmode solution was integrated into Metro de Madrid's management platform by Indra (a certified partner of Transmode),
Spain's first IT multinational and one of Europe and
Latin America's most important. The solution works with two racks configured to provide redundancy. Duplicates of all functional elements (lasers, transponders, filters, etc.), are located in these racks such that if one part should fail, the other will start to operate immediately. The communications system provides a range of protocols including SDH STM-1, Gigabit Ethernet and 10G, PDH, E1, Fibre Channel 4G and ATM STM-1. These are multiplexed into separate 10G channels generating a secure signal, which is combined with the carrier signal between the nodes.
