30 September 2003 Optic fiber access network through SDH systems
Author Affiliations +
The communication networks, highly specialized, were developed according to the type of transmitted information (vocal signal, data bases, TV signals). Presently, the networks’ evolution is targeted towards high velocities and services integration, networks characterized by SONET/SDH standards. SDH (Synchronous Digital Hierarchy) is the first standard, which provides an integrated system of network management and maintenance, ensures a uniform and global hierarchy of multiplexing and has advantages concerning the configuration of external network types. In this paper is described an access network for voice and dates communications, on optic fiber, built up with LOGES 2M Alcatel access routes (2 Mbps access) and with SDH transmission systems type Alcatel 1641SM (155Mbps).
