ALCATEL 3AL78848BAAM -Lucent 1660SM MATRIXN Telecom System Card / Module

The Alcatel-Lucent 3AL78848BAAM is a MATRIXN card for the Alcatel-Lucent 1660SM SDH optical transmission platform, a metro and regional transport system supporting speeds up to STM-64. The MATRIXN card performs the shelf’s core cross-connection and synchronisation functions, providing the switching fabric that grooms and routes traffic between the various port and tributary cards fitted in a 1660SM subrack, alongside timing and synchronisation reference distribution across the shelf. As the central switching element of the subrack, a working MATRIXN card is essential to the operation of the whole shelf; most 1660SM deployments run MATRIX cards in a protected configuration so that a spare can take over cross-connect duties if the active unit develops a fault. This unit carries the AM revision suffix, part of the wider 3AL78848B family of MATRIXN cards used across 1660SM deployments; the base board type and cross-connect function are confirmed and consistent across the family’s revision variants. It is commonly sourced as a tested pull when maintaining an existing 1660SM ring or provisioning spares against manufacturer end-of-life on new-build SDH hardware. Tech-Star (UK-based, shipped worldwide) stocks tested Alcatel-Lucent 1660SM cards including matrix, port and power units; contact our engineers to confirm the right revision for your shelf before ordering.
