Ericsson ROJ1192257/1 STM-1/OC-3 optical transmission interface board for Ericsson carrier transport and switching platforms. Tech-Star (UK-based, shipped worldwide).

The Ericsson ROJ1192257/1 is an STM-1/OC-3 optical transmission interface board, designed for Ericsson’s carrier-grade transport and switching platforms. Operating at the industry-standard STM-1 (155.52 Mbit/s) SDH rate, equivalent to OC-3 in SONET terminology, this module provides synchronous optical transport for voice, data and signalling traffic across metro and core telecom networks. It plugs into the applicable Ericsson transmission or exchange subrack as a field-replaceable line interface, converting internal digital signals into standards-based optical line format for onward transmission over fibre. Boards of this type are used to extend or restore STM-1/OC-3 capacity in legacy Ericsson transmission installations still in active service worldwide. Tech-Star (UK-based, shipped worldwide) supplies this board tested and ready to deploy. Get in touch to confirm compatibility with your exact system revision before ordering.
