Ericsson ROJ1192257/2 AXE-10 / RBS transport subsystem Optical Transmission Module

The Ericsson ROJ1192257/2 is an STM-1/OC-3 optical transmission interface board from Ericsson’s AXE-10 and associated RBS transport equipment range, also referenced in equipment reseller documentation under the designation ET-C41. It provides a 155 Mbit/s STM-1 (SDH) / OC-3 (SONET) optical line interface used to carry aggregated voice and data traffic between Ericsson network elements over fibre transmission links, forming part of the transport layer that connects radio base station sites back into the wider core and transmission network.

Boards of this type are typically fitted into AXE-10 exchange subracks or RBS-associated transport subsystems to provide, extend, or replace STM-1/OC-3 optical transmission capacity on legacy Ericsson networks. As with all Ericsson transport and exchange hardware still in service today, these boards are valued by network operators and maintenance contractors for keeping existing infrastructure running without a full platform replacement, and for holding as spares cover against field failures.

This unit is supplied as a genuine, previously-installed Ericsson OEM part, visually inspected prior to listing. Tech-Star (UK-based, shipped worldwide) stocks a wide range of legacy and current Ericsson transmission, radio, and exchange hardware.
