Ericsson ROJ1192102-22 RBS / BSC (STM-1 transmission) Optical Transmission Module

The Ericsson ROJ1192102-22 is an ET-M4 STM-1/OC-3 optical transmission card, confirmed by two independent telecom equipment resellers as a card pulled from Ericsson mobile phone base station equipment. It belongs to the ET-M4 family of transmission interface boards used to carry synchronous STM-1 (155Mbps) / OC-3 optical or electrical transmission traffic between base stations, BSC/RNC transport nodes and the wider mobile backhaul network in Ericsson’s 2G/3G RBS architecture. The board provides the physical-layer optical interface function within the base station or BSC subrack, working alongside processor and baseband boards to carry the transmission path back into the core network. As this is a legacy 3G-era transmission card, genuine stock is recovered from decommissioned or upgraded base stations and tested before resale, since new manufacture of this board type has long since ceased. Hardware and firmware revision compatibility with the host system should always be verified before installation. Tech-Star (UK-based, shipped worldwide) stocks ET-M4 family optical transmission cards including the ROJ1192102-22 for operators maintaining legacy Ericsson RBS/BSC transport infrastructure.
