Marconi Ericsson NTM1011156/1 Marconi/Ericsson SMA/OMS/MSH86 SDH transmission systems Optical Transmission Module

The Marconi Ericsson NTM1011156/1 is an AC/DC bracket kit for the OMS 846 optical multiplexer shelf, a mechanical fitting kit for mounting or converting the shelf’s power-feed arrangement between AC and DC supply options rather than an active circuit card. The OMS 846 sits within the OMS range’s lower-capacity end, alongside the OMS 840 and other variants also covered in this listing, providing metro/access SDH multiplexing as the successor generation to Marconi’s SMA platform. A correct bracket kit is needed when a shelf is being installed into a site with a different power arrangement than it originally shipped for, or when a spare shelf is being reconfigured to match an existing installation’s supply. OMS equipment, part of the same GPT/Plessey-derived transmission lineage Marconi sold to Ericsson in 2006, remains in service on UK access transmission networks. Confirm the exact power configuration your OMS 846 installation needs before ordering. Tech-Star (UK-based, shipped worldwide) stocks Marconi Ericsson OMS components to support ongoing network maintenance projects.
