Marconi Ericsson 03HAT00030ABQ Marconi/Ericsson SMA/OMS/MSH86 SDH transmission systems Optical Transmission Module

The Marconi Ericsson 03HAT00030ABQ is an STM-1/4 interface card for the OMS1600 optical multiplexer, providing an SDH aggregate or tributary port switchable between STM-1 (155Mbit/s) and STM-4 (622Mbit/s) line rates depending on how the shelf is provisioned. The OMS1600 is a metro-capacity member of the OMS range covered elsewhere in this listing, and cards of this kind are what actually carry SDH traffic in and out of a shelf, as distinct from the mechanical brackets and management software also covered in this batch. A dual-rate card gives some flexibility in how a given slot is used as network capacity requirements change, without needing a hardware swap between STM-1-only and STM-4-only variants. OMS equipment, part of the same GPT/Plessey-derived transmission lineage Marconi sold to Ericsson in 2006, remains in service on UK metro transmission networks. Confirm the exact rate your OMS1600 slot is provisioned for before ordering. Tech-Star (UK-based, shipped worldwide) stocks Marconi Ericsson OMS components to support ongoing network maintenance projects.
