Marconi Ericsson SU65AA Marconi/Ericsson SMA/OMS/MSH86 SDH transmission systems Optical Transmission Module

The Marconi Ericsson SU65AA is an SFP transceiver for the OMS1200 optical multiplexer, providing an STM-1 electrical (STM-1E) interface over 1.0/2.3mm coaxial cabling rather than fibre, an electrical rather than optical aggregate or tributary port. The OMS1200 is a compact-capacity member of the OMS range covered elsewhere in this listing, and like the other SFP-based OMS variants in this batch it takes pluggable interface modules rather than fixed ports, letting a shelf be configured with electrical or optical interfaces at each position as the site needs. STM-1E coax interfaces are typically used for short local hops or interconnects within a building or equipment room where running fibre is unnecessary. OMS equipment, part of the same GPT/Plessey-derived transmission lineage Marconi sold to Ericsson in 2006, remains in service on UK metro and access networks. Confirm your OMS1200 shelf’s SFP cage type before ordering. Tech-Star (UK-based, shipped worldwide) stocks Marconi Ericsson OMS components to support ongoing network maintenance projects.
