Marconi Ericsson 1HAT60000GCH 1HAT60000KAN Marconi/Ericsson SMA/OMS/MSH86 SDH transmission systems Optical Transmission Module

The Marconi Ericsson 1HAT60000GCH / 1HAT60000KAN is an optical multiplexer card for the SMA 1 node, Marconi’s smallest and lowest-capacity member of the SMA SDH add/drop multiplexer range, built as a compact standalone unit rather than the larger multi-slot subracks used by the SMA 4/16 and SMA-4/16C variants also covered in this listing. The EMC designation marks this card issue’s electromagnetic-compatibility compliance revision. SMA 1 nodes were typically deployed at smaller sites needing only a modest number of tributary circuits dropped from an SDH ring, where the larger SMA subrack platforms would be over-specified. SMA equipment across the whole range, inherited via GPT and Plessey before passing from Marconi to Ericsson in 2006, remains in service on UK transmission networks that have not migrated to newer SDH or packet-based equipment. Confirm the exact SMA 1 hardware issue your site runs before ordering. Tech-Star (UK-based, shipped worldwide) stocks Marconi Ericsson SMA components to support ongoing network maintenance projects.
