Marconi 1HAT60785AAV SMA/System-X/MSH86 SDH transmission Optical Transmission Module

The Marconi 1HAT60785AAV is a 40 Mbit/s optical tributary card for Marconi System-X transmission equipment. It presents an optical tributary port at 40 Mbit/s and slides into the transmission subrack alongside the other tributary and line cards on the standard 1HAT keying.

System-X is the digital exchange platform Marconi supplied to the UK network, and equipment of that generation is still maintained rather than replaced at a number of sites, which is why individual cards of this type continue to be called for. The 1HAT60785 base number covers more than one build and the AAV ending identifies this one, so match the suffix rather than substituting another from the same base. Marconi’s transmission business transferred to Ericsson in 2006. Refurbished, with the card checked against your shelf type before it ships.
