Marconi/Nokia T30810.01 Nokia Synfonet / Marconi SDH transmission Optical Transmission Module

The Marconi/Nokia T30810.01 is the Synfonet DC power supply assembly, listed by Nokia as the DC-PSA in its 19 inch and ETSI rack form. It takes the site DC feed and conditions it for the subrack behind it, so it is shelf infrastructure rather than a traffic carrying unit, and it is normally fitted in pairs so a node keeps running through a supply failure. Power assemblies are matched to the shelf generation they were built for.

The Synfonet range covers SDH add and drop multiplexing and small cross connection at STM-1, STM-4 and STM-16, and it survives today mostly on private networks in transport, utility and public sector use. Nokia developed it, Marconi acquired it in 1999, and neither company supports it now, so every remaining site depends on the secondary market for plug-in units, subracks, power assemblies and fan parts. The suffix after the decimal point identifies the build variant and is not always interchangeable within one base number.
