Marconi/Nokia T30170.02 Nokia Synfonet / Marconi SDH transmission Optical Transmission Module

The Marconi/Nokia T30170.02 is a Synfonet STM-1 optical interface unit, and this suffix is the one that appears in published reseller catalogues as the short haul 1300 nm build. It terminates a 155 Mbit/s SDH span at the node using optics intended for short reach working. Units of this type are among the more commonly requested Synfonet spares, because STM-1 access rings outlived the higher order parts of the network they were built to feed.

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.
