Marconi/Nokia T30023.01 Nokia Synfonet / Marconi SDH transmission Optical Transmission Module

The Marconi/Nokia T30023.01 is a Synfonet STM-4 optical interface unit. The T30023 group is catalogued as the platform’s STM-4 line unit, working at 622 Mbit/s and giving a Synfonet node four times the aggregate capacity of an STM-1 span. Published records cover the short haul 1300 nm builds in this group; the exact optics on this particular suffix are not something we will state from the code alone, so tell us the release you are matching and we will read the label on the unit we hold.

Nokia Synfonet is early SDH, carried into the Marconi portfolio after the 1999 acquisition, and it is still running on private and utility networks where the ring was built once and then maintained rather than replaced. The platform spans STM-1 through STM-16 with 64 kbit/s cross connection, and every node is built up from interface units, control and timing, service and management cards, power feeds and mechanical parts. Spares are sourced by exact code, because the number after the decimal point decides which release and which optical variant a unit will work with.

Send us the platform details, or a photograph of the board label you are matching, and we will verify the item physically before despatch.
