Marconi/Nokia T30431.01 Nokia Synfonet / Marconi SDH transmission Optical Transmission Module

Marconi/Nokia T30431.01 has no functional description on our record. It sits immediately after the documented STM-16 subrack in Nokia’s numbering, which is suggestive of shelf level hardware, but a neighbouring code is a hint and not a source. We would rather tell you that the unit type is unconfirmed than publish an assumption. Give us the machine or shelf you are working on and we will match the physical item to it.

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.

Give us the system details or a picture of the part label and we will physically check the match before despatch. Tech-Star is UK-based and ships worldwide. Please contact our sales team for current availability and pricing.
