NEC X7139E1-V02BB: Card for the NEC FOTS/FD-1840 optical transmission platform.

The NEC X7139E1-V02BB is a card for NEC’s FOTS (Fiber Optic Transmission System) FD-1840-series optical transmission platform, identified by its part-number convention as belonging to the same X-prefixed card family as NEC’s documented FOTS multiplexer, demultiplexer, alarm-interface and alarm-control-unit cards (X1830A, X1831A, X1832B, X6716A, X6717A, X6718A). FOTS/FD-1840 systems are SDH/PDH-generation fibre-optic transmission equipment used to multiplex and carry voice, data and alarm signalling over optical fibre links, and the platform’s card-cage design accepts a range of interface, processor and control cards to configure each terminal for its specific role in the network. FOTS/FD-1840 equipment remains in service in a number of established transmission networks, and genuine NEC spares are a routine requirement for maintaining these deployments. Precise on-card function can vary by exact card type and revision, so specifiers should confirm compatibility against their specific FOTS configuration before ordering. Tech-Star (UK-based, shipped worldwide) stocks tested NEC FOTS cards to support ongoing network maintenance. Please contact our sales team to confirm exact compatibility and for current stock and pricing.
