Alcatel-Lucent 109555516 Metropolis AMU access multiplexer Optical Transmission Module

Alcatel-Lucent 109555516 (AMU MI-14/4) is a main interface card for the Alcatel-Lucent Metropolis AMU access multiplexer, combining two multirate STM-1/STM-4 optical interfaces with two additional STM-1 interfaces on a single board. As a main interface card rather than a simple tributary board, the MI-14/4 carries core SDH transport functions for the shelf, allowing the Metropolis AMU to interconnect into higher-order STM-4 rings as well as STM-1 access links, giving operators flexibility to mix ring and spur topologies from the same platform. This card is used by network operators and field engineers to maintain or repair existing Metropolis AMU deployments where the core SDH interface card has failed, restoring the shelf’s network-facing transport connectivity rather than a single tributary group. Because it is a core, platform-specific main interface card, it is intended for operators already running Metropolis AMU infrastructure who need a confirmed like-for-like replacement matched to their shelf configuration. Tech-Star (UK-based, shipped worldwide) stocks legacy Alcatel-Lucent SDH transmission spares. Enquire to confirm compatibility and current availability.
