Alcatel-Lucent 109281840007 1655 AMU access multiplexer Optical Transmission Module

Alcatel-Lucent 109281840007 is the Multi-STM Main Board for the Alcatel-Lucent 1655 AMU access multiplexer, an SDH transmission board offering a mixed interface capacity of 12 x STM-1e (electrical), 16 x STM-1o (optical) and 4 x STM-4 ports on a single card. As the main board of the 1655 AMU shelf, it carries the SDH cross-connect and transport functions that allow the platform to aggregate lower-order tributary traffic and interconnect it into the SDH ring or point-to-point network, making it one of the core active components of the system rather than a simple interface card. This part is used by network operators and telecom field engineers to maintain or repair existing 1655 AMU deployments where the main SDH processing board has failed or needs replacement, restoring the shelf transport capability rather than a single tributary port group. Because it is a core, platform-specific transmission board, it is intended for operators already running 1655 AMU infrastructure who need a confirmed like-for-like replacement. Tech-Star (UK-based, shipped worldwide) stocks legacy Alcatel-Lucent SDH transmission spares. Enquire to confirm shelf revision and current availability.
