ALCATEL 3AL81289AAAB -Lucent 1660SM O-16ES Optical Transmission Module

The Alcatel-Lucent 3AL81289AAAB is an O-16ES optical port card for the Alcatel-Lucent 1660SM SDH optical transmission platform, a metro and regional transport system supporting speeds up to STM-64. Cards in the 3AL81289 family provide STM-16 optical interfaces for the 1660SM shelf, terminating high-capacity optical line signals and passing traffic to the shelf’s cross-connect matrix. The base part number 3AL81289AA is a confirmed live board in Tech-Star’s own catalogue, already stocked and categorised as an optical transmission module, and this unit shares the same base material code with an AB revision suffix, indicating the same board type and function from a different production batch. STM-16 optical interface cards of this class are a common upgrade or replacement item in 1660SM rings carrying higher-capacity traffic than STM-1/STM-4 tributary levels, and are typically sourced as tested pulls given the platform’s manufacturer end-of-life status for new-build hardware. Tech-Star (UK-based, shipped worldwide) stocks tested Alcatel-Lucent 1660SM optical, matrix and power cards; contact our engineers to confirm the exact revision and optical reach needed for your ring before ordering.
