ALCATEL 3DB02136AA 9600 LSY long-haul microwave radio Microwave Radio

The 3DB02136AA is an Alcatel 9600 LSY long-haul STM-1 modem unit (documented part designation ‘MODEM LH-STM1-1WST’), confirmed by independent Alcatel-Lucent parts resellers as a card for the Alcatel 9600 LSY microwave transmission system. The 9600 LSY is a long-haul digital microwave radio platform used to carry SDH/SONET traffic at STM-1 (155 Mbit/s) rates over point-to-point microwave links, typically deployed by network operators to backhaul traffic across routes where fibre is impractical or as a resilient alternate path alongside fibre. This modem card handles the modulation/demodulation of the STM-1 signal for transmission over the radio link, sitting within the indoor unit of the 9600 LSY system alongside interface and control cards. Operators still running legacy 9600 LSY microwave links keep this class of modem card as a maintenance spare, since replacement stock for this generation of Alcatel-Lucent microwave equipment has become scarce as the platform ages out of active production. Tech-Star (UK-based, shipped worldwide) supplies this as a tested spare. Get in touch with our team to confirm compatibility with your specific 9600 LSY configuration before ordering.
