Marconi 02HAT00127AAD optical transport Optical Transmission Module

The Marconi 02HAT00127AAD is a 10G NRZ transponder card for Marconi optical transport equipment. A transponder takes a client signal and converts it to a wavelength the transport system can carry across the network, which is the function that lets ordinary equipment hand traffic to a long haul optical line without needing optics of its own. At 10G with NRZ line coding this belongs to the generation before coherent transmission, so it is matched to shelves and wavelength plans of that era rather than to later equipment. Marconi’s transmission business passed to Ericsson in 2006, which is why parts from this range appear under both names. Confirm the shelf, the wavelength plan and the client rate before ordering. Tech-Star (UK-based, shipped worldwide) supplies optical transport components for ongoing maintenance projects.
