Marconi 02HAT00224AAD optical transport Optical Transmission Module

The Marconi 02HAT00224AAD is a dual 10G NRZ transponder card for Marconi optical transport equipment, carrying two 10G channels on one card. A transponder converts a client signal to a wavelength the transport system can carry, and a dual card does that twice in a single slot, which is how a shelf is filled out without running out of physical space as a site grows. NRZ line coding places it in the generation before coherent transmission, so it is matched to shelves and wavelength plans of that era. Marconi’s transmission business passed to Ericsson in 2006, which is why parts from this range appear under both names. Confirm the shelf and the channel plan your system runs before ordering. Tech-Star (UK-based, shipped worldwide) supplies optical transport components for ongoing maintenance projects.
