A transponder is a physical layer device whose task is to map traffic from the client port to the line port, and vice versa.
3R signal regeneration enables OEO (Optical-Electrical-Optical) regeneration, which improves transmission quality and stability, especially over longer distances.
Demarcation point allows you to define the boundary of responsibility and facilitates diagnostics between devices in the data center and the transmission system. From the transponder level, it is possible to monitor the transmission and reception power for all services.
Preservation of original modules in end devices The transponder can act as a signal “coloring” device, allowing the use of original modules in switches or routers, while using others – e.g., DWDM – in the transponder itself.
