An implementation of optical transponder and media converter unit for speeds up to 2.5 Gbps

The paper presents the implementation of protocol agnostic optical transponder and media converter unit for speeds up to 2.5 Gbps. Detailed depiction of the implementation is given, including hardware design issues, as well as the signal integrity solutions. In addition, the design implemented in field-programmable gate array (FPGA) chip is discussed. On the other hand, embedded software implementation is explained, as well as the interface to the network management software that executes on PC. Finally, strategy for the verification of the unit functionalities at the end of the development stage is given, and results are presented.
