This paper presents the design and development of a bit rate adaptive 3R O/E/O transponder, which accomplishes full data rate and protocol transparency from 30Mb/s to 2.5Gb/s by signal processing in electric domain. This transponder makes use of chipsets that perform clock recovery in continual bit rate ranges, that is, software configuration and provision are achieved for continual bit rates. The measuring results presented in this paper show us that a good bit rate-adaptive capability and a good BER performance can be achieved, which indicates the commercial application is feasible. This paper also discusses the architecture extension and application of this transponder toward an intelligent photoelectronic gateway for the future application in wide area optical networking. Transition from research laboratory into the marketplace is also undertaken now.
