| Abstract(in English) | In multi-carrier transmission systems, a transponder is composed of a number of optical modules equal to that of sub-carriers. Assuming that each optical module fails at a certain probability, the availability of a transponder decreases in accordance with the increase in the number of optical modules comprising the transponder. In this paper, we clarify promising schemes to improve the availability of multi-carrier transmission systems by comprehensively comparing them. We compare the improvement in availability, consistency with the current standardization, and difficulty in transmission system development based on two major schemes: (a) client traffic is continuously transmitted using only non-failed sub-carriers (Polishing scheme) and (b) the degree of redundancy of optical modules is increased to avoid transponder failure (Pool scheme). As a result, we showed that the Pool scheme is promising since it effectively increases availability with a small amount of additional optical modules and has high consistency with the current standardization and enough feasibility. |
