STATION-SIDE OPTICAL NETWORK TERMINAL APPARATUS, SUBSCRIBER-SIDE OPTICAL NETWORK TERMINAL APPARATUS, AND OPTICAL COMMUNICATION SYSTEM |
摘要 |
While continuously providing a service in an existing optical communication system, a service at another communication speed is realized at low cost. For this reason, a station-side optical network terminal apparatus is configured so that to one light-emitting unit connected are a first processing unit that performs a process to output an optical signal at one communication speed by the light-emitting unit and a second processing unit that performs a process to output an optical signal at another communication speed by the light-emitting unit.
