| Summary: | 碩士 === 國立交通大學 === 管理學院碩士在職專班資訊管理組 === 96 === We purpose a new protection mechanism and technology for Ring-Architecture Passive Optical Network, the protection mechanism can prevent the Ring-Architecture Passive Optical Network fail and broken. We use the protection technology to recover the fail network and find out the precise broken allocation of the passive optical network.
In this thesis, we purpose a new Ring-Architecture Passive Optical Network. We don’t use any additional new type active optical device in the new the Ring-Architecture Passive Optical Network. We just use 2x2 optical splitter/coupler, and add simple optical device in OLT and ONU to implement the protection mechanism. This new implement provides a protection mechanism for passive optical network and monitor the broken allocation of the passive optical network in real time.
The experiment result demonstrates that, the protection mechanism in Ring-Based Passive Optical Network provides a high fail-over switching speed by merely using low-cost passive components. The proposed mechanism achieves a high performance which is as good as those protection mechanism implemented in high cost.
