Colorless and Directionless Coherent WDM-PON Architecture with Extended Star Topology Using a Self-healing for Bidirectional Link Protection

The redundant optical link protection is the most popular technology by which we advance the reliability of Ethernet Passive Optical Networking (EPON) in power communication network, and self-healing sooner the network better. Through optical link state monitoring technology, we can start the protection switching immediately. Through optical network unit(ONU) pre-registration technology, we can shorten the self-healing time. Moreover, everything is occur on ONU, and then it would simplify the process.

Link Protection

A WDM optical access network architecture based on double-fiber-tangent rings is proposed. With the proposed architecture, both data convergence and link protection can be realized. OLT and RNs can automatically switch to protection mode to overcome fiber failure occurring no matter in both primary ring (PR) and sub-ring (SR). The RNs designed as tangent points can realize wavelengths adding and dropping between PR and SR, and they also can realize network expansion through adding more wavelengths. In addition to this, the design of double-fiber ring can better the survivability and self-healing ability of the network.
