Fiber Identification below an Optical Splitter with ONU Upstream Light Signals

摘要

We propose a fiber identification technique that uses a specific Ethernet media access control (MAC) address contained in the upstream light signals of an optical network unit (ONU) for GE-PON. To realize the proposed system, we developed an approach that prevents a fiber bend from halting communication between an optical line terminal (OLT) and an ONU and that displays the MAC address below the optical splitter. We manufactured a prototype and confirmed its efficacy.
