METHOD, APPARATUS, SYSTEM AND COMPUTER PROGRAM PRODUCT FOR IDENTIFYING FAILING OR FAILED OPTICAL NETWORK TERMINAL(S) ON AN OPTICAL DISTRIBUTION NETWORK

摘要

An error in a passive optical network is identified by communicating to an optical network terminal on the passive optical network a request to transmit a response signal at a predetermined power level, receiving the response signal in response to the request, and measuring a power level of the response signal. A predetermined channel power level is compared to the power level of the response signal and a status of the optical network terminal is determined based on the result of the comparison.
