Abstract
A link status measurement method includes: A first OLT sends first indication information to a first ONU through a first port. The first ONU is one of at least one ONU included in a PON, and the first indication information indicates a measurement window for measuring the first ONU. The first OLT obtains quality of a signal corresponding to the first ONU. The quality of the signal is quality of a signal received by a second port on a second OLT from a first PON channel in a measurement window, and the first PON channel is a channel carried on a link between the second port and the first ONU. The first OLT determines a status of a backbone link based on quality of a signal corresponding to each ONU in the PON. The backbone link is a common part of a link from the second port to each ONU.
