Abstract: This application discloses a communication method, an optical line terminal, and an optical network unit in a passive optical network system. The PON system includes an OLT and at least one ONU, and the method includes: receiving, by the OLT, a first message that is sent by a first ONU in the at least one ONU through a first upstream channel; determining a first round trip time (RTT) of the first ONU based on a receiving moment of the first message; determining a time window based on the first RTT; sending first indication information to the first ONU through a downstream channel, where the first indication information includes the time window; receiving a second message that is sent by the first ONU through a second upstream channel within the time window; and determining a second RTT of the first ONU based on a receiving moment of the second message.

Abstract: An optical network termination (ONT) receives an uplink message, the ONT includes a virtual local area network (VLAN) tagging operation configuration data managed entity (ME) with a VLAN tagging operation table, and each entry of the VLAN tagging operation table includes a group of operation value fields and a group of filter value fields including an outer layer VLAN priority filter value, an outer layer VID filter value, an inner layer VLAN priority filter value and an inner layer VID filter value. The ONT filters the received uplink message according to a characteristic value of the received uplink message by using at least one of the above values in a corresponding entry of the VLAN tagging operation table. The ONT performs a VLAN tagging operation for the filtered o uplink message.

Abstract: The present application provides an optical port auto-negotiation method, including: a: selecting a downstream to-be-received wavelength; b: listening to a downstream message on the selected downstream to-be-received wavelength, performing c if a wavelength idle message is received, and returning to a if no wavelength idle message is received within a specified or fixed time, where the wavelength idle message is used to identify that the wavelength is not occupied or not allocated; c: sending a wavelength application message on an upstream wavelength, performing d if a wavelength grant message is received in a downstream direction; otherwise, going back to a or b, where the wavelength application message is used to identify a request for allocation of the wavelength, and the wavelength grant message is used to identify acknowledgment of wavelength allocation; and d: setting an optical port auto-negotiation success flag bit. The present application further provides an optical module.
