Tuning of receiver components in an optical line terminal

A method comprising, during a time window:

• initiating a tuning cycle by starting the tuning of one or more burst receiver components within an optical line terminal, OLT;
• wherein the OLT is configured to communicate in a point-to-multipoint optical network with optical network units, ONUs;
• wherein upstream burst signals originating from one or more ONUs can be received by the OLT at any time during the time window;
• if detecting a burst signal within a first period, extending the tuning cycle by a second period to continue the tuning of the one or more burst receiver components;
• if detecting at least one pattern within the burst signal within the second period, extending the tuning cycle to decode the burst signal;
• and
• else, terminating the tuning cycle by initiating a next tuning cycle.

A non-transitory computer-readable medium storing instruction, which when executed by a processor cause an apparatus including the processor to perform:

• during a time window, initiating a tuning cycle by starting the tuning of one or more burst receiver components within an optical line terminal, OLT;
• wherein the OLT is configured to communicate in a point-to-multipoint optical network with optical network units, ONUs;
• wherein upstream burst signals originating from one or more ONUs are unallocated during the time window;
• if detecting a burst signal within a first period, extending the tuning cycle by a second period to continue the tuning of the one or more burst receiver components;
• if detecting at least one pattern within the burst signal within the second period, extending the tuning cycle to decode the burst signal;
• and
• else, terminating the tuning cycle by initiating a next tuning cycle.
