Claim 4:
5. A first optical module used in a first network device, the first optical module comprising:
a processor, configured to:
extract a first indication signal carried in a first packet transmitted to a first circuit of the first optical module;
extract a second indication signal carried in the first packet transmitted to a second circuit of the first optical module;
determine a first delay based on the first indication signal and the second indication signal, wherein the first delay comprises a delay generated when the first packet is transmitted in the first optical module; and
