LINK ESTABLISHMENT METHOD FOR MULTI-WAVELENGTH PASSIVE OPTICAL NETWORK SYSTEM

摘要

Provided is a method of establishing a link between service provider equipment and subscriber equipment in a multi-wavelength passive optical network system. The method of establishing a link includes acquiring information about a wavelength plan of allocated wavelengths in the MW PON system; transmitting a first signal wavelength initialization request signal on a first upstream wavelength from physical layer to the service provider equipment; waiting for a response from the service provider equipment for a predetermined time interval after transmitting the first signal wavelength initialization request signal; and in response to failing to receive a response to the first signal-wavelength initialization request signal within the predetermined time interval, transmitting a second signal wavelength initialization request signal on a second upstream wavelength to the service provider equipment after the waiting.
