Abstract
A wavelength tuning method and a related device, the method including receiving, by a remote optical module, a wavelength control signal from a central office terminal, where the wavelength control signal indicates a target wavelength tuned by the remote optical module, and where the wavelength control signal is loaded into a first optical service signal in a pilot tone manner, and tuning, by the remote optical module, an operating wavelength of the remote optical module based on the wavelength control signal
Claims20
A wavelength tuning method, comprising:
- receiving, by a remote optical module, a wavelength control signal from a central office terminal, wherein the wavelength control signal indicates a target wavelength tuned by the remote optical module, and wherein the wavelength control signal is loaded into a first optical service signal in a pilot tone manner;
- and
- tuning, by the remote optical module, an operating wavelength of the remote optical module based on the wavelength control signal.
A wavelength tuning method, comprising:
- sending, by a central office terminal, in response to an operating wavelength of a remote optical module being beyond a target wavelength range, a wavelength control signal to the remote optical module, wherein the wavelength control signal indicates a target wavelength tuned by the remote optical module, and wherein the wavelength control signal is loaded into a first optical service signal in a pilot tone manner.
An optical module, comprising:
- a receiver, configured to receive a wavelength control signal from a central office terminal, wherein the wavelength control signal indicates a target wavelength tuned by the optical module, and wherein the wavelength control signal is loaded into a first optical service signal in a pilot tone manner;
- and
- a control unit, configured to tune an operating wavelength of the optical module based on the wavelength control signal.
