Abstract
Disclosed are a method and device for transmitting optical signals. The method comprises: if there is Raman crosstalk between a first optical network system and a coexistence system, an upstream wavelength band of the first optical network system is set outside a range with an upstream wavelength band of the coexistence system being a center and with an impact intensity of the Raman crosstalk being a radius, and a downstream wavelength band of the first optical network system is set outside a range with the downstream wavelength band of the coexistence system being a center and with the impact intensity of the Raman crosstalk being a radius; and optical signals are transmitted by using the upstream wavelength band of the first optical network system and the downstream wavelength band of the first optical network system. The disclosure can avoid interference and improve signal quality.
