Title:
TRANSMITTING DEVICE, RECEIVING DEVICE, OPTICAL TRANSMISSION SYSTEM, AND OPTICAL POWER CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2018/187930
Kind Code:
A1
Abstract:
The present application relates to the technical field of optical communications, and provided thereby are a transmitting device, a receiving device, an optical transmission system, and an optical power control method, the transmitting device comprising: a wave combining unit and an optical power adjusting unit; the wave combining unit is used for transmitting at least two communication optical waves to a fiber channel and for transmitting or receiving at least two detection optical waves by means of the fiber channel; the optical power adjusting unit is used for acquiring a power control instruction, which is generated according to power change information between the at least two detection optical waves, and performing optical power amplification and/or attenuation on at least one communication optical wave of the at least two communication optical waves according to the power control instruction. With the present application, the effect of stimulated Raman scattering (SRS) effect on the optical power of the communication optical waves may be quickly detected by means of the power change information between the at least two detection optical waves, so that the optical power adjustment unit dynamically adjusts the optical power of the communication optical wave according to the power control instruction, thereby reducing or eliminating the effect of SRS effect on the optical power.
