The invention relates to the field of optical signal transmission, and discloses a method for adjusting the optical power, and an optical module. In the scheme, a first optical module obtains the optical power of a received optical signal transmitted by a second optical module. The first optical module generates return information for indicating the adjustment of an attenuator at the side of the second optical module according to the obtained optical power of the optical signal. After being adjusted, the attenuator can adjust the optical power of the optical signal which is received by the first optical module and transmitted by the second optical module. The first optical module enables the generated return information to be transmitted to the second optical module. Therefore, there is no need of a person to obtain the optical power of the optical signal received by the first optical module on site and to adjust the attenuator on site, thereby ironing out the defect that the efficiency of adjusting the optical power of the optical signal received by an optical module is low in the prior art.
Description
technical field [0001] The invention relates to the field of optical signal transmission, in particular to a method for adjusting optical power and an optical module. Background technique [0002] With the continuous development of science and technology, electronic technology has also developed rapidly, and there are more and more types of electronic products, and people have also enjoyed various conveniences brought by the development of science and technology. Now people can enjoy the comfortable life brought by the development of science and technology through various types of equipment. For example, optical fiber communication technology has become one of the main information transmission technologies due to its huge transmission capacity, extremely low transmission attenuation, anti-electromagnetic interference, small channel crosstalk and good confidentiality, which has greatly promoted the development of modern information technology. Social development. [0003] T...
