Abstract

An optical module with an overhead-modulation function, and a data transmission system. The optical module comprises: a processing unit (10), an emitting unit (20), and a receiving unit (30), wherein the processing unit (10) is used for generating a first overhead-modulation signal; the emitting unit (20) is used for sending the first overhead-modulation signal and a first primary service signal to the next optical module; and the receiving unit (30) is used for receiving from the previous optical module a second primary service signal and a second overhead-modulation signal generated by the previous optical module. The emitting unit (20) comprises a loading circuit (21), and the receiving unit (30) comprises a sampling amplification circuit (31). An output end of the processing unit (10) is connected to an input end of the loading circuit (21), and an input end of the processing unit (10) is connected to an output end of the sampling amplification circuit (31); the loading circuit (21) is used for loading the first overhead-modulation signal into the primary service signal, so that the first overhead-modulation signal is transmitted along with the first primary service signal; and the sampling amplification circuit (31) is used for extracting the second overhead-modulation signal, filtering and amplifying the second overhead-modulation signal and then transmitting same to the processing unit (10). Thus, the present application facilitates the supervision over a remote module.
