Data processing method and device

Data processing device, the device is realized through a wire clamp (100). The wire clamp comprises a wire clamp body and a fixed part, a first processing module (101), wherein the determining module(S201) is used for determining a logic interface corresponding to a first optical serial signal stream according to a corresponding relationship between the first optical serial signal stream and thelogic interface; wherein the bandwidth of the logic interface is configured to be a first bandwidth, the logic interface corresponds to a first optical interface, and the first optical interface corresponds to one optical fiber or a channel used for transmitting an optical signal of one wavelength in one optical fiber; the second processing module (102) is used for determining the first optical interface corresponding to the logic interface according to the corresponding relationship between the logic interface and the first optical interface and the logic interface determined by the first processing module (S202); and
