摘要： Embodiments of the present invention disclose an optical signal transmission method, apparatus, and system. The apparatus includes a short wavelength division multiplexer, a signal processor, a first linear driver, a second linear driver, a first transmitter, and a second transmitter. The signal processor is configured to perform bit rate allocation and code pattern modulation on a received binary signal, to obtain a first electrical signal to be sent to the first linear driver and a second electrical signal to be sent to the second linear driver. It can be learnt that, by implementing the embodiments of the present invention, a quantity of wavelengths transmitted in a multimode optical fiber can be reduced by performing bit rate allocation on a binary signal, thereby reducing interference between channels in the optical fiber for optical signal transmission.

摘要： A method for detecting an MPI noise problem. The method includes: receiving a first signal, where the first signal includes a service signal sent by a sending device and an MPI noise signal generated by an MPI noise generator, and the MPI noise generator is disposed between the sending device and a receiving device of the service signal; determining whether a packet loss occurs in the service signal; and when a packet loss occurs in the service signal, determining that there is an MPI noise problem in an optical fiber link between the sending device and the receiving device. Therefore, when a packet loss occurs in a service signal that passes through an optical fiber link between a transmit end and a receive end, it can be determined that there is an MPI noise problem in the optical fiber link.

摘要： The present disclosure relates to a verification code obtaining method. In one example method, a verification code obtaining request is sent by an application to a server. The application is installed on a terminal. Applications installed on the terminal further include an input method application and a Short Message Service (SMS) message application. An SMS message that includes a verification code and that is sent by the server is received by the SMS message application. The verification code in the SMS message is read by the input method application. The terminal does not allow an application other than the input method application and the SMS message application to read an SMS message in the terminal.
