Abstract:
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.

Claim (Index 2):
The apparatus according to  claim 1 , wherein the signal processor comprises a serializer/deserializer, a first 4 pulse amplitude modulation (PAM4) encoder, a second PAM4 encoder, a first transmitter digital signal processor, and a second transmitter digital signal processor, wherein:\n the serializer/deserializer is configured to perform bit rate allocation on the binary signal according to a proportion, to obtain a first non-return to zero (NRZ) signal, a second NRZ signal, a third NRZ signal, and a fourth NRZ signal, wherein each of bit rates of the first NRZ signal and the second NRZ signal is a second bit rate, each of bit rates of the third NRZ signal and the fourth NRZ signal is a third bit rate, and the proportion is equal to a value obtained by dividing the second bit rate by the third bit rate; the first PAM4 encoder is configured to perform PAM4 encoding on the first NRZ signal and the second NRZ signal to obtain a fifth electrical signal; the second PAM4 encoder is configured to perform PAM4 encoding on the third NRZ signal and the fourth NRZ signal to obtain a sixth electrical signal; the first transmitter digital signal processor is configured to perform an equalization operation on the fifth electrical signal, to obtain the first electrical signal; and the second transmitter digital signal processor is configured to perform an equalization operation on the sixth electrical signal, to obtain the second electrical signal.
