摘要： The present invention discloses a data transmission method, an apparatus, and a system. The method includes: receiving, by a mode multiplexer from an input port, a first optical signal transmitted by an optical line terminal; converting, according to a correspondence between an input port of an optical signal and a mode of the optical signal, the received first optical signal into a second optical signal in a mode corresponding to the input port; and multiplexing the second optical signal obtained by means of conversion to a few-mode optical fiber for transmission. This implements big data transmission by increasing a transmission capacity of a single optical fiber, and implements fast expansion of the transmission capacity, thereby improving total bandwidth utilization of a system.

摘要： A method of transmitting digital information over a dispersive optical channel (106) comprises encoding (152) the digital information into a series of data blocks, wherein each block comprises a plurality of substantially orthogonal frequency domain subcarriers, each data block is then divided (154) into at least two frequency bands, each band comprising a plurality of contiguous subcarriers. A frequency/time transformation is then performed (156), in order to form a corresponding plurality of transformed bands, each transformed band comprising a sequence of time domain data samples. A time delay is applied (158) to at least one of the transformed bands relative to at least one other of the transformed bands. The bands are then combined (160) to produce an electrical signal waveform embodying the digital information. Finally, an optical source is modulated (162) using the electrical signal waveform, to produce a corresponding optical signal for transmission over the dispersive optical channel (106). The invention enables a reduction in the duration of guard intervals that may need to be inserted into the transmitted data blocks, in order to avoid received signal degradation due to inter-symbol interference caused by dispersion in the optical channel (106). Transmission overheads may thereby be reduced, resulting in an improvement in transmission efficiency.
