Abstract

The invention provides an all-optical serial-parallel conversion system based on a wavelength division multiplexing technology. Multi-wavelength light is combined and shunted through the wavelength division multiplexing technology, conversion from a high-speed serial-parallel signal to a low-speed parallel signal is achieved by controlling on-off of a high-speed optical switch, a low-speed parallel non-return-to-zero code electric signal is obtained based on the code pattern conversion technology, and picosecond-magnitude all-optical serial-parallel conversion is achieved. The control signal characteristics and the switching speed of the optical switch are controlled; the all-optical serial-to-parallel conversion with a transparent code pattern is realized, the all-optical serial-to-parallel conversion without cache is realized, the time domain delay of a wavelength division multiplexing optical signal is realized by utilizing the dispersion time domain dispersion delay characteristic,the serial-to-parallel conversion is carried out through the high-speed optical switch switching unit, and a non-return-to-zero code electric signal is obtained through the code pattern conversion unit.

Description

technical field [0001] The invention belongs to the field of optical signal processing, and in particular relates to an all-optical serial-to-parallel conversion system based on wavelength division multiplexing technology. Background technique [0002] With the rapid development of transmission technology, single-fiber transmission capacity will be significantly improved. However, the transmission and switching of high-quality data services is not only expensive in the multi-layer network structure scheme, but also must undergo electro-optical conversion at the transit node, which cannot make full use of the underlying broadband resources and powerful wavelength routing capabilities. Using high-speed optical switching technology, the signal is directly processed in the optical domain. Compared with the traditional electrical signal processing technology based on optoelectronics, the advantages of optical signal processing technology mainly include: it can process multi-wave...
