Data receiving device of parallel optical inter-connected system based on programmable device and method thereof

Abstract

The invention relates to a data receiving device of a parallel optical inter-connected system based on a programmable device and a method thereof, in particular to a receiving device of an ultra-short distance 12-path parallel optical inter-connected system of 40 Gbps and a method thereof. The device comprises receiving / sending serial-parallel / parallel-serial conversion circuits, a frame synchronous circuit, a channel alignment circuit, 12-path to 16-path mapping circuits, a channel resetting circuit and a skewing-removing channel generating circuit. The method comprises the following steps: firstly, the 12-path receiving serial-parallel conversion circuit converts received high-speed data to low-speed parallel data and recovers corresponding clocks, the frame synchronous circuit carries out the frame synchronization for received code flows with a disturbed order while providing a frame head indicating signal of each path for the frame alignment of channel data so as to convert into 16-path data; 16-path data consistent with original sending data cam be output by the channel alignment circuit, the reset data is output to the skewing-removing channel generating circuit to generate a skewing-removing channel, and generated 17-path low-speed data is converted by the sending parallel-serial conversion circuits to 17-path high-speed serial signals to be output.

Description

technical field [0001] The invention relates to a receiving device and method of a parallel optical interconnection system based on programmable devices, in particular to a receiving device and method of a 12-way parallel 40Gbps very short-distance parallel optical interconnection system. [0002] Background technique [0003] As the amount of data transmitted in the communication system continues to grow, more and more devices are concentrated in the same computer room. Whether in the central computer room or inside the equipment, the data transmission rate generally exceeds 10Gb / s . For this kind of high-speed data transmission in a short distance, electrical connection is no longer applicable, and the performance provided by the serial synchronous optical transmission network system applied to the long-distance backbone network is much higher than this demand, and the cost is relatively low. expensive. To this end, the Optical Internetworking Forum (OIF, Optical Interne...
