Embodiment

Further illustrate the utility model below in conjunction with accompanying drawing how to realize.

As shown in Figure 1, a kind of optical fiber switch supporting multiple speed FC agreement, comprising: the pcb board of FPGA high-speed transceiver, flash memory, support flank speed 16Gbps transfer of data, low rate SFP photoelectric conversion module and two-forty SFP photoelectric conversion module,

Described flash memory is for storing the fpga logic of different editions, and flash memory is used for FPGA high-speed transceiver and extracts the Different Logic stored in FLASH and load,

Described low rate SFP photoelectric conversion module and two-forty SFP photoelectric conversion module are used for mutually changing by the light signal come from external reception with from the signal of telecommunication that the reception of FPGA high-speed transceiver comes,

Described FPGA high-speed transceiver supports the FC agreement of flank speed 16Gbps, for extracting the Different Logic stored in FLASH and loading, drives the SFP photoelectric conversion module of corresponding selected speed and carries out signal of telecommunication transmitting-receiving with SFP photoelectric conversion module,

As shown in Fig. 2-Fig. 3, first select to support that the FPGA device of 16Gbps speed FC agreement is as FC data switch engine, according to the logic loading procedure of FPGA, design multi version logic adaptive allocation.Selected by the version of FPGA holding wire to be connected to the highest two of the address wire of configuration FLASH, subregion is carried out to Flash, stores the logic of different editions respectively.And selected by version holding wire be connected to the panel place of switch and provide by-pass cock, be used for arranging the speed that user wants.When switch powers on, select signal automatically to load the logic of special speed according to version, form the switching engine of special speed.In order to meet the electric signal transmission of flank speed, the FC switch pcb board of multi tate must support the transfer of data of 16Gbps, suitable sheet material must be selected for this reason, optimize high-speed differential signal cabling, ensure that the transmission of the signal of telecommunication of flank speed meets the loss requirement of 16Gbps signal, form the electrical signal paths of 16Gbps transfer of data.Current SFP optical-electric module is very ripe, and for adapting to demand of the present utility model, select two kinds of SFP photoelectric conversion modules, one is low speed SFP optical-electric module, and speed may be selected to be 1G, 2G self adaptation and 2G, 4G self adaptation; One is high speed sfp photoelectric conversion module, and speed may be selected to be 8G and 16G.The SFP photoelectric conversion module of configuration different rates, forms the opto-electronic conversion data transmission channel supporting different rates.End user can according to the selector switch on panel, and arrange different speed, FPGA loads respective logic automatically, forms the FC switch supporting different rates.
