It has designed a electronic system which receive data from electronic detector of KM 2A though dis-tance optical fiber transmission .KM2 A is a lord array used on a large high altitude air cluster observatory ( LHAASO) .Also do the test to compare the high speed data collecting module integrated in FPGA with the SerDes commercial chip;Test the phase relationship between transmit and recovery clock by two kinds of optical clock transmission , and compare the test result .
