Nws yog txhim kho Si avalanche photodiode module nrog pre-amplification Circuit Court uas ua rau tsis muaj zog tam sim no lub teeb liab yuav tsum tau amplified thiab hloov mus rau hauv voltage teeb liab kom ua tiav cov txheej txheem hloov dua siab tshiab ntawm photon-photoelectric-cim amplification.
