Cov cuab yeej yog silicon avalanche photodiode module nrog plaub qhov zoo ib yam, nrog rau lub hauv paus preamplifier Circuit Court, uas tuaj yeem ua kom lub zog tsis muaj zog tam sim no thiab hloov nws mus rau hauv qhov hluav taws xob teeb liab tso tawm, paub txog qhov "optical-electrical-signal amplification" conversion process.
