Optimum of the LD Interface Circuit in Transceiver Module

In high-speed Transceiver module,the LD interface circuit is the keylinks determining whether a module can achieve its performance targets.Therefore,according to the characteristics of semiconductor laser,in the paper an alternating current coupling interface circuit has been introduced,which can optimize the design of the interface circuit through slightly adjusting electronic element when first measurement is made in the Transceiver module.
