automatic power control

基本解釋

The APC(Automatic Power Control)of semiconductor lasers is an important issue in the practical fiber communication.
半導(dǎo)體激光器的自動(dòng)功率控制（APC）是光纖通信實(shí)用化過(guò)程中提出來(lái)的重要課題之一。
An economical and practical laser diode (LD) driver was designed. The driver adopted two kinds of control modes which are automatic current control (ACC) and automatic power control (APC).
設(shè)計(jì)了一種經(jīng)濟(jì)實(shí)用的半導(dǎo)體激光器驅(qū)動(dòng)電源，具有自動(dòng)電流控制（ACC）和自動(dòng)功率控制（APC）兩種控制方式。
But to perfect the system performance , some accessorial circuits are necessary , such as automatic power control circuit , automatic temperature control circuit and protective circuit etc .
為了完善通信系統(tǒng)的性能，除了主干電路外，還必須加入一些附加電路，如自動(dòng)功率控制電路、自動(dòng)溫度控制電路和保護(hù)電路等等。
