電控光纖衰減器
電控光纖衰減器(EVOA)采用基于MEMs技術(shù)的可調(diào)光衰減器,通過調(diào)整內(nèi)部的MEMS反射鏡角度可以調(diào)節(jié)輸入和輸出光纖之間的衰減系數(shù),它即可以用于控制單模光纖的光功率,也可以工作在輸出光功率鎖定模式下。衰減量大于25 dB,通過面板電位器手動(dòng)旋轉(zhuǎn)或SMA接頭施加外部控制電壓(最大頻率1 kHz),可以連續(xù)調(diào)諧 衰減。輸出功率以mW為單位顯示在前面板上。顯示的輸出光功率默認(rèn)狀態(tài)在1550 nm校準(zhǔn),也可以在EVOA工作波長(zhǎng)范圍內(nèi)進(jìn)行其它波長(zhǎng)的自定義校準(zhǔn)。特有的功率鎖定功能,能夠自動(dòng)穩(wěn)定地輸出功率。只需將EVOA調(diào)節(jié)到所需的功率水平,并按下鎖定按鈕即可,在這種模式非常適合校正長(zhǎng)期測(cè)量中出現(xiàn)的慢速漂移。
