電動(dòng)光纖偏振控制器
電動(dòng)偏振控制器是控制單模光纖產(chǎn)生各種偏振態(tài)的一種有效的工具,通過(guò)驅(qū)動(dòng)器提供 4 路直流電壓,電壓在+/-5V 交替變化,用來(lái)動(dòng)態(tài)的控制單模光纖的偏振態(tài).5V 的直流電壓提供給偏振控制器內(nèi)部的光纖擠壓裝置,該裝置會(huì)對(duì)光纖產(chǎn)生超過(guò) 25N 的應(yīng)力,足可以使偏振態(tài)在 360 度的范圍內(nèi)變化.電動(dòng)偏振控制器內(nèi)部的3個(gè)光纖擠壓裝置分別和相鄰的光纖擠壓裝置有 45 度角的偏差
產(chǎn)品特點(diǎn): ● 插入損耗可忽略 ● 回波反射可忽略 ● 偏振相關(guān)損耗可忽略 ● >100Hz 的響應(yīng)速度 ● 偏振態(tài)連續(xù)可控 ● 低電壓驅(qū)動(dòng)應(yīng)用領(lǐng)域:擾偏或者偏振控制 ● 偏振穩(wěn)定 ● 緩和偏振模式色散(PMD) ● 緩和偏振相關(guān)損耗(PDL) ● PDL 和 PMD 測(cè)量系統(tǒng) |
工作溫度(多種溫度級(jí)別可選):
● 商用級(jí):0~+7度
● 擴(kuò)展級(jí):-10~+80度
● 工業(yè)級(jí):-40~+85度
