描述
手動(dòng)可調(diào)濾光器,用于手動(dòng)調(diào)整 1550 nm(C 波段)區(qū)域的中心波長。最大可調(diào)范圍超過 15 nm。該濾波器基于通過精確測微頭壓縮 FBG(光纖布拉格光柵),可實(shí)現(xiàn) 70 pm 的微調(diào)分辨率。
特征
● 手動(dòng)可調(diào)濾光片
● 可調(diào)范圍 > 15 nm
● C 波段可選中心波長手動(dòng)調(diào)節(jié) (1520 – 1570 nm)
● FWHM 可選 0.2 – 0.5 nm
● 微調(diào)分辨率 70 pm
應(yīng)用
● 波長選擇形成寬帶光源。
● 噪聲抑制,例如在 EDFA 放大器和具有可調(diào)波長的傳輸系統(tǒng)中。
● 電信 - WDM 系統(tǒng)中的信道選擇。
● 專為實(shí)驗(yàn)室和測試目的而設(shè)計(jì)。
