PWDM基于成熟的薄膜濾波技術設計,具有平坦的通道帶寬和高隔離度,具有低插入及高環(huán)境穩(wěn)定性和可靠性等特點,使用于光纖放大器,有限電視和FTTH應用領域。
產(chǎn)品特性
● 較低的插入損耗,使PWDM器件運用在波分復用系統(tǒng)里面時擁有較低的信號衰減,從而降低對信號發(fā)射器的功率要求。
● 較高隔離度值,使PWDM器件運用在波分復用系統(tǒng)里面多信號傳輸時進行充分的信號隔離,有效防止信號之間相互串擾導致傳輸信號失真。
● 減少系統(tǒng)內(nèi)的功率波動,從而降低系統(tǒng)的比特錯誤率。
● 符合 Telcordia GR-1221/1209核心標準
