PWDM基于成熟的薄膜濾波技術(shù)設(shè)計(jì),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(diǎn),使用于光纖放大器,有限電視和FTTH應(yīng)用領(lǐng)域。
產(chǎn)品特性
● 較低的插入損耗,使PWDM器件運(yùn)用在波分復(fù)用系統(tǒng)里面時(shí)擁有較低的信號(hào)衰減,從而降低對(duì)信號(hào)發(fā)射器的功率要求。
● 較高隔離度值,使PWDM器件運(yùn)用在波分復(fù)用系統(tǒng)里面多信號(hào)傳輸時(shí)進(jìn)行充分的信號(hào)隔離,有效防止信號(hào)之間相互串?dāng)_導(dǎo)致傳輸信號(hào)失真。
● 減少系統(tǒng)內(nèi)的功率波動(dòng),從而降低系統(tǒng)的比特錯(cuò)誤率。
● 符合 Telcordia GR-1221/1209核心標(biāo)準(zhǔn)
