CEx WDM模塊是針對GPON、XGS-PON、OTDR、RF video和NG-PON2在OLT到ONU傳輸過程中同時存在的情況而設(shè)計的。
產(chǎn)品特性
● 較低的插入損耗,使產(chǎn)品運(yùn)用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。
● 較高的隔離度值,使器件里面多信號傳輸時進(jìn)行充分的信號隔離,有效防止信號之間相互串?dāng)_導(dǎo)致傳輸信號失真。
● 北億纖通 的CEx WDM模塊具有成熟的生產(chǎn)工藝,性能穩(wěn)定可靠,支持-10℃~+70℃ 的惡劣環(huán)境下工作,保證信號的穩(wěn)定傳輸。
● 北億纖通的CEx WDM模塊符合RoHS,滿足TelcordiaGR-1209與GR-1221。

應(yīng)用環(huán)境
讓G/EPON與NG-PON1、NG-PON2系統(tǒng)3種系統(tǒng)共享,需要用到CEx波長共存原件,又稱為Coexistence WDM(共存波分),共存波分要根據(jù)實際情況還選用。
