CWDM 1270/1,1290/1......1610/1nm每個波長信道間隔20nm;
DWDM CH17~CH61 L62~L09 50GHZ信道間隔約0.4nm、100GHZ信道間隔約0.8nm、200GHZ信道間隔約1.6nm.
封裝形式:SFP、SFP+、XFP、SFP28等
用途:多用于光纖擴容線路測
特點:具有傳輸距離遠、帶寬容量大、節(jié)約光纖資源
什么是灰(白)光模塊?沒有特定的標準波長光模塊.
常用的有多模850nm ;單模1310nm、1490nm、1550nm等,波長范圍較寬一般在±40nm左右.
封裝形式:與彩光模塊相同
用途:多用于機房客戶(用戶)測以
特點:功耗小、適用近距離傳輸
光器件:
發(fā)射器件使用高性能EML(電吸收調(diào)制激光器)電吸收調(diào)制器(EAM)與DFB激光器(LD)的集成器件,具有體積小、波長啁啾低等優(yōu)點。
接收器件使用APD(雪崩二極管)是具有內(nèi)增益的一種光伏器件,利用光生載流子在場內(nèi)的定向運動產(chǎn)生雪崩效應(yīng),從而獲得光電流的增益;具有封裝體積小、靈敏度高等優(yōu)點。
芯片方案
光模塊采用進口激光器驅(qū)動芯片GN2044S配合TEC驅(qū)動ADN8834,能夠?qū)l(fā)射激光器波長鎖定在0.1nm以內(nèi)長時間工作不偏移;接收升壓電路采用進口芯片I7990長時間工作穩(wěn)定輸出電壓供電.
外殼
采用鋅合金材料以及芯片部位拉伸凸臺設(shè)計,配合使用PG80A進口導(dǎo)熱材料充分將IC和器件熱量導(dǎo)出模塊外殼。
優(yōu)勢:自主研發(fā),進口芯片,進口光引擎,進口測試設(shè)備,實纖傳輸測試,全面兼容市場主流交換機以及光傳輸設(shè)備.
