單模光纖收發器簡介

光纖收發器的(de)(de)(de)(de)(de)(de)(de)種(zhong)類也很(hen)(hen)繁雜。光纖(xian)(xian)網(wang)(wang)絡(luo)的(de)(de)(de)(de)(de)(de)(de)發(fa)展成為(wei)(wei)了(le)一(yi)(yi)(yi)個必然的(de)(de)(de)(de)(de)(de)(de)趨勢，故此(ci)現在的(de)(de)(de)(de)(de)(de)(de)企(qi)業(ye)在自身網(wang)(wang)絡(luo)建設(she)時(shi)就直接使用(yong)光纖(xian)(xian)作為(wei)(wei)傳(chuan)輸(shu)(shu)介(jie)質(zhi)(zhi)來建立骨干網(wang)(wang)，還有(you)很(hen)(hen)多企(qi)業(ye)基于(yu)商業(ye)的(de)(de)(de)(de)(de)(de)(de)需要也紛紛升級原有(you)的(de)(de)(de)(de)(de)(de)(de)網(wang)(wang)絡(luo)。但(dan)(dan)是(shi)(shi)出于(yu)資(zi)金、人(ren)力或時(shi)間的(de)(de)(de)(de)(de)(de)(de)考慮，很(hen)(hen)多企(qi)業(ye)用(yong)戶都迫切(qie)需要一(yi)(yi)(yi)種(zhong)廉價(jia)的(de)(de)(de)(de)(de)(de)(de)方案，既能將(jiang)成本降低，同(tong)(tong)時(shi)也讓原有(you)的(de)(de)(de)(de)(de)(de)(de)設(she)備得(de)到最大(da)的(de)(de)(de)(de)(de)(de)(de)保(bao)(bao)值。　所以(yi)(yi)很(hen)(hen)多的(de)(de)(de)(de)(de)(de)(de)企(qi)業(ye)的(de)(de)(de)(de)(de)(de)(de)做法就是(shi)(shi)主干網(wang)(wang)為(wei)(wei)光纖(xian)(xian)，而內部(bu)局域(yu)網(wang)(wang)的(de)(de)(de)(de)(de)(de)(de)傳(chuan)輸(shu)(shu)介(jie)質(zhi)(zhi)一(yi)(yi)(yi)般為(wei)(wei)銅(tong)線、雙(shuang)絞線。但(dan)(dan)如何實現局域(yu)網(wang)(wang)同(tong)(tong)光纖(xian)(xian)主干網(wang)(wang)相連呢？這就需要在不(bu)同(tong)(tong)端口(kou)、不(bu)同(tong)(tong)線形、不(bu)同(tong)(tong)光纖(xian)(xian)間進(jin)行轉換(huan)(huan)并保(bao)(bao)證(zheng)鏈接質(zhi)(zhi)量。光纖(xian)(xian)收(shou)發(fa)器是(shi)(shi)一(yi)(yi)(yi)種(zhong)將(jiang)短距離(li)的(de)(de)(de)(de)(de)(de)(de)雙(shuang)絞線電(dian)信號和長距離(li)的(de)(de)(de)(de)(de)(de)(de)光信號進(jin)行互換(huan)(huan)的(de)(de)(de)(de)(de)(de)(de)以(yi)(yi)太(tai)網(wang)(wang)傳(chuan)輸(shu)(shu)媒體轉換(huan)(huan)單(dan)元，在很(hen)(hen)多地方也被稱之為(wei)(wei)光電(dian)轉換(huan)(huan)器或光纖(xian)(xian)轉換(huan)(huan)器（Fiber Converter）。

簡單的講，光纖收發器一端是接光傳輸系統，另一端（用戶端）出來的是10/100M以太網接口，其主要原理是通過光電耦合來實現的，對信號的編碼格式沒有什么變化。光纖收發器具有提供超低時延的數據傳輸、對網絡協議完全透明、多采用專用ASIC芯片實現數據線速轉發、設備多采用1+1的電源設計等等的優點，支持超寬電源電壓，實現電源保護(hu)和自動切換。同時支(zhi)持超寬(kuan)的工作(zuo)溫(wen)度范圍，支(zhi)持0～120公里齊全的傳輸距離。

單(dan)模收(shou)(shou)(shou)(shou)發器(qi)覆蓋的(de)范圍可以(yi)從20公(gong)里至120公(gong)里。需(xu)要指出的(de)是因(yin)傳輸距離的(de)不(bu)同，光(guang)(guang)纖(xian)收(shou)(shou)(shou)(shou)發器(qi)本身的(de)發射(she)功率(lv)、接收(shou)(shou)(shou)(shou)靈(ling)敏(min)(min)度和(he)使(shi)用(yong)波(bo)長也(ye)會(hui)不(bu)一樣。如(ru)20公(gong)里光(guang)(guang)纖(xian)收(shou)(shou)(shou)(shou)發器(qi)的(de)發射(she)功率(lv)一般在(zai)-15～-7db之間，接收(shou)(shou)(shou)(shou)靈(ling)敏(min)(min)度為-30db，使(shi)用(yong)1310nm的(de)波(bo)長；而120公(gong)里光(guang)(guang)纖(xian)收(shou)(shou)(shou)(shou)發器(qi)的(de)發射(she)功率(lv)多在(zai)-5～0dB之間，接收(shou)(shou)(shou)(shou)靈(ling)敏(min)(min)度為-38dB，使(shi)用(yong)1550nm的(de)波(bo)長。
