單模光纖收發器簡介

光纖收發器的(de)(de)種類也很(hen)繁雜。光(guang)(guang)(guang)纖(xian)(xian)(xian)(xian)網(wang)(wang)(wang)絡(luo)的(de)(de)發展成(cheng)為(wei)了一(yi)個必然的(de)(de)趨勢，故此現在(zai)(zai)的(de)(de)企(qi)業(ye)(ye)在(zai)(zai)自身網(wang)(wang)(wang)絡(luo)建設時(shi)就直(zhi)接(jie)使用光(guang)(guang)(guang)纖(xian)(xian)(xian)(xian)作為(wei)傳(chuan)輸介(jie)質(zhi)來(lai)建立骨干網(wang)(wang)(wang)，還有(you)很(hen)多(duo)企(qi)業(ye)(ye)基于商業(ye)(ye)的(de)(de)需要也紛紛升級原有(you)的(de)(de)網(wang)(wang)(wang)絡(luo)。但是(shi)出于資(zi)金(jin)、人(ren)力或(huo)時(shi)間(jian)的(de)(de)考慮，很(hen)多(duo)企(qi)業(ye)(ye)用戶都迫(po)切需要一(yi)種廉(lian)價的(de)(de)方案，既能將成(cheng)本降低，同時(shi)也讓原有(you)的(de)(de)設備得(de)到(dao)最大的(de)(de)保值。　所以(yi)很(hen)多(duo)的(de)(de)企(qi)業(ye)(ye)的(de)(de)做法就是(shi)主(zhu)(zhu)干網(wang)(wang)(wang)為(wei)光(guang)(guang)(guang)纖(xian)(xian)(xian)(xian)，而內部局域(yu)網(wang)(wang)(wang)的(de)(de)傳(chuan)輸介(jie)質(zhi)一(yi)般為(wei)銅線、雙絞線。但如(ru)何實(shi)現局域(yu)網(wang)(wang)(wang)同光(guang)(guang)(guang)纖(xian)(xian)(xian)(xian)主(zhu)(zhu)干網(wang)(wang)(wang)相連(lian)呢(ni)？這就需要在(zai)(zai)不(bu)同端(duan)口、不(bu)同線形、不(bu)同光(guang)(guang)(guang)纖(xian)(xian)(xian)(xian)間(jian)進(jin)行(xing)轉換(huan)(huan)并保證鏈接(jie)質(zhi)量。光(guang)(guang)(guang)纖(xian)(xian)(xian)(xian)收發器(qi)是(shi)一(yi)種將短距離(li)的(de)(de)雙絞線電信號(hao)和長距離(li)的(de)(de)光(guang)(guang)(guang)信號(hao)進(jin)行(xing)互換(huan)(huan)的(de)(de)以(yi)太網(wang)(wang)(wang)傳(chuan)輸媒體轉換(huan)(huan)單元，在(zai)(zai)很(hen)多(duo)地方也被(bei)稱之為(wei)光(guang)(guang)(guang)電轉換(huan)(huan)器(qi)或(huo)光(guang)(guang)(guang)纖(xian)(xian)(xian)(xian)轉換(huan)(huan)器(qi)（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，實現電源保護和自動切換。同(tong)時支持超寬(kuan)的(de)工作溫度范(fan)圍(wei)，支持0～120公里齊全的(de)傳(chuan)輸距離。

單模收(shou)(shou)發器覆蓋的(de)范圍可以從20公(gong)里至120公(gong)里。需要指(zhi)出的(de)是因傳輸距(ju)離的(de)不(bu)同(tong)，光(guang)(guang)纖(xian)收(shou)(shou)發器本身(shen)的(de)發射(she)功率(lv)、接(jie)收(shou)(shou)靈(ling)(ling)(ling)敏(min)度(du)(du)(du)和使(shi)用波長(chang)也會不(bu)一樣。如(ru)20公(gong)里光(guang)(guang)纖(xian)收(shou)(shou)發器的(de)發射(she)功率(lv)一般在-15～-7db之間，接(jie)收(shou)(shou)靈(ling)(ling)(ling)敏(min)度(du)(du)(du)為-30db，使(shi)用1310nm的(de)波長(chang)；而120公(gong)里光(guang)(guang)纖(xian)收(shou)(shou)發器的(de)發射(she)功率(lv)多在-5～0dB之間，接(jie)收(shou)(shou)靈(ling)(ling)(ling)敏(min)度(du)(du)(du)為-38dB，使(shi)用1550nm的(de)波長(chang)。
