4、傳輸中繼：當(dāng)實(shí)際傳輸距離超過收發(fā)器的標(biāo)稱傳輸距離，特別是實(shí)際傳輸距離超過120Km的時(shí)候，在現(xiàn)場(chǎng)條件允許的情況下，采用2臺(tái)收發(fā)器背對(duì)背進(jìn)行中繼或采用光-光轉(zhuǎn)換器進(jìn)行中繼，是一種很經(jīng)濟(jì)有效的解決方案。 5、單多模轉(zhuǎn)換：當(dāng)網(wǎng)絡(luò)間出現(xiàn)需要單多模光纖連接時(shí)，可以用1臺(tái)多模收發(fā)器和1臺(tái)單模收發(fā)器背對(duì)背連接，解決了單多模光纖轉(zhuǎn)換的問題。 6、波分復(fù)用傳輸：當(dāng)長(zhǎng)距離光纜資源不足，為了提高光纜的使用率，降低造價(jià)，可將收發(fā)器和波分復(fù)用器配合使用，讓兩路信息在同一對(duì)光纖上傳輸。無錫PCM光端機(jī)品牌但由于光源的非線性較嚴(yán)重，因此其信噪比、傳輸距離和傳輸頻率都十分有限。</p><div style="width:100%;text-align:
