        什么是單模單纖光纖收發(fā)器?

        單模單纖光纖收發(fā)器,單纖設(shè)備可以節(jié)省一半的光纖,即在一根光纖上實現(xiàn)數(shù)據(jù)的接收和發(fā)送。

        單纖光纖收發(fā)器:接收發(fā)送的數(shù)據(jù)在一根光纖上傳輸。顧名思義,單纖設(shè)備可以節(jié)省一半的光纖,即在一根光纖上實現(xiàn)數(shù)據(jù)的接收和發(fā)送,在光纖資源緊張的地方十分適用。這類產(chǎn)品采用了波分復(fù)用的技術(shù),使用的波長多為1310nm和1550nm。但由于單纖收發(fā)器產(chǎn)品沒有統(tǒng)一國際標準,因此不同廠商產(chǎn)品在互聯(lián)互通時可能會存在不兼容的情況,另外由于使用了波分復(fù)用,單纖收發(fā)器產(chǎn)品普遍存在信號衰耗大的特點。目前市面上的光纖收發(fā)器多為雙纖產(chǎn)品,此類產(chǎn)品較為成熟和穩(wěn)定,但需要更多的光纖。

        什么是單模雙纖光纖收發(fā)器?

        單模雙纖光纖收發(fā)器,單纖雙向光纖收發(fā)器類型是光電轉(zhuǎn)換設(shè)備,優(yōu)點是節(jié)省一半光纖。

        單纖雙向光纖收發(fā)器是采用波分復(fù)用技術(shù),在一根光纖上實現(xiàn)數(shù)據(jù)的發(fā)送和接收,將網(wǎng)絡(luò)電信號和光信號互相轉(zhuǎn)換的光電轉(zhuǎn)換設(shè)備。單纖雙向光纖收發(fā)器近年來較流行。優(yōu)點是它可以節(jié)省一半光纖,缺節(jié)省一半光纖是目前沒有統(tǒng)一的國際標準,各廠商生產(chǎn)的產(chǎn)品兼容性一般,并且穩(wěn)定性比雙纖產(chǎn)品稍差。目前,市場上光纖收發(fā)器還是以雙纖產(chǎn)品為主。

        單模單纖和單模雙纖光纖收發(fā)器有何區(qū)別?

        單模多模是取決于光纜,單纖雙纖是指一芯光纖傳輸或者是兩芯光纖傳輸;單模是指采用的是單模光纜,單纖收發(fā)器是只用一根芯,兩端都接這根芯,兩端的收發(fā)器采用不同的光波長,所以能在一根芯里傳輸光信號。雙纖收發(fā)器就是采用了兩根芯,一根發(fā)送一根接收,一端是發(fā)的另一端就必須插在收的口,就是兩端要交叉。

        單模雙模在具體應(yīng)用上,多模的用量要高于單模,,主要在500m以下的布線范圍內(nèi),多模已經(jīng)能滿足,雖然性能不如單模。單模在500m以上或者對帶寬要求較高的環(huán)境下應(yīng)用,大多是企業(yè)級等大規(guī)模場地應(yīng)用。因為光纖模塊的工作穩(wěn)定性和性能大大優(yōu)于收發(fā)器,所以在單模這種對性能要求較高的應(yīng)用環(huán)境內(nèi),很少企業(yè)會用收發(fā)器,而是直接用模塊來代替,自然生產(chǎn)單模收發(fā)器的廠商就少了, 價格就高了。

而單纖、雙纖一般都具有兩個口,而且雙纖的兩個口距離較近,分別標明TX,RX,一個發(fā)送,一個接收,是指定的;單纖的兩個口一般用P1,P2標明,兩個口都能分別進行收發(fā),也就是用一個口就完成收發(fā),所以叫單纖。光收發(fā)器TX、RX是代表收和發(fā)。光收發(fā)器有兩種:一種是單模、一種是雙模,就像公路如果只有單行線可能會塞車,如果是雙行線就順暢的多了,所以很明顯雙模收收發(fā)器穩(wěn)定性好點。

單纖就是兩臺收發(fā)器間只用一根光纖連接就可以了,雙纖的較為普遍,需要使用兩根光纖,價格上單纖的略高。多模收發(fā)器接收多個傳輸模式,傳輸距離比較近,單模收發(fā)器只接收單一的模式;傳輸距離比較遠。雖然多模都在淘汰中,但是因為價格較低很多在監(jiān)控啊近距離傳輸方面還有很多在用。多模收發(fā)器和多模光纖對應(yīng),單模和單模對應(yīng), 不能混用。

以上內(nèi)容為單纖和雙纖的區(qū)別,有興趣的小伙伴,可以深入解一下。
