光隔離器是允許光向一個方向通過而阻止向相反方向通過的無源器件，作用是對光的方向進(jìn)行限制，使光只能單方向傳輸，通過光纖回波反射的光能夠被光隔離器很好的隔離，提高光波傳輸效率。光隔離器主要利用磁光晶體的法拉第效應(yīng)。光隔離器的特性是：正向插入損耗低，反向隔離度高，回波損耗高。 </p> <p>

在傳輸速度為千兆比特每秒的越洋海底光纜中，需要用到超過50個帶隔離器的光纖放大器，光隔離器對放大器的性能及應(yīng)用有極大的影響。隔離器的性能指標(biāo)將直接影響放大器的增益和噪聲，設(shè)計時常要求隔離器回波損耗，隔離度分別在50db和40db以上。 </p> <p> 在收看電視時，無線電波的多路徑造成了電視圖像的重影，信號過弱使畫面出現(xiàn)大片“雪花”，同時由于電磁波干擾造成了畫面質(zhì)量的下降;另一方面，衛(wèi)星電視要求配備相應(yīng)的衛(wèi)星電視接收機和FM/AM轉(zhuǎn)換器。所以，CATV受到了廣大用戶的歡迎，發(fā)展相當(dāng)迅速。目前發(fā)達(dá)國家的CATV網(wǎng)已占整個電視用戶的50%以上。在光纖CATV網(wǎng)中傳播多路徑信號的時候，必須使用高線性、小畸變、大輸出功率和低噪聲的DFB激光器，光器件上還必須裝上光隔離器，以保證反射信號得到足夠的衰減。由于模擬信號抗干擾能力較數(shù)字信號差，所以對隔離器的隔離度要求更高，常采用雙級光隔離器。那么隔離器的優(yōu)勢都有哪些呢？上?？臻g光隔離器定制價格</p><p

半導(dǎo)體激光器及光放大器等對來自連接器、熔接點、濾波器等的反射光非常敏感，并導(dǎo)致性能惡化。因此需要用光隔離器阻止反射光。光隔離器是一種只允許光沿一個方向通過而在相反方向阻擋光通過的光無源器件。它通過光纖回波反射的光能夠被光隔離器很好的隔離，隔離度了光隔離器對回波隔離（阻擋）能力。 </p> <p> <span style="font-size:12px;">光隔離器是一種非常有用的無源器件，通常被使用在光路中用來避免光路中的回波對光源，泵浦源以及其他發(fā)光器件造成的干擾和損害。包括偏振無關(guān)型在線式光隔離器和偏振相關(guān)小型化光隔離器?？梢宰鳛楣饫w放大器的組成部件使用或者用在精密光學(xué)測量系統(tǒng)中。所以我們經(jīng)?？梢栽诠饫w放大器、光纖環(huán)型激光器、有線電視的光纖線路、高速光纖傳輸系統(tǒng)等環(huán)境中看到它。</span>
