2.雙工轉單工工業級光纖收發器

有you時shi，企qi業ye網wang絡luo的de傳chuan輸shu還hai需xu要yao將jiang雙shuang工gong光guang纖xian轉zhuan換huan為wei單dan工gong光guang纖xian，這zhe主zhu要yao取qu決jue於yu收shou發fa設she備bei裏li麵mian的de光guang纖xian數shu。顧gu名ming思si義yi，單dan纖xian光guang纖xian的de接jie收shou發fa送song的de數shu據ju是shi在zai一yi根gen光guang纖xian上shang傳chuan輸shu，雙shuang纖xian光guang纖xian的de接jie收shou發fa送song的de數shu據ju是shi在zai一yi對dui光guang纖xian上shang傳chuan輸shu。單dan纖xian設she備bei可ke以yi節jie省sheng一yi半ban的de光guang纖xian，即ji在zai一yi根gen光guang纖xian上shang實shi現xian數shu據ju的de接jie收shou和he發fa送song，在zai光guang纖xian資zi源yuan緊jin張zhang的de地di方fang十shi分fen適shi用yong。這zhe類lei產chan品pin采cai用yong了le波bo分fen複fu用yong的de技ji術shu

，使shi用yong的de波bo長chang多duo為wei1310nm和1550nm。下圖工業級光纖收發器的兩個端口一個是單纖，一個是雙纖，實現雙纖到單纖的轉換。

3.波段轉換收發器

WDM 光放大中繼器係列(OEO)的最大特點是能在不改變數據/信號內容的前提下，通過不同的波長對信號進行接收
、放大和重新發射。如今，波長的轉換隻能通過WDM 光放大中繼器係列(OEO)來實現。WDM光放大中繼器係列(OEO)像(xiang)再(zai)生(sheng)器(qi)一(yi)樣(yang)工(gong)作(zuo)
，將(jiang)光(guang)輸(shu)入(ru)信(xin)號(hao)轉(zhuan)換(huan)為(wei)電(dian)信(xin)號(hao)
，通(tong)過(guo)一(yi)個(ge)新(xin)的(de)電(dian)脈(mai)衝(chong)振(zhen)幅(fu)和(he)波(bo)形(xing)
，生(sheng)成(cheng)一(yi)個(ge)輸(shu)入(ru)信(xin)號(hao)的(de)邏(luo)輯(ji)副(fu)本(ben)，並(bing)利(li)用(yong)這(zhe)一(yi)電(dian)信(xin)號(hao)驅(qu)動(dong)發(fa)射(she)器(qi)產(chan)生(sheng)出(chu)一(yi)個(ge)具(ju)有(you)新(xin)的(de)波(bo)長(chang)的(de)光(guang)信(xin)號(hao)。
