監控工程中光纖熔(rong)接技巧

光纖是(shi)監控工(gong)程中(zhong)常見(jian)的一(yi)種傳輸(shu)(shu)方式。使用光纖傳輸(shu)(shu)少不了熔(rong)纖。熔(rong)纖是(shi)一(yi)項技術(shu)活,需(xu)要心(xin)細、手穩!熔(rong)纖的方法(fa)歸納起來有四步(bu),即剝(bo)、切、熔(rong)、護。每個步(bu)驟都有具體的操作步(bu)驟。今天我們就(jiu)來聊聊監控工(gong)程中(zhong)光纖熔(rong)接(jie)的技巧(qiao)!

監控工程 光纖熔接

光(guang)纖熔(rong)接分(fen)為剝、切、熔(rong)、護四大步驟,每個步驟都和最終(zhong)的光(guang)纖傳輸(shu)情(qing)況息息相關。

監(jian)控工程中(zhong)光纖熔接(jie)技巧之剝(bo)

所(suo)謂的(de)(de)剝是指:將光(guang)(guang)纜中的(de)(de)光(guang)(guang)纖芯(xin)剝離(li)出來,這其中包括了最外(wai)層的(de)(de)塑料層,中

間的(de)鋼絲,內層(ceng)中的(de)塑料(liao)層(ceng)及(ji)光纖(xian)(xian)(xian)(xian)(xian)表面的(de)顏色(se)油漆(qi)層(ceng)。剝纖(xian)(xian)(xian)(xian)(xian)講究“平(ping)、穩、快(kuai)(kuai)”三字要(yao)(yao)訣。即持纖(xian)(xian)(xian)(xian)(xian)要(yao)(yao)平(ping),用力要(yao)(yao)穩、剝纖(xian)(xian)(xian)(xian)(xian)要(yao)(yao)快(kuai)(kuai)!持纖(xian)(xian)(xian)(xian)(xian)要(yao)(yao)平(ping),保證(zheng)不(bu)會在剝纖(xian)(xian)(xian)(xian)(xian)的(de)過程中折斷光纖(xian)(xian)(xian)(xian)(xian);用力要(yao)(yao)穩,保證(zheng)剝開之(zhi)后不(bu)會損傷光纖(xian)(xian)(xian)(xian)(xian);剝纖(xian)(xian)(xian)(xian)(xian)要(yao)(yao)快(kuai)(kuai),保證(zheng)剝出來(lai)的(de)纖(xian)(xian)(xian)(xian)(xian)盡可能少接(jie)觸灰塵等(deng)!

監控工程中光纖熔接技巧之(zhi)切(qie)

所謂的(de)(de)切(qie)(qie)(qie)是指:將剝好準備熔接的(de)(de)光(guang)纖的(de)(de)端面用(yong)“切(qie)(qie)(qie)割(ge)(ge)機”切(qie)(qie)(qie)齊。切(qie)(qie)(qie)割(ge)(ge)是光(guang)纖端面制備中最為(wei)關鍵的(de)(de)部(bu)分,精密(mi)、優良的(de)(de)切(qie)(qie)(qie)刀(dao)(dao)是基礎,嚴格、科學的(de)(de)操(cao)(cao)作(zuo)規范是保證(zheng)。切(qie)(qie)(qie)割(ge)(ge)光(guang)纖的(de)(de)切(qie)(qie)(qie)刀(dao)(dao)有手(shou)動(dong)(dong)(dong)(dong)和(he)電(dian)動(dong)(dong)(dong)(dong)之分。手(shou)動(dong)(dong)(dong)(dong)切(qie)(qie)(qie)刀(dao)(dao)操(cao)(cao)作(zuo)簡單、性能可靠(kao),隨(sui)著操(cao)(cao)作(zuo)者(zhe)的(de)(de)技(ji)術水平提高,切(qie)(qie)(qie)割(ge)(ge)效率和(he)質(zhi)量以隨(sui)之而提高。但是,手(shou)動(dong)(dong)(dong)(dong)切(qie)(qie)(qie)刀(dao)(dao)對(dui)環境溫度要求較高。電(dian)動(dong)(dong)(dong)(dong)切(qie)(qie)(qie)刀(dao)(dao)切(qie)(qie)(qie)割(ge)(ge)質(zhi)量可靠(kao),尤其是在野外寒(han)冷的(de)(de)環境下,切(qie)(qie)(qie)割(ge)(ge)質(zhi)量不受室外氣溫的(de)(de)影(ying)響。但是電(dian)動(dong)(dong)(dong)(dong)切(qie)(qie)(qie)刀(dao)(dao)的(de)(de)操(cao)(cao)作(zuo)較為(wei)復雜且工作(zuo)速度恒定(ding)。熟練的(de)(de)操(cao)(cao)作(zuo)者(zhe)在常溫下進行快速光(guang)纜(lan)接續(xu)或搶(qiang)險,采用(yong)手(shou)動(dong)(dong)(dong)(dong)切(qie)(qie)(qie)刀(dao)(dao)為(wei)宜;反(fan)之,初學者(zhe)或在野外較寒(han)冷條件下作(zuo)業時(shi),直(zhi)用(yong)電(dian)動(dong)(dong)(dong)(dong)切(qie)(qie)(qie)刀(dao)(dao)。

監控工程 光纖熔接

監(jian)控工程中(zhong)光纖熔(rong)接技(ji)巧之(zhi)熔(rong)

所(suo)謂的(de)熔(rong)是(shi)指:將兩根光(guang)纖(xian)(xian)在“熔(rong)接機(ji)(ji)”中熔(rong)接到一(yi)起。首先在選(xuan)擇熔(rong)接機(ji)(ji)時(shi)(shi),應(ying)(ying)選(xuan)擇與光(guang)纜工程要求想匹配的(de)蓄電(dian)(dian)池(chi)容量和(he)精密度合適(shi)的(de)熔(rong)接設備(bei)。熔(rong)接程序熔(rong)接前(qian)根據光(guang)纖(xian)(xian)的(de)材料和(he)類(lei)型(xing),設置(zhi)好最佳預(yu)熔(rong)主熔(rong)電(dian)(dian)流和(he)時(shi)(shi)間(jian)及(ji)光(guang)纖(xian)(xian)送入量等(deng)關鍵參數。熔(rong)接過程中還應(ying)(ying)及(ji)時(shi)(shi)清潔熔(rong)接機(ji)(ji)“V”形槽、電(dian)(dian)極(ji)、物(wu)鏡、熔(rong)接室(shi)等(deng),隨時(shi)(shi)觀察熔(rong)接中有無氣泡、過細(xi)、過粗、虛熔(rong)、分(fen)(fen)離等(deng)不良(liang)現象(xiang),注意OTDR跟蹤監測結果(guo),及(ji)時(shi)(shi)分(fen)(fen)析產生上述(shu)不良(liang)現象(xiang)的(de)原因,采取相應(ying)(ying)的(de)改進措施。如多次出現虛熔(rong)現象(xiang),應(ying)(ying)檢查(cha)熔(rong)接的(de)兩根光(guang)纖(xian)(xian)的(de)材料、型(xing)號(hao)是(shi)否(fou)匹配,切刀和(he)熔(rong)接機(ji)(ji)是(shi)否(fou)被灰塵(chen)污染,并檢查(cha)電(dian)(dian)極(ji)氧化狀(zhuang)況,若均(jun)無問題(ti),則應(ying)(ying)適(shi)當提高熔(rong)接電(dian)(dian)流。

監控工程中光纖(xian)熔接技巧之護

所謂的(de)(de)護是(shi)指:將已(yi)經熔(rong)接(jie)好的(de)(de)光纖接(jie)頭部(bu)份用“熱縮管”保護起來(lai)。熱縮套管應在剝覆前(qian)穿入,嚴禁(jin)在端(duan)(duan)面(mian)制備(bei)后(hou)穿入。裸(luo)纖的(de)(de)清(qing)(qing)潔、切(qie)割和熔(rong)接(jie)的(de)(de)時間應緊(jin)密(mi)銜接(jie),不可間隔過長,特別是(shi)已(yi)制備(bei)的(de)(de)端(duan)(duan)面(mian)切(qie)勿(wu)放(fang)在空(kong)氣中。移動時要輕拿(na)輕放(fang),防止(zhi)與其它物件(jian)擦碰。在接(jie)續中,應根據環境,對切(qie)刀“V”形槽(cao)、壓板(ban)、刀刃(ren)進行清(qing)(qing)潔,謹防端(duan)(duan)面(mian)污染(ran)。
