Ulusi wa mchira (womwe umatchedwanso tail fiber, pigtail line).Ili ndi adaputala kumapeto kwina ndi kumapeto kwa chingwe cha fiber optic kumapeto kwina, komwe kumalumikizidwa ndi zida zina za fiber optic ndi kuwotcherera.Mwa kuyankhula kwina, jumper imadulidwa mu magawo awiri kuchokera pakati kuti ikhale michira iwiri ya nkhumba.Nthawi zambiri amawonekera m'mabokosi amtundu wa fiber optic terminal ndipo amagwiritsidwa ntchito kulumikiza zingwe za fiber optic ku ma transceivers a fiber optic (macouples, jumpers, etc. amagwiritsidwanso ntchito pakati pawo).
Gulu la pigtail
Monga ma jumper a fiber optic, ma pigtails amagawidwa kukhala ma pigtails amtundu umodzi ndi ma pigtails amitundu yambiri.Amasiyana mosiyanasiyana mumitundu, kutalika kwa mafunde, ndi nthawi yopatsirana.Nthawi zambiri, multimode pigtail ndi lalanje, kutalika kwake ndi 850nm, ndipo nthawi yotumizira ndi pafupifupi 500m.Single mode pigtail ndi yachikasu, ndipo kutalika kwa ntchito ndi 1310m kapena 1550m.Imatha kufalitsa nthawi yayitali, pafupifupi 10-40km..Kuonjezera apo, malingana ndi chiwerengero cha fiber cores, pigtails ikhoza kugawidwa kukhala imodzi-core pigtails, 4-core pigtails, 6-core pigtails, 8-core pigtails, 12-core pigtails, 24-core pigtails, etc. ku zosowa zosiyanasiyana.
Kugwiritsa ntchito pigtail
Chimodzi mwazofunikira kwambiri za pigtails ndi kulumikizana.The kuwala CHIKWANGWANI ndi pigtail zikugwirizana, ndi anabala CHIKWANGWANI ndi CHIKWANGWANI pigtail mu kuwala chingwe anasakaniza pamodzi mu lonse, ndi pigtail ali palokha CHIKWANGWANI mutu, amene chikugwirizana ndi kuwala CHIKWANGWANI transceiver kulumikiza CHIKWANGWANI kuwala ndi. awiri opotoka.Kumalo opangira zidziwitso.Pogwiritsa ntchito kuwala kwa fiber splicing, zinthu zoyamba zotsatirazi zimagwiritsidwa ntchito: mabokosi otsiriza a kuwala, ma transceivers a fiber optic, pigtails, couplers, mawaya apadera, odulira ulusi, ndi zina zotero. FC / PC, LC / PC, E2000 / APC, ndi ST / PC.
Pali mitundu isanu ya pigtails yomwe imagwiritsidwa ntchito kwambiri pamakina opatsirana:
Mtundu wa FC-SC, womwe umadziwikanso kuti pigtail yozungulira.FC imagwirizanitsa ndi bokosi la ODF, ndipo SC imagwirizanitsa ndi doko la kuwala kwa chipangizocho.Cholumikizira cha fiber optic ichi chimagwiritsidwa ntchito kwambiri mu zida zakale za SBS ndi Optix.
Mtundu wa FC-FC, womwe umadziwika kuti round pigtail.Nthawi zambiri amagwiritsidwa ntchito ngati chingwe chodumphira pakati pa ODF.
Mtundu wa SC-SC, womwe umadziwika kuti square-to-square pigtail, umagwiritsidwa ntchito polumikiza matabwa a kuwala pakati pa zida.
Mtundu wa SC-LC, mawonekedwe a LC amadziwika kuti pigtail yaing'ono ya square head pigtail, yomwe imatchedwa cholumikizira cholumikizira.Tsopano zida za OSN za Huawei, zida za ZTE's S, kuphatikiza zida za WDM za Lucent, zonse zimagwiritsa ntchito cholumikizira chamtundu wotere.
Mtundu wa LC-LC umagwiritsidwa ntchito polumikizira mkati mwa fiber pakati pa zida za WDM.Izi ndizosowa.
Pambuyo pazimenezi, ndikukhulupirira kuti tili ndi chidziwitso chozama cha nkhumba.Easy Sky Optical imapereka ma pigtails owoneka bwino okhala ndi mitundu yosiyanasiyana yolumikizira.Mtundu wa pigtail, kutalika, ndi kuchuluka kwa ma cores zitha kusinthidwa makonda.Zogulitsa zonse zimagwirizana ndi miyezo ya IEC, TIA / EIA, NTT ndi JIS, kutayika kwapang'onopang'ono kuyika ndi kutayika kwa chiwonetsero, kusinthasintha kwakukulu komanso kukhazikika, komanso kukhazikika kwakukulu.
