Pali mitundu yambiri ya zingwe za zigamba ndi michira ya nkhumba.Ndizofunikira kudziwa kuti ma fiber pigtails ndi zingwe zapatch si lingaliro.Kusiyanitsa kwakukulu pakati pa zingwe za fiber optic patch ndi fiber optic pigtails ndikuti mapeto amodzi okha a fiber optic pigtail ali ndi cholumikizira chosunthika, ndipo zigawo zonse za chingwechi zimakhala ndi zolumikizira zosunthika.Mwachidule, chingwe cha chigamba chikhoza kugawidwa pawiri ndikugwiritsidwa ntchito ngati pigtail.
1.Kodi jumpers ndi pigtails ndi chiyani?
Jumpers ndi zingwe zolumikizidwa mwachindunji ndi makompyuta apakompyuta kapena zida kuti zithandizire kulumikizana ndi kasamalidwe ka chipangizocho.Zodumpha zimakhala ndi chitetezo chokulirapo ndipo nthawi zambiri zimagwiritsidwa ntchito pakati pa mabokosi omaliza ndi ma transceivers owoneka.
Mapeto amodzi okha a pigtail ali ndi cholumikizira, ndipo mapeto enawo ndi cholumikizira CHIKWANGWANI, chomwe chimalumikizidwa ndi minyewa ina yamagetsi ngati mawonekedwe a fusion splicing, omwe nthawi zambiri amawonekera mu bokosi la optical fiber terminal.
2. Mitundu ya optical fiber jumpers
Zodumphira zowoneka bwino zimagawidwa kukhala zodumphira zamtundu umodzi wamtundu umodzi ndi ma multi-mode fiber jumpers mu zida zotumizira ma data.Zojambulira zamtundu umodzi zimakhala zachikasu, zolumikizira ndi manja oteteza zimakhala zabuluu, kutalika kwa mafunde ndi 1310nm/1550nm, ndipo mtunda wotumizira ndi 10km/40km, mtunda wautali wotumiza; multimode fiber jumper: nthawi zambiri lalanje kapena nyanja yabuluu, cholumikizira ndi chivundikiro choteteza ndi. beige kapena wakuda, kutalika kwake ndi 850nm, mtunda wotumizira ndi 500m, ndipo mtunda wotumizira ndi waufupi.
Zingwe za CHIKWANGWANI zimatha kugawidwa m'mitundu iyi motengera mtundu wa cholumikizira:
①LC mtundu wa optical fiber jumper: cholumikizira masikweya, chopangidwa ndi makina osavuta kugwiritsa ntchito a jack (RJ) latch, ndi cholumikizira cholumikizira ma module a SFP optical, omwe amagwiritsidwa ntchito nthawi zambiri mu ma router.
②SC mtundu wa kuwala kwa fiber jumper: cholumikizira chamakona anayi, pogwiritsa ntchito pulagi-mu bawuti mtundu zomangira njira, ndiye cholumikizira kulumikiza GBIC kuwala module, ndipo nthawi zambiri ntchito rauta ndi masiwichi.
③ST mtundu wa kuwala kwa fiber jumper: cholumikizira mutu wozungulira, chomangirizidwa ndi phula, chomwe chimagwiritsidwa ntchito kwambiri pa chimango chogawa CHIKWANGWANI.
④ FC-mtundu wolumphira kuwala CHIKWANGWANI: zozungulira kuwala CHIKWANGWANI cholumikizira, kunja kwapangidwa ndi zitsulo, komanso amangirira ndi turnbuckles, makamaka ntchito mbali ODF.
⑤ MPO-mtundu wa optical fiber jumper: Amapangidwa ndi zolumikizira ziwiri za pulasitiki zolondola kwambiri komanso zingwe zowoneka bwino.Imatengera kapangidwe kakang'ono kakang'ono ndipo imakhala ndi kachulukidwe kakang'ono komanso kulumikizana kokhazikika komanso kodalirika.
⑥MTP mtundu wa fiber patch zingwe: zingwe za fiber patch zokhala ndi ma cores ambiri ndi kukula kochepa zimagwiritsidwa ntchito pamizere yophatikizika kwambiri.
3.Mtundu wa pigtail
Monga ma jumper a ulusi, ma pigtails amagawidwa kukhala ma pigtails amtundu umodzi ndi ma pigtails amitundu yambiri malinga ndi mitundu ya ulusi.Mchimake wakunja wa pigtails single-mode ndi wachikasu, ndi wavelength wa 1310nm/1550nm, ndi kufala mtunda wa 10km/40km.Kulumikizana kwakutali;m'chimake akunja pigtail multimode ndi lalanje / nyanja buluu, wavelength ndi 850nm, ndi kufala mtunda ndi 500m.Amagwiritsidwa ntchito polumikiza mtunda waufupi.Ma fiber jumpers ndi pigtails operekedwa ndi ETU-LINK ali ndi mitundu yosiyanasiyana yosankha.
Ma pigtails amatha kugawidwa m'magulu otsatirawa malinga ndi mtundu wa cholumikizira:
①LC-mtundu wa pigtail cholumikizira: Kukula kwa pini ndi manja a cholumikizira chamtundu wa LC-pigtail ndi theka la zolumikizira ziwiri pamwambapa, zomwe zimathandizira kugwiritsa ntchito danga kwa chimango chogawa.Imatengera jack modular yomwe ndi yosavuta kugwiritsa ntchito.(RJ) Mfundo ya latching imapangidwa.
②SC-mtundu wa pigtail cholumikizira: Zimapangidwa ndi zinthu zapulasitiki zauinjiniya, mtengo wake ndi wotsika mtengo, chipolopolocho chili ndi makona anayi, mapini omwe ali kumapeto kwa mating ndi PC kapena njira zamtundu wa APC, ndipo njira yokonzera ndi pulagi-mu latch. mtundu, umene ndi yabwino ntchito osati oxidize mosavuta.
③ ST-mtundu wa pigtail cholumikizira: Chosiyana ndi SC-mtundu wa pigtail cholumikizira, pachimake cholumikizira cha ST-mtundu wa pigtail chimawonekera pomwe pachimake cha SC-mtundu wa pigtail cholumikizira chili mkati mwa cholumikizira.Nthawi zambiri, ST imagwiritsidwa ntchito mu 10Mbps Ethernet system.Type pigtail cholumikizira, SC mtundu pigtail cholumikizira ntchito 10Mbps Efaneti.
④FC-mtundu wa pigtail cholumikizira: chomwe chimadziwikanso kuti cholumikizira chozungulira, chimapangidwa ndi chitsulo ndipo chimakhala cholimba.Nthawi zambiri amagwiritsidwa ntchito pazigamba.
4.Kugwiritsa ntchito jumpers ndi pigtails
Ma Jumpers amagwiritsidwa ntchito makamaka polumikizana pakati pa cholumikizira chamtundu wa kuwala kapena cholumikizira chidziwitso cha fiber ndi chosinthira, kulumikizana pakati pa chosinthira ndi chosinthira, kulumikizana pakati pa chosinthira ndi kompyuta yapakompyuta, komanso kulumikizana pakati pa soketi yazidziwitso za fiber. ndi kompyuta yapakompyuta.Kwa oyang'anira, zipinda zopangira zida ndi magawo ogwirira ntchito.
Ma pigtails amagwiritsidwa ntchito makamaka pamakina olankhulirana owoneka bwino, maukonde olumikizana nawo, kutumiza kwa data, optical CATV, ma network amderali (LAN), zida zoyesera, masensa owoneka bwino, maseva a seri, FTTH / FTTX, ma network olumikizirana ndi makhazikitsidwe asanathe.
5.Precautions kwa jumpers ndi pigtails
① Mafunde a transceiver a ma module a kuwala olumikizidwa ndi jumper ayenera kukhala ofanana.Kawirikawiri, ma modules optical optical modules amafanana ndi ma jumper amitundu yambiri, ndipo ma modules optical optical aatali amafanana ndi ma jumpers a single-mode kuti atsimikizire kulondola kwa kutumiza deta.
②Wodumphira ayenera kuchepetsa mafunde momwe angathere panthawi ya waya, kuti achepetse kutsika kwa chizindikiro cha kuwala panthawi yotumizira.
③Cholumikizira cholumphira chiyenera kukhala choyera.Pambuyo pa ntchito, cholumikizira chiyenera kusindikizidwa ndi chophimba chotetezera kuti mafuta ndi fumbi zisalowe.Ngati yadetsedwa, gwiritsani ntchito thonje swab yoviikidwa mu mowa kuti muyeretse.
④Pigtail ndi yowonda, ndipo gawo la mtanda la pigtail lili pakona ya madigiri 8.Sichigonjetsedwa ndi kutentha kwakukulu ndipo chidzawonongeka ngati chidutsa 100 ° C.Choncho, pewani kugwiritsa ntchito kumalo otentha kwambiri.
Optical fiber zolumikizira ndi gawo lofunikira pakulankhulana kwa fiber.Pankhani ya kufalitsa deta, ubwino wa ferrule, teknoloji yopanga ndi njira zonse zimatsimikizira kukhazikika kwa kufalitsa deta.
