Kunezinhlobo eziningi zezintambo ze-patch kanye ne-pigtails. Kuyaphawuleka ukuthi i-fiber pigtails kanye nezintambo ze-patch aziwona umqondo. Umehluko omkhulu phakathi kwezintambo ze-fiber optic patch kanye ne-fiber optic pigtails ukuthi ukuphela kwendawo eyodwa kuphela ye-fiber optic pigtail enesixhumanisi esisuswayo, futhi zombili izingxenye zentambo yesichibi zinezixhumi ezihambayo. Ngamagama alula, intambo yesichibi ingahlukaniswa kabili futhi isetshenziswe njenge-pigtail.
1.Ayini ama-jumpers kanye nemisila yengulube?
Ama-Jumpers amakhebuli axhunywe ngokuqondile kumakhompuyutha edeskithophu noma amadivayisi ukusiza ukuxhumana nokuphathwa kwedivayisi. Ama-Jumpers anongqimba oluyisivikelo olujiyile futhi avame ukusetshenziswa phakathi kwamabhokisi etheminali nama-transceiver abonakalayo.
Ingxenye eyodwa kuphela ye-pigtail inesixhumi, kanti enye iyisixhumi se-fiber optical, esixhunywe kwamanye ama-fiber optical cores ngendlela yokuhlanganisa i-fusion, evame ukuvela ebhokisini le-fiber optical.
2.Izinhlobo ze-optical fiber jumpers
Ama-Optical fibre jumper ahlukaniswe abe ama-fibre jumper emodi eyodwa kanye nama-multi-mode fibre jumpers kumishini yokudlulisa idatha. Ama-jumper e-fiber emodi eyodwa ngokuvamile aphuzi, izixhumi nemikhono evikelayo iluhlaza okwesibhakabhaka, ubude begagasi buyi-1310nm/1550nm, futhi ibanga lokudlulisela liyi-10km/40km, ibanga elide lokudlulisela; i-multimode fiber jumper: ngokuvamile i-orange noma eluhlaza okwesibhakabhaka, isixhumi nekhava yokuzivikela. i-beige noma emnyama, ubude be-waveleng ngu-850nm, ibanga lokudlulisela lingama-500m, futhi ibanga lokudlulisela lifushane.
Izintambo ze-fiber patch ngokuvamile zingahlukaniswa zibe izinhlobo ezilandelayo ngokuya ngohlobo lwesixhumi:
①LC uhlobo lwe-optical fibre jumper: isixhumi esiyisikwele, esenziwe ngendlela elula yokusebenzisa i-modular jack (RJ) latch mechanism, iyisixhumi sokuxhuma amamojula e-SFP optical, avame ukusetshenziswaimizila.
②SC uhlobo lwe-optical fibre jumper: isixhumi esingunxande, sisebenzisa indlela yokuqiniswa yohlobo lwe-plug-in bolt, iyisixhumi sokuxhuma i-GBIC optical module, futhi ivamise ukusetshenziswaimizilafuthiamaswishi.
③ST uhlobo lwe-optical fibre jumper: isixhumi sekhanda eliyindilinga, siboshwe ngebhande lesikulufu, esivame ukusetshenziswa kuhlaka lokusabalalisa i-fiber optical.
④I-FC-uhlobo lwe-fiber optical jumper: isixhumi esiyindilinga se-fiber optical, ingaphandle lenziwe ngezinto zensimbi, futhi siphinde siboshwe ngama-turnbuckles, ngokuvamile asetshenziswa ohlangothini lwe-ODF.
⑤ I-MPO-type optical fibre jumper: Yakhiwe ngezixhumi ezimbili ezibunjiwe zepulasitiki ezinembayo kanye nezintambo ezibonakalayo. Yamukela umklamo omncane futhi inokuminyana okukhulu nokuxhumana okuzinzile nokuthembekile.
⑥Izintambo zohlobo lwe-MTP ze-fiber optical patch: izintambo ze-fiber patch ezinenombolo enkulu yama-cores nosayizi omncane zisetshenziswa ezindaweni zomugqa we-fiber optical ohlanganisiwe wokuminyana okuphezulu.
3.Uhlobo lwe-pigtail
Njengama-fiber jumpers, ama-pigtails ahlukaniswe abe yi-pigtails yemodi eyodwa kanye ne-multi-mode pigtails ngokuya ngezinhlobo ze-fiber. Igobolondo langaphandle le-pigtails yemodi eyodwa liphuzi, linobude obungu-1310nm/1550nm, kanye nebanga lokudlulisela elifika ku-10km/40km. Ukuxhumana okude; umgodla wangaphandle we-pigtail yemodi ehlukahlukene unombala osawolintshi/ichibi oluhlaza okwesibhakabhaka, ubude begagasi bungama-850nm, kanti ibanga lokudlulisela lingama-500m. Isetshenziselwa ukuxhumana kwebanga elifushane. I-fiber jumpers kanye ne-pigtails ehlinzekwa yi-ETU-LINK inezinhlobo ezihlukahlukene ongakhetha kuzo.
Ama-pigtails ngokuvamile angahlukaniswa abe yizinhlobo ezilandelayo ngokuya ngohlobo lwesixhumi:
①LC Isixhumi sohlobo lwe-pigtail: Usayizi wephinikhodi nomkhono wesixhumi se-pigtail sohlobo lwe-LC uwuhhafu wezixhumi ezimbili ezingenhla, okuthuthukisa ukusetshenziswa kwesikhala kohlaka lokusabalalisa olubonakalayo. Yamukela i-modular jack okulula ukuyisebenzisa. (RJ) Umgomo wokuxhuma wenziwa.
Isixhumi se-②SC sohlobo lwe-pigtail: Senziwe ngezinto zepulasitiki zobunjiniyela, intengo ishibhile, igobolondo liwunxande, izikhonkwane ezisesiphelweni sokukhwelana ngokuvamile ziyizindlela zokugaya ze-PC noma ze-APC, futhi indlela yokulungisa i-plug-in latch. uhlobo, olulungele ukusebenza futhi akulula ukulufaka i-oxidize.
③Isixhumi se-pigtail sohlobo lwe-ST: Ihlukile kusixhumi sohlobo lwe-pigtail yohlobo lwe-SC, umgogodla wesixhumi sohlobo lwe-ST sohlobo lwe-pigtail uyavezwa kuyilapho umgogodla wesixhumi se-pigtail sohlobo lwe-SC ungaphakathi kwesixhumi. Ngokuvamile, i-ST isetshenziswa ohlelweni lwe-Ethernet lwe-10Mbps. Thayipha isixhumi se-pigtail, isixhumi se-SC sohlobo lwe-pigtail sisetshenziswa ku-10Mbps Ethernet.
④Isixhumi se-pigtail sohlobo lweFC: esaziwa nangokuthi isixhumi esiyindilinga esiyintambo, senziwe ngensimbi futhi sinokuqina okuhle. Ivame ukusetshenziswa kuma-patch panel.
4.Ukusetshenziswa kwama-jumpers nama-pigtails
Ama-Jumpers asetshenziselwa ikakhulukazi ukuxhumana phakathi kohlaka lokusabalalisa i-fiber optical noma isokhethi yolwazi lwefiber optical kanyeshintsha, ukuxhumana phakathi kweshintshakanye neshintsha, ukuxhumana phakathi kweshintshakanye nekhompuyutha yedeskithophu, kanye nokuxhumana phakathi kwesokhethi yolwazi lwefiber optical kanye nekhompyutha yedeskithophu. Okokuphatha, igumbi lemishini kanye nezinhlelo ezingaphansi kwendawo yokusebenza.
Ama-pigtails asetshenziswa kakhulu ezinhlelweni zokuxhumana ze-optical, amanethiwekhi okufinyelela optical, ukudluliswa kwedatha ye-optical, i-CATV ye-optical, amanethiwekhi wendawo wendawo (LAN), imishini yokuhlola, izinzwa ezibonakalayo, amaseva we-serial, i-FTTH/FTTX, amanethiwekhi ezokuxhumana kanye nokufakwa kwangaphambilini.
5.Izinyathelo zokuqapha ama-jumpers kanye ne-pigtails
① Ubude beza beza be-transceiver bamamojula abonakalayo axhunywe i-jumper kufanele bufane. Ngokuvamile, amamojula we-short-wave optical afaniswa nama-jumpers wemodi eminingi, futhi amamojula optical amagagasi amade afaniswa nama-jumpers wemodi eyodwa ukuze kuqinisekiswe ukunemba kokudluliswa kwedatha.
②I-jumper kufanele inciphise ukusonga ngangokunokwenzeka phakathi nenqubo yokufaka izintambo, ukuze kuncishiswe ukuncishiswa kwesignali ye-optical ngesikhathi senqubo yokudlulisela.
③Isixhumi se-jumper kufanele sigcinwe sihlanzekile. Ngemuva kokusetshenziswa, isixhumi kufanele sivalwe ngesembozo sokuvikela ukuvimbela ukungena kwamafutha nothuli. Uma inamabala, sebenzisa i-swab kakotini ecwiliswe otshwaleni ukuze uyihlanze.
④I-pigtail izacile ngokuqhathaniswa, futhi ingxenye ephambanayo ye-pigtail iku-engeli engu-8 degrees. Ayimelani nezinga lokushisa eliphezulu futhi izolimala uma idlula ku-100°C. Ngakho-ke, gwema ukuyisebenzisa ezindaweni ezishisa kakhulu.
Izixhumi ze-fiber optical ziyingxenye ebalulekile yokuxhumana kwe-fiber optical. Mayelana nokudluliswa kwedatha, ikhwalithi ye-ferrule, ubuchwepheshe bokukhiqiza kanye nezindlela konke kunquma ukuzinza kokudluliswa kwedatha.
