Imibuzo evame ukubuzwa ezintanjeni ze-fiber optic:
1, Ibiza malini ikhebula le-fiber drop?
Ngokuvamile, intengo ngekhebula le-fiber optic ngayinye isuka ku-$30 iye ku-$1000, kuye ngohlobo nenani lemicu: G657A1/G657A2/G652D/OM2/OM3/OM4/OM5, impahla yejakhethi PVC/LSZH/PE, ubude, kanye nomklamo wesakhiwo. nezinye izici zithinta intengo yamakhebuli okwehla.
2. Intandoizintambo ze-fiber optickulimale?
Izintambo ze-fiber optic zivame ukuhlukaniswa njengezintekenteke, njengengilazi.Yiqiniso, i-fiber iyingilazi.Imicu yengilazi esezintanjeni ze-fiber optic intekenteke, kanti nakuba izintambo ze-fiber optic ziklanyelwe ukuvikela imicu, zisengozini yokulimala kunezintambo zethusi.Umonakalo ovame kakhulu ukuphuka kwefiber, okunzima ukukubona.Kodwa-ke, ama-fibers angaphinda aphule ngenxa yokungezwani okukhulu ngesikhathi sokudonsa noma ukuphuka.Ingabe izintambo ze-fiber optic zizolimala Izintambo ze-fiber optic zivame ukonakala ngendlela eyodwa yezindlela ezimbili:
• Izintambo ze-fiber optic ezakhiwe ngaphambilini zingalimaza izixhumi uma kusetshenziswa ukushuba okukhulu ngesikhathi sokufakwa.Lokhu kungenzeka lapho izintambo ezinde ze-fiber optic zidlula emiseleni eqinile noma emathanjeni noma lapho izintambo ze-fiber optic zibambeka.
• Ikhebula le-fiber optic lasikwa noma laphuka phakathi nokusebenza futhi lalidinga ukuhlukaniswa kabusha ukuze lixhumeke kabusha.
3. Ngazi kanjani ukuthi ikhebula lami le-fiber lilimele?
Uma ubona izibani eziningi ezibomvu, isixhumi sibi futhi kufanele sishintshwe.Isixhumi sihle uma ubheka ngakolunye uhlangothi futhi ubone ukukhanya okuvela ku-fiber kuphela.Akulungile uma i-ferrule yonke ikhanya.I-OTDR ingakwazi ukunquma ukuthi isixhumi sonakalisiwe uma ikhebuli iyinde ngokwanele.
4, Ungawakhetha Kanjani Amakhebula E-Fiber Optic asuselwa ku-Bend Radius?
Irediyasi yokugoba yentambo ye-fiber optic ibalulekile ekufakweni.Izinto ezithinta irediyasi encane yekhebula le-fiber optic zifaka ukujiya kwejakhethi yangaphandle, ukudumba kwezinto ezibonakalayo, kanye nobubanzi obumaphakathi.
Ukuze kuvikelwe ubuqotho nokusebenza kwekhebuli, asikwazi ukuyigobela ngale kwerediyasi yayo evumelekile.Ngokuvamile, uma irediyasi yokugoba iyinkinga, i-fiber engezwani nokugoba iyanconywa, okuvumela ukuphathwa kwekhebula okulula nokunciphisa ukulahleka kwesignali nokulimala kwekhebula lapho intambo igobile noma isontekile.Ngezansi ishadi lerediyasi yokugoba.
Uhlobo Lwekhebula Le-Fiber
Ubuncane be-Bend Radius
I-G652D
30mm
I-G657A1
10mm
I-G657A2
7.5mm
B3
5.0mm
5, Indlela yokuhlola ikhebula le-fiber optic?
Thumela isignali yokukhanya kukhebuli.Lapho wenza lokhu, bheka ngokucophelela ngakolunye uhlangothi lwekhebula.Uma ukukhanya kutholwa kumongo, kusho ukuthi i-fiber ayiphukile, futhi ikhebula lakho lilungele ukusetshenziswa.
6, Kukangaki izintambo zefiber zidinga ukushintshwa?
Cishe iminyaka engu-30, ezintanjeni zefayibha ezifakwe kahle, amathuba okuhluleka esikhathini esinjalo angaba ngu-1 kweziyi-100,000.
Ngokuqhathanisa, ithuba lokungenelela komuntu (njengokumba) ukulimaza i-fiber cishe ku-1 ku-1,000 ngesikhathi esifanayo.Ngakho-ke, ngaphansi kwezimo ezamukelekayo, i-fiber yekhwalithi ephezulu enobuchwepheshe obuhle nokufakwa ngokucophelela kufanele kube okuthembekile kakhulu - inqobo nje uma ingaphazanyiswa.
7, Ingabe isimo sezulu esibandayo sizothinta izintambo ze-fiber optic?
Lapho izinga lokushisa lehla ngaphansi kukaziro futhi amanzi eba yiqhwa, iqhwa lakheka lizungeze imicu - okubangela ukuba imicu igogeke futhi igobe.Lokhu bese kunciphisa isignali ngefayibha, okungenani kunciphisa umkhawulokudonsa kodwa cishe kumise ukudluliswa kwedatha ngokuphelele.
8, Iyiphi kulezi zinkinga ezilandelayo ezodala ukulahleka kwesiginali?
Izimbangela ezivame kakhulu zokwehluleka kwe-fiber:
• Ukuphuka kwefiber ngenxa yokucindezeleka ngokomzimba noma ukugoba ngokweqile
• Amandla okudlulisa anganele
• Ukulahleka kwesignali okweqile ngenxa yezikhonkwane zekhebula ezinde
• Izixhumi ezingcolile zingabangela ukulahlekelwa kwesignali ngokweqile
• Ukulahleka kwesignali ngokweqile ngenxa yokungaphumeleli kwesixhumi noma isixhumi
• Ukulahleka kwesignali ngokweqile ngenxa yezixhumi noma izixhumi eziningi kakhulu
• Ukuxhumeka okungalungile kwefayibha kuphaneli yokunamathisela noma ithreyi le-splice
Ngokuvamile, uma uxhumano kwehluleka ngokuphelele, kungenxa yokuthi ikhebula liphukile.Kodwa-ke, uma ukuxhumana kuphazamiseka, kunezizathu ezimbalwa ezingenzeka:
• Ukunciphisa ikhebula kungase kube phezulu kakhulu ngenxa yezixhumi zekhwalithi engeyinhle noma izixhumi eziningi kakhulu.
• Uthuli, izigxivizo zeminwe, imihuzuko, nomswakama kungangcolisa izixhumi.
• Amandla okudlulisela aphansi.
• Ukuxhumana okungalungile ekhabetheni lezintambo.
9, Ijule kangakanani ikhebula?
Ukujula Kwekhebula: Ukujula okungabekwa kukho izintambo ezigqitshiwe kuzohluka kuye ngezimo zasendaweni, njengokuthi "imigqa eqandisiwe" (ukujula lapho umhlabathi uba yiqhwa unyaka nonyaka).Kuyatuswa ukungcwaba izintambo ze-fiber optic ekujuleni/ukumboza okungenani ama-intshi angu-30 (77 cm).
10, Ungawathola kanjani amakhebuli optical angcwatshwe?
Indlela engcono kakhulu yokuthola intambo ye-fiber optic iwukufaka isigxobo sekhebula epayipini, bese usebenzisa idivayisi yokukhomba ye-EMI ukuze uxhume ngokuqondile esigxotsheni sekhebula futhi ulandelele isignali, okuthi, uma yenziwe kahle, inganikeza indawo enembe kakhulu.
11, Ingabe izinsimbi zensimbi zingathola izintambo ezibonakalayo?
Njengoba sonke sazi, izindleko zokulimaza izintambo ezibukhoma ze-fiber optic ziphezulu.Ngokuvamile bathwala umthwalo omkhulu wezokuxhumana.Kubalulekile ukuthola indawo yabo eqondile.
Ngeshwa, banenselele yokuthola ngokuskena phansi.Aziyona insimbi futhi azikwazi ukusebenzisa insimbi ngesithwebuli sekhebula.Izindaba ezinhle ukuthi zivame ukugoqwa ndawonye futhi zingase zibe nezendlalelo zangaphandle.Kwesinye isikhathi, kulula ukuzibona kusetshenziswa izikena ze-radar ezingena phansi, izikhombi zamakhebula, noma izithungatha zensimbi.
12, Uyini umsebenzi weshubhu lesigcinalwazi kukhebula le-optical?
Amashubhu esibhafa asetshenziswa kuzintambo ze-fiber optic ukuvikela imicu ekuphazamisekeni kwesignali nezici zemvelo, njengoba evame ukusetshenziswa ezinhlelweni zangaphandle.Amashubhu ebhafa aphinde avimbe amanzi, okubaluleke kakhulu ezinhlelweni ze-5G ngoba asetshenziswa ngaphandle futhi avame ukuchayeka emvuleni naseqhweni.Uma amanzi engena ekhebulani bese eba yiqhwa, anganwebeka ngaphakathi kwekhebuli futhi alimaze ifayibha.
13. Ahlanganiswa kanjani izintambo ze-fiber optic?
Izinhlobo Zokuhlukanisa
Kunezindlela ezimbili zokuhlanganisa, i-mechanical noma i-fusion.Zombili izindlela zinikeza ukulahleka kokufakwa okuphansi kakhulu kunezixhumi ze-fiber optic.
I-Mechanical splicing
I-Optical cable mechanical splicing ingenye indlela engadingi i-fusion splicer.
Izinhlayiya zemishini ziyizinhlayiya zemicu emibili noma ngaphezulu ye-optical eqondanisa futhi ibeke izingxenye ezigcina imicu iqondaniswe ngokusebenzisa uketshezi oluhambisana nenkomba.
I-Mechanical splicing isebenzisa ukuhlanganisa okuncane komshini okungaba ngu-6 cm ubude kanye no-1 cm ububanzi ukuze kuxhunywe unomphela imicu emibili.Lokhu kuqondanisa ngokunembile imicu emibili engenalutho bese kuyivikela ngomshini.
Amakhava e-snap-on, amakhava anamathelayo, noma kokubili kusetshenziselwa ukuvikela uhlaka unomphela.
Imicu ayixhumene unomphela kodwa ihlanganiswa ukuze ukukhanya kudlule komunye kuya komunye.(ukulahlekelwa kokufakwa <0.5dB)
Ukulahlekelwa kwe-splice ngokuvamile kungu-0.3dB.Kodwa i-fiber mechanical splicing yethula ukuboniswa okuphezulu kunezindlela zokuhlanganisa i-fusion.
I-optical cable mechanical splice incane, kulula ukuyisebenzisa, futhi ilungele ukukhanda ngokushesha noma ukufakwa unomphela.Zinezinhlobo ezihlala njalo nezingeneka kabusha.Izintambo zemishini ye-Optical cable ziyatholakala kumodi eyodwa noma i-multi-mode fiber.
Ukuhlanganiswa kwe-Fusion
I-Fusion splicing ibiza kakhulu kunokuhlanganisa ngomshini kodwa ihlala isikhathi eside.Indlela ye-fusion splicing ihlanganisa ama-cores ngokuncishiswa okuncane.(ukulahlekelwa kokufakwa <0.1dB)
Ngesikhathi senqubo yokuhlanganisa, i-fusion splicer ezinikele isetshenziswa ukuqondisa kahle iziphetho ezimbili zefayibha, bese iziphetho zengilazi "zihlanganiswe" noma "zishiselwe" ndawonye kusetshenziswa i-arc kagesi noma ukushisa.
Lokhu kudala ukuxhumana okusobala, okungabonisi, nokuqhubekayo phakathi kwamafayibha, okuvumela ukudluliswa kwe-optical okulahlekelwa kancane.(Ukulahlekelwa okujwayelekile: 0.1 dB)
I-fusion splicer yenza i-optical fibre fusion ngezinyathelo ezimbili.
1. Ukuqondanisa okunembile kwemicu emibili
2. Dala i-arc encane ukuze uncibilikise imicu futhi uyihlanganise ndawonye
Ngokungeziwe ekulahlekeni kwe-splice okujwayelekile okuphansi okungu-0.1dB, izinzuzo ze-splice zifaka phakathi ukuboniswa okungemuva okumbalwa.
