I-Optical fiber iyifayibha eyenziwe ngengilazi noma ngepulasitiki, futhi i-fiber ngokwayo intekenteke kakhulu futhi iphuka kalula. Futhi ukufaka i-fiber encane ejazini lepulasitiki kuyivumela ukuthi igobe ngaphandle kokuphuka. Ikhebula elinefiber optical esongwe ngejazi eliyisivikelo yikhebula le-optical. Ingabe intambo yokubona ingagotshwa ngokuthanda kwakhe?
Njengoba i-fiber izwela uma iqina, ukuyigoba kungabangela isignali yokubona ukuthi ivuze ku-fiber cladding, futhi njengoba ukugoba kuya ngokuya kukhuphuka, isignali yokubona izovuza kakhulu. Ukugoba kungase futhi kubangele ama-microcracks angalimaza unomphela umcu. Ukwengeza enkingeni, amaphuzu e-microflex anzima ukuwathola futhi adinga imishini yokuhlola ebizayo, okungenani amabhuloho adinga ukuhlanzwa noma ukushintshwa. Ukugoba i-fiber kungabangela ukuncipha kwefayibha. Inani lokuncipha ngenxa yokugoba ifayibha liyakhuphuka njengoba incipha irediyasi yokugoba. I-attenuation ngenxa yokugoba inkulu ku-1550 nm kunaku-1310 nm, futhi inkulu nakakhulu ku-1625 nm. Ngakho-ke, lapho ufaka ama-fiber jumpers, ikakhulukazi endaweni yokuhlanganisa ikhebula ephezulu, i-jumper akufanele igotshwe ngale kwe-radius yayo eyamukelekile yokugoba. Ngakho iyiphi irediyasi efanelekile yokugoba?
I-fiber bend radius iyi-engeli lapho i-fiber ingagotshwa ngokuphephile kunoma iyiphi indawo. I-fiber bending radii ihlukile kuzo zonke izintambo noma izintambo zokuchibiyela futhi ingahluka kuye ngohlobo lwekhebula noma indlela ekhiqizwa ngayo. Irediyasi yokugoba encane incike kububanzi nohlobo lwekhebuli yokubona, ngokuvamile ifomula iyasetshenziswa: irediyasi yokugoba encane = ububanzi obungaphandle bekhebuli yokubona x ukuphindaphinda kwekhebuli yokubona.
Izinga elisha le-ANSI/TIA/EIA-568B.3 lichaza amazinga amancane erediyasi egobile kanye namandla amakhulu okudonsa kanzima kwamakhebuli angama-50/125 micron kanye namakhebuli angama-62.5/125 micron fibre optic. Ubuncane berediyasi yokugoba izoncika kukhebuli ethile ye-fiber optic. Esimeni lapho kungekho ukungezwani, irediyasi egobayo yekhebula yokubona ngokuvamile akufanele ibe ngaphansi ngokuphindwe kashumi kunobubanzi obungaphandle (OD) bekhebula yokubona. Ngaphansi kokulayisha okuqinile, irediyasi egobayo yekhebula lokubona ububanzi obungaphandle bekhebula lokubona izikhathi eziyi-15. Amazinga omkhakha wezintambo zokuchibiyela ezijwayelekile zemodi eyodwa ngokuvamile acacisa irediyasi egobile ephindwe kayishumi yobubanzi obungaphandle bekhebuli efakwe ibhantshi noma amayintshi angu-1.5 (38 mm), kuye ngokuthi yikuphi okukhulu. Ifayibha ye-G652 evame ukusetshenziswa ine-radius egobile encane engu-30mm.
I-G657, esetshenziswe eminyakeni yamuva, inobubanzi obuncane bokugoba, okuhlanganisa i-G657A1, i-G657A2 ne-G657B3 I-radius encane yokugoba ye-G657A1 yi-10mm, i-G657A2 fiber yi-7.5mm, ne-fiber G657B3 yi-5mm. Lolu hlobo lwefayibha lusekelwe ku-G652D fiber, ethuthukisa izici zokugoba zokugoba nezici zejiyomethri zefayibha, ngaleyo ndlela ithuthukise izici zokuxhuma zefayibha, eyaziwa nangokuthi i-goba attenuation fiber engezwakali. Isetshenziswa kakhulu ku-FTTx, FTTH, ilungele ukusetshenziswa ezindaweni ezincane zasendlini noma emakhoneni.
Kokubili ukuphuka kwe-fiber kanye nokwenyuka kokuncipha kungase kube nomthelela omkhulu ekuthembekeni kwenethiwekhi yesikhathi eside, izindleko zokusebenza zenethiwekhi, kanye nekhono lokunakekela nokukhulisa isisekelo samakhasimende. Ngakho-ke, sidinga ukwazi ngokucacile i-radius encane yokugoba yefayibha ukuze sigcine intambo noma intambo yokuchibiyela isesimweni esihle sokusebenza.
