The fiber hab kaliya oo multimode duwan

Marka ay timaado in gudbinta xogta ka hal meel fog fog si kale, sii kordhaya halkii silig copper dhaqanka in qandaraaslayaasha macaamiisha martiqaaday in ay gacmo-ka cable ee indhaha. About this technology xiiso leh waxaan leenahay maanta iyo ayaan ka hadli doonaa.

line isgaadhsiinta Fiber-optic (FOL) ku shaqeeyaan on mabda'a ah ee la isugu gudbiyo ee hirarka iftiinka by channels gaarka ah ee galaas quartz aadka saafi ah ka sameeyey. falalkooda korontada ee qalabka elektarooniga ah la siiyo Converter signal ah, taas oo abuuraa durdur la karsado iftiinka iyo iyaga gudbiya si cable ka. Dhamaadka kale ee qaata iftiin helo durdur iyo waxa transcodes dib u karsado electromagnetic. Sababtoo ah nidaamka oo dhan waxaa si elektaroonig ah gacanta iyo waa qaab beddelidda digital, dhalanrog hooseeyo.

In la dhiso rakibayo sida, isticmaalaan qalab gaar ah - fiber-hal hab oo multimode.

Khadadka Optic ahaayeen si baahsan, ma aha oo kaliya ay sabab u la'aanta ah ee faragelinta la isugu gudbiyo ee signalka. Ka mid ah faa'iidooyinka kama taagna of technology tani waa band ballaaran, attenuation a signal aad u tabar daran, iska caabin unsurpassed in wixii faragelin ah ee dabiiciga ah electromagnetic, kala duwan ee la isugu gudbiyo weyn, samaynta tobanaan badan oo kiilomitir. Faa'iidada A weyn waa adeegga isgaarsiinta muddo dheer, iyadoo la isticmaalayo dhigay rakibayo ah, in ugu yaraan 25 sano.

nooc oo fiber

Marka links kordhaya isticmaalaya khadka fiber-optic la doorto ama multimode ama hal fiber mode.

Waa maxay cable this? muhimka ah ee fiber waa quartz, galaas ultrapure, kaas oo sidoo kale maraa dogob iftiinka. A xereen ma dhicin waayo index Refractive qolof hoose ka badan asaasiga ah, haddaba sidaas daraaddeed, dogobka iftiinkooda waa loo gebi ahaanba ka muuqataa ka derbiyada gudaha fiber ah.

Multimode si fiican si ay u ordi karaan dhawr boqol oo hababka light in lagu bilaabaa at xaglo kala duwan. hab kasta wuxuu leeyahay jidka u gaar ah iyo, sida natiijo ah, markii ugu faafinta gaar ah.

khasaare ugu weyn ee noocan ah fiber - firidhsan hab, oo cidhiidhi ku bandwidth iyo xaddidaya oo dhererkiisu line ugu badnaan. Laliska for khadadka isgaarsiinta multimode sida caadiga ah waa meel fog ka ugu badan ee ku saabsan 5 kilomitir.

Dhibaatada of yaraynta kala firidhsan hab go'aan ka cable la profile a Wehliyaha Refractive index of xudunta u ah. fiber Tani, in la barbardhigo caadiga ah index fursadaha fursadaha Refractive hoos ka core xarunta si ay qolof ah, taas oo ku siinayaa horumar weyn ku soo koobin ee signalka kala qaado.

fiber The hab keli ah loogu talagalay, oo ku salaysan hawsha maraa channel isgaarsiinta ah oo kaliya hal hab (asaasiga ah). Habkan waxay leedahay faa'iidooyin badan. sifooyinka Qaar ka mid ah in cable ka, ee technology-hal hab, amar of magnitude ka khayr badan in laga soo saaro by multimode sameeyey. Tani waa arrin ay muhim u saameeya doorashada ay guushu ku ah injineerada ugu horeeyay ee gacmo-links cusub fiber optic. Indeed, fiber-hal hab siisaa attenuation at 0,25db halkii kiiloomitir, iskuna waxaa ka mid ah waa mid aad u yar yar iyo bandwidth ballaaran bixisaa gudbinta cad oo deg deg ah ee xaddi badan oo data oo aan dhalanrog.

Laakiin waxaa jira in Daqsi cadar in cadar ah. Noocani waa nooc aad uga qaalisan tahay fiber multimode. Tan iyo markii size ee diirkja light-ku hogaamiyay in hal-cable waa mid aad u yar, talooyin shucaaca ee cable noocan oo kale ah waa adag oo u baahan gacanta aad ka taxadartaa in splicing. Xidhiidhiyayaasha dhamaadka ee khadadka iyo aad bay uga qaalisan tahay khadadka kontseviki multimode. Intaa waxaa dheer, dambe ay sabab u tahay xog ah ee talooyinka ku jirase aad iftiin baa core ballaaran oo aad u fudud, cheap laliska, kaas oo sidoo kale soo saaray tiro badan ka mid ah shirkadaha ku tartamaya.
