Mabda'a isgaarsiinta indhaha
Mabda'a isgaarsiineed waa sida soo socota. Dhamaadka dirista, macluumaadka la gudbiyo (sida codka) waa in marka hore loo beddelaa calaamadaha korantada, ka dibna calaamadaha korantada ayaa loo beddelaa laydhka laysarka ee uu sii daayo laser (Isha iftiinka), si iftiinka iftiinka wuxuu ku kala duwan yahay xajmiga (soo noqnoqda) calaamadaha korantada iyo iyada oo loo marayo mabda'a guud ee iftiinka iftiinka, calaamadda indhaha ayaa lagu kala qaadaa fiber-ka indhaha. la yareeyey oo la qalloociyey ka dib markii lagu kala qaado meel fog.Digniinta la dhimay waxaa lagu xoojiyey dib-u-celinta indhaha si loo hagaajiyo mawjada qalloocan.Dhammaadka helitaanka, baaraha wuxuu helayaa calaamadda indhaha wuxuuna u beddelaa signalka korantada, kaas oo la dhimay si loo soo celiyo macluumaadka asalka ah.
Faa'iidooyinka gudbinta fiber indhaha:
● Awood isgaarsiineed oo weyn, fogaan isgaarsiineed oo dheer, dareen sare, iyo wax faragelin ah oo aan buuq lahayn
● Cabbir yar, miisaan fudud, cimri dheer, tayo wanaagsan iyo qiimo jaban
● Dahaarka, caabbinta cadaadiska sare, heerkulka sare, daxalka, la qabsiga xooggan
● Sirta sare
●Alaabaha ceeriin ee hodanka ah iyo awoodda hoose: Waxyaabaha ugu badan ee ceyriinka ah ee lagu sameeyo fiber quartz waa silica, taas oo ah ciid, ciiduna waa badan tahay.
Isgaadhsiinta fibre-gaabku waxa ay ka kooban tahay taxane isgaadhsiineed oo indhaha ah.Dabiici ahaan, qiimaheedu wuu hooseeyaa.Aaladaha indhaha waxa loo kala saaraa aaladaha firfircoon iyo aaladaha dadban. Calaamadaha korantada oo loo beddelo signalka indhaha ama u beddela signalka indhaha oo u beddela calaamad koronto, waana wadnaha nidaamka gudbinta indhaha. beddelidda indhaha.Waa qanjidhada muhiimka ah ee hababka gudbinta indhaha, oo ay ku jiraan isku xidhayaasha fiber optic, kala qaybinta indhaha, iyo furayaasha indhaha., wareegayaasha indhaha iyo go'doominta indhaha.
Xadhkaha Fiber optic-ga (sidoo kale loo yaqaanno fiber optic connectors) waxay u jeedaan xidhidhka labada daraf ee fiilada si aad u hesho xidhiidh firfircooni leh. Fure hal daraf ah ayaa loo yaqaan pigtail.
●Wavelength division multiplexer (WDM) wuxuu isku daraa calaamado muuqaal ah oo taxane ah oo leh mawjadaha dhaadheer ee kala duwan wuxuuna ku kala qaadaa hal fiber indhaha ah.Farsamo isgaarsiineed kaas oo calaamadaha indhaha ee hirarka dhaadheer ee kala duwan ay u kala soocaan siyaalo qaarkood marka la gaaro dhamaadka.
● Kala qaybinta indhaha (sidoo kale loo yaqaan splitter) waa aaladda fiber-optic tandem oo leh qalabyo badan iyo wax soo saar badan. Sida ku cad mabda'a kala qaybinta, kala qaybinta indhaha waxaa loo qaybin karaa laba nooc: nooca dhalaalsan iyo nooca waveguide planar (planar waveguide). Nooca PLC).
● Furaha indhaha waa aaladda beddelka indhaha, kaas oo ah aaladda indhaha oo leh hal ama dhowr dekedood oo ikhtiyaari ah.Shaqadeedu waa inay jir ahaan u beddesho ama si macquul ah ugu shaqeyso calaamadaha indhaha ee xadhkaha gudbinta indhaha ama waddooyinka isku dhafan ee indhaha.
●Xeeldheeraha indhaha waa aalad indho-indhayn badan oo dekeddo leh oo leh astaamo aan is-dhaafsaneyn.
● Marka ishaarka indhaha laga soo galo deked kasta, waxa laga soo saaraa dekedda ku xigta iyada oo khasaare yar ay u kala horreeyaan.Haddii signalku ka soo galo dekedda 1, waxa kaliya oo laga soo saari karaa dekedda 2. Sidoo kale, haddii calaamaduhu ka soo galo dekedda 2, waxay ka soo bixi kartaa oo keliya dekedda 3.
● Go'doominta indhaha waa qalab indho-indheyn ah oo u oggolaanaya iftiinka aan jihayn oo keliya inuu dhex maro oo ka ilaaliya inuu u gudbo jihada ka soo horjeeda.Mabda'a shaqadeedu waxay ku salaysan tahay is-beddel la'aanta wareegtada Faraday.
