Faeba optic konokono ponahatso teko

Faeba optic konokono ponahatso teko e tsoela pele ke Optical Nako Domain Reflectometer (OTDR). E leng sesebelisoa se sebelisetsoang ho lemoha liphoso khokahanong ea fiber ea marang-rang a likhokahano tsa puisano. OTDR e hlahisa pulse kahare ho faeba e tla hlahlojoa liphoso kapa liphoso. Liketsahalo tse fapaneng kahare ho fiber li baka ho hasana ha Rayleigh. Li-pulse li khutlisetsoa ho OTDR 'me matla a tsona a lekantsoe ebe a baloa e le tšebetso ea nako ebe a raloa joalo ka ts'ebetso ea fiber. Matla le lets'oao le khutlisitsoeng le bolela ka sebaka le matla a phoso e teng. Ha se tlhokomelo feela, empa le lits'ebeletso tsa ho kenya line ea optical li sebelisa li-OTDR.

OTDR e na le thuso bakeng sa ho leka botšepehi ba likhoele tsa fiber optic. E ka netefatsa tahlehelo ea splice, lekanya bolelele le ho fumana liphoso. OTDR e boetse e tloaetse ho sebelisoa ho etsa "setšoantšo" sa fiber optic cable ha e sa tsoa hlongoa. Hamorao, papiso e ka etsoa lipakeng tsa trace ea mantlha le mohlala oa bobeli o nkuoeng ha ho hlaha mathata. Ho sekaseka tatellano ea OTDR kamehla ho nolofatsoa ka ho ba le litokomane tse tsoang mosaleng oa mantlha o ileng oa etsoa ha thapo e ne e kengooa. OTDR e bonts'a moo likhoele li felisitsoeng teng mme e netefatsa boleng ba likhoele, likhokelo le likhechana. Lits'oants'o tsa OTDR le tsona li sebelisetsoa ho rarolla mathata, hobane li ka bonts'a moo likheo li leng fiber ha litepisi li bapisoa le litokomane tsa ho kenya.

Jera a tsoela pele ho etsa liteko tsa lisebelisoa tsa lerotholi tsa FTTH ho wavelengths (1310,1550 le 1625 nm). Re sebelisa OTDR YOKOGAWA AQ 1200 litekong tsena tsa boleng. Ho lekola boleng ba likhoele tsa rona ho netefatsa hore moreki oa rona o ka fumana lihlahisoa tse fihlelang litlhokahalo tsa boleng.

Re etsa teko ena likhoebong tsohle tseo re li hlahisang.
Laboratori ea rona ea kahare e khona ho tsoela pele ka letoto la liteko tse amanang le mofuta.
Rea u amohela ho ikopanya le rona bakeng sa tlhaiso-leseling e batsi.
