Unxibelelwano lweFayibha ye-Optical
Itekhnoloji yonxibelelwano lwefiber optical iye yavela kunxibelelwano lwe-optical kwaye iye yaba yenye yeentsika eziphambili zonxibelelwano lwanamhlanje.Idlala indima ebalulekileyo kuthungelwano lwezonxibelelwano lwanamhlanje.Njengobuchwepheshe obukhulayo, unxibelelwano lwefiber optical luye lwaphuhliswa ngokukhawuleza kwiminyaka yamuva kwaye lusetyenziswa ngokubanzi kwimbali yonxibelelwano.Ikwaluphawu olubalulekileyo lwenguqu entsha yetekhnoloji yehlabathi kunye nesixhobo esiphambili sothumelo lolwazi olwahlukeneyo kuluntu lolwazi lwexesha elizayo.
Iimpawu zonxibelelwano lwefiber optical
1.Umthamo wolwazi weBroadband mkhulu
Umthamo wonxibelelwano lwefiber optical bukhulu, kwaye ububanzi bokuhanjiswa kwefiber optical bukhulu kakhulu kunobubanzi bekhebula okanye ucingo lobhedu.Nangona kunjalo, kwi-single-wavelength optical fiber system, ekubeni isixhobo se-terminal silinganiselwe kakhulu, ububanzi bokuhanjiswa kwefiber optical kaninzi abubonakali.Ngoko ke, iindlela zenzululwazi ziyafuneka ukunyusa umthamo wosulelo.
2.Ilahleko ephantsi, inokudluliselwa kwimigama emide
Izinga lelahleko yonxibelelwano lwefiber optical lisezantsi kakhulu kunonxibelelwano oluqhelekileyo lwelahleko.I-fiber optical ayinayo ilahleko ephantsi kuphela, kodwa inokunxibelelana nemigama emide.Owona mgama mde wonxibelelwano ungafikelela ngaphezulu kwe-10,000 yeemitha, ngoko ke unxibelelwano lwefiber optical lusebenza ngakumbi kwiinethiwekhi zentlalo.Indawo apho isixa solwazi sithelekiseka khona kunye neendleko zonxibelelwano lwefiber-optic ziphezulu ngokwentelekiso, ngokhuseleko olulungileyo.
3.Ukuphazamiseka okunamandla okuchasana nombane
Ifayibha yamehlo ubukhulu becala yimathiriyeli ye-insulator eyenziwe ngequartz njengemathiriyeli ekrwada, kwaye imathiriyeli igqwesileyo kwi-insulation kwaye ayibikho lula.Olona phawu lubalulekileyo lonxibelelwano lwefiber optical lubuchule bayo obuqinileyo bokuchasana nombane wombane, kwaye akunjalo. ichaphazeleka ngumsebenzi we-sunspot yendalo, utshintsho lwe-ionospheric kunye nokuphazamiseka kombane, kwaye ayixhomekeke ekuphazamisekeni kwe-electromagnetic eyenziweyo.Kwaye unxibelelwano lwefiber optical lunokudibaniswa kunye nomqhubi wamandla ukwenza intambo ye-optical ephindwe kabini okanye ihambelane ne-high-voltage. intambo yamandla.Olu phawu lonxibelelwano lwefiber optical ludlala indima enkulu kwinkqubo yonxibelelwano kwintsimi yamandla ombane anamandla.Unxibelelwano lwamandla okukhanya lunokusetyenziswa emkhosini kuba lunokukhululeka kuphazamiseko lwe-electromagnetic pulse.
4.Ukhuseleko olulungileyo kunye nemfihlo
Kusasazo lwamaza onomathotholo kwixesha elidlulileyo, ekubeni amaza ombane evuza ngexesha lenkqubo yothumelo, ukuphazamiseka kweenkqubo ezahlukeneyo zokusasaza kubangelwa, kwaye ubumfihlo abuyonto intle.Nangona kunjalo, unxibelelwano lwefiber optical ikakhulu lusebenzisa amaza okukhanya ukuhambisa imiqondiso.Iimpawu ze-optical zivalelwe ngokupheleleyo kwisakhiwo se-waveguide optical, kunye neminye imisebe evuzayo ifunxwe yi-sheath yangaphandle ye-fiber optical, nakwindandatho enemeko embi okanye ikona.Kukwakho nokuvuza kwamaza okukhanya ambalwa.Ngaphezu koko, kwinkqubo yonxibelelwano lwefiber optical, ezininzi iintambo zefiber optical zingafakwa kwintambo enye ngaphandle kokuphazamiseka.Ke ngoko, unxibelelwano lwefiber optical lunamandla okuthintela ukuphazamiseka kunye nobumfihlo, kwaye ukusebenza kokhuseleko lonxibelelwano lwefiber optical nako kuphezulu kakhulu.
