Unxibelelwano lwe-Optical fiber yeyona ndlela iphambili yothumelo lothungelwano lwale mihla.Imbali yophuhliso yiminyaka enye okanye amabini kuphela.Ifumene izizukulwana ezithathu: i-fiber ye-multimode ye-wavelength emifutshane, i-multi-wavelength ye-multimode fiber kunye ne-long-wavelength ye-fiber enye.Okwangoku, unxibelelwano lwaseTshayina lwefiber optical lungene kwinqanaba elisebenzayo.Ukongeza, amazwe amaninzi abhengeze ukuba akasayi kuphinda akhe iintambo zonxibelelwano lwentambo kwaye azibophelele ekuphuhliseni unxibelelwano lwefiber optical.
Intshayelelo kuNxibelelwano lweFayibha ye-Optical
Into ebizwa ngokuba yi-optical fiber communication isebenzisa i-fiber optical ukuhambisa amaza okukhanya athwele ulwazi ukufezekisa iinjongo zonxibelelwano.Ukuze wenze i-wave yokukhanya i-carrier ephethe ulwazi, kufuneka iguqulwe, kwaye ulwazi lufunyenwe kwi-wave wave ekufumaneni i-teknoloji, i-optical fiber communication inembali ye-30 ukuya kwi-40 iminyaka, kodwa ine-. itshintshe ngokupheleleyo ubuso bonxibelelwano lwehlabathi, kwaye uphuhliso lwalo lwexesha elizayo alunakulinganiswa.
Umgaqo wonxibelelwano lwefiber optical kunye nokuhanjiswa
Umgaqo wonxibelelwano lwefiber optical: ekupheleni kokudlulisa, ulwazi oludlulisiweyo (njengelizwi) luguqulwa kuqala lube ngumqondiso wombane, emva koko lumodareyithwe kumqadi welaser okhutshwa yilaser, ukuze ubunzulu bokukhanya butshintshe i-amplitude (i-frequency) yesiginali yombane, kwaye Thumela ngefiber.Ekupheleni kokufumana, i-detector ifumana isignali ye-optical kwaye iguqule ibe ngumqondiso wombane, oye wachithwa ukubuyisela ulwazi lokuqala.
Inzuzo
(1) Umthamo wonxibelelwano mkhulu kwaye umgama wothumelo mde.
(2) Ilahleko yefiber iphantsi kakhulu.
(3) Ukuphazamiseka komqondiso omncinci kunye nobumfihlo obuhle.
(4) Ukuphazamiseka kweAnti-electromagnetic, umgangatho olungileyo wokuhambisa.
(5) Ifiber incinci ngobukhulu kwaye ilula ngesisindo, ekulula ukuyibeka kunye nokuthutha.
(6) Ubutyebi bezinto eziphathekayo kunye nokukhuselwa kwendalo, kukulungele ukugcina ubhedu lwesinyithi olungenantsimbi.
(7) Akukho mitha, kunzima ukuyiva.
(8) Intambo inokuguquguquka okuqinileyo kunye nobomi obude.
Ukusilela
(1) Ubume bubuthathaka kwaye amandla omatshini abuthathaka.
(2) Ukusikwa kunye nokudityaniswa kwee-optical fibers kufuna izixhobo ezithile, izixhobo kunye nobuchule.
(3) Ukwahlula kunye nokudibanisa akukho bhetyebhetye.
(4) Iradiyasi yokugoba yentambo yefiber optic akufanele ibencinci kakhulu (>20cm).
(5) Kukho ingxaki ngombane wobunzima.
Uqikelelo lophuhliso lonxibelelwano lwefiber optical
Kule mihla, umthamo wentengiso yezixhobo zonxibelelwano zefiber optical kunye nentambo ye-optical e-China iyanda minyaka le.Kwiindawo ezininzi zasemaphandleni kumaphondo amaninzi kunye nezixeko zaseChina, ukwakhiwa konxibelelwano lweselula kusekho into engenanto.Ukongeza, ngophuhliso lweenkonzo zebroadband kunye nesidingo sokwandiswa kwenethiwekhi, unxibelelwano lwefiber optical kwixesha elizayo Imarike inkulu.
