I-Waveband ye-fiber optical

Unxibelelwano lwefiber optical luthatha ukukhanya njengomphathi wolwazi ukunxibelelana.Inokudluliselwa nge-fiber core.Nangona kunjalo, asiyiyo yonke imisebe yokukhanya efanelekileyo kunxibelelwano.Ilahleko yothumelo iyahluka ngokwahlukeneyo ngamaza okukhanya.Ukufezekisa ilahleko encinci kunye nokusebenza ngokufanelekileyo, izazinzulu zihlala zikhangela ukukhanya okufanelekileyo.

850nm iWaveband

Ekuqaleni kwee-1980, izazinzulu zaqala ukuphonononga itekhnoloji yonxibelelwano lwefiber optical ngendlela esebenzayo.Iimowudi ezininzi zefiber yeyona nto babefunda ngayo.Ngamacores amakhulu efiber, i-muti-mode fiber iyakwazi ukubona ukuhanjiswa kwefayibha enye kwizibane ze-muti-mode.I-850nm yobude bokukhanya yayilelona lisetyenziswa kuqala.

O Waveband

Ekuqaleni kweminyaka yee-1990, ifayibha yendlela enye yaqala ukusetyenziswa ngokubanzi.

Umfanekiso woku-1

Iingcali zenzululwazi ziye zafumanisa ukuba ukukhanya kwe-waveband ye-1260nm ~ 1360nm kunokufezekisa ukuchithwa kwesignali encinci kunye nelahleko yokuhanjiswa okubangelwa ukusabalalisa ngokusebenzisa iimvavanyo.Ngoko ke, baqamba ezi zibane ze-waveband njenge-O-band kunye ne-"O" imele "i-Original".Ngeemvavanyo kunye nephutha, izazinzulu zafumanisa ukuba ukukhanya kunye ne-1260nm ~ 1625nm kwakhona kwindawo encinci yelahleko kwaye yeyona ndawo ifanelekileyo yokuhanjiswa kwefayibha.

I-1260nm ~ 1625nm i-waveband yokukhanya yahlulwe yaba yi-waveband ye-O ezintlanu, i-waveband ye-E, i-waveband ye-S, i-waveband ye-C kunye ne-L waveband.

Umfanekiso wesi-2

Izazinzulu zikwafumene ubudlelwane phakathi kwelahleko yosulelo kunye nobude bamaza.Ibonisa ngolu hlobo lulandelayo.
