Ka lebaka la bandwidth e phahameng le phokotso e tlase e tlisoang ke fiber ea optical, lebelo la marang-rang le ntse le eketseha haholo. Theknoloji ea transceiver ea fiber optic le eona e ntse e fetoha ka potlako ho fihlela litlhoko tse ntseng li eketseha tsa lebelo le bokhoni. A re shebeng kamoo tsoelo-pele ena e tla ama litsi tsa data kateng.
Faebatransceiver ea opticke potoloho e kopaneng (IC) e ka fetisang le ho amohela data ka boikemelo mahlakoreng ka bobeli. Sesebelisoa sena se kopanya transmitter le receiver ho ba mojule o le mong o fetolang matshwao a motlakase hore e be matshwao a optical, e leng se nolofalletsang matshwao ana ho fetisetswa ka katleho ho tloha ho seva ho ya ho seva ka dithapo tsa fiber optic.
The bafetoleli ba phetisetsoho kenngwa ha motlakase tlhahisong ya optical ho tswa ho diode ya laser kapa mohlodi wa lesedi la LED (lesedi le kopanngwa le faeba ya optical ka sehokelo mme le fetisetswa ka thapo ya optic ya fiber). Lesedi le tswang pheletsong ya faeba le kopanngwa le moamoheli, mme sesebediswa sa ho lemoha se fetola lesedi hore e be letshwao la motlakase, le hlophisitsweng hore le sebediswe ke sesebediswa se amohelang. Ke eng e ka hare ho transceiver ya optic ya fiber?
Li-transceiver tsa faeba ea optical li na le li-transmitter, li-receiver, lisebelisoa tsa optical le li-chip. Hangata chip e nkoa e le pelo ea module ea fiber optic. Lilemong tsa morao tjena, ho bile le thahasello e ntseng e hola ea ho sebelisa li-photonic tsa silicon ho li-chip tsa transceiver - ho haha li-laser ho silicon ebe ho kopanngoa likarolo tsa optical ka lipotoloho tse kopantsoeng tsa silicon. E sebetsana le tlhoko ea likhokahano tse potlakileng ho tloha rack ho ea rack le ho pholletsa le litsi tsa data. E nolofatsa ts'ebetso ea kopano ka katleho. Ho phaella moo, li-transceiver li ka etsoa hore li be nyane haholoanyane, li fokotsa sebaka sa seva ka kakaretso 'me li nolofalletse litsi tse nyane tsa data tse sa tebang ha li ntse li boloka bongata bo phahameng ba port. Ka lehlakoreng le leng, boholo bo bonyenyane bo bolela tšebeliso e fokolang ea matla le litšenyehelo tse tlase.
Histori e Khutšoanyane ea Bafetoleli ba Optical
Ho amoheloa ha theknoloji ea silicon photonics ka har'a li-transceiver chips ke bopaki bo bong ba tsoelo-pele e kholo theknolojing ea transceiver ea fiber-optic. Mokhoa ke hore li-transceiver tsa fiber optic li ntse li leba boholo bo bonyenyane le litefiso tse phahameng tsa data ho amohela keketseho ea sephethephethe sa data se bakiloeng ke phetohelo ea Inthanete.
