Leraele la fiber optic ke mochine oa marang-rang o nang le lisebelisoa tsa likhalase tsa khalase kahare ho khalase ea mashala. Li etselitsoe marang-rang a malelele, marang-rang a phahameng a sebetsang ka marang-rang, le lithelefono.
Ha li bapisoa le lisebelisoa tse tsomang, lisebelisoa tsa fiber optic li fana ka bophahamo bo bongata bo phahameng 'me li ka fetisetsa data ka libaka tse telele.
Likhoele tsa fiber optic li tšehetsa boholo ba inthanete ea lefatše, thelevishene le thelefono ea thelefono.
Kamoo Cerepo ea Fiber Optic e sebetsang kateng
Lisebelisoa tsa fiber optic li jara lipontšo tsa puisano ho sebelisa likhase tsa leseli tse hlahisoang ke li-lasers tse nyenyane kapa li-LED tse khanyang.
Mohala o na le khalase e le 'ngoe kapa ho feta, e' ngoe le e 'ngoe e thibela ho feta moriri oa motho. Setsi sa mokopa o mong le o mong se bitsoa mokokotlo, o fanang ka tsela ea leseli la ho tsamaea. Motsoako o pota-potiloe ke karolo ea khalase e bitsoang ho roala e bontsang leseli ka hare ho qoba tahlehelo ea letšoao le ho lumella leseli hore le fete ka likhahla ka mohala.
Mefuta e 'meli e meholo ea lisebelisoa tsa thepa e bitsoa mefuta e le 'ngoe feela ea fiber. Single fiber fiber e sebelisa lisebelisoa tse fokolang tsa khalase le laser ho hlahisa leseli ha mefuta e mengata e sebelisa li-LED.
Mekhoa e metle ea fiber ea marang-rang e atisa ho sebelisa mekhoa ea Wave Division Multiplexing (WDM) ho eketsa lenane la sephethephethe se ka tsamaisoang hohle. WDM e lumella khanya ka makhetlo a sa tšoaneng a wavelengths hore a kopane (multiplexed) mme a arohane hamorao (de-multiplexed), ka tsela e atlehang ho fetisetsa melaetsa e mengata ea puisano ka tsela e le 'ngoe ea khanya.
Melemo ea Likhoele tsa Fiber Optic
Lisebelisoa tsa fiber li fana ka menyetla e 'maloa ho feta moetlo oa koporo oa koporo oa khale.
- Fiber optics e na le bokhoni bo phahameng. Boima ba marang-rang a marang-rang a thepa ea lisebelisoa e ka tsamaisa habonolo ho feta ea koporo ea koporo e nang le boholo bo tšoanang. Lisebelisoa tsa fiber li lekantsoeng ka 10 Gbps, 40 Gbps esita le 100 Gbps ke maemo a tloaelehileng.
- Kaha leseli le ka tsamaea maeto a malelele haholo ho theosa le khoele ea fiber ntle le ho lahleheloa ke matla a lona, e fokotsa tlhokahalo ea ho matlafatsa lipontšo.

Ha ts'ireletso ena e thusa, ha e lekane ho thibela ho sitisoa ha lithapo tse ngata li kopane hammoho haufi le e mong. Matla a khalase le a fiber a qoba boholo ba lintlha tsena.
Fiber to Home (FTTH), Tse ling tsa Ts'ebetso, le Fiber Networks
Le hoja li-fiber tse ngata li kenngoa ho tšehetsa maqhama a malelele a metse le linaha, bahlahisi ba bang ba marang-rang ba lits'ebeletso tsa marang-rang ba sebelisitse ho eketsa lisebelisuoa tsa bona ho metse e haufi le metse e meholo bakeng sa ho fihlella ka ho toba ke malapa. Bahlahisi le litsebi tsa indasteri ba bitsa mekhoa ena ea "maeto a ho qetela".
Tse ling tsa litšebeletso tse tsebahalang ka FTTH 'marakeng kajeno li kenyelletsa Verizon FIOS le Google Fiber. Litšebeletso tsena li ka fana ka sekhahla sa inthanete sa gigabit (1 Gbps) ho ntlo ka 'ngoe.
