Na li-transceivers tsa fiber optic li tlameha ho sebelisoa ka bobeli?Na ho na le karohano ho transceiver ea fiber?Kapa ho ka sebelisoa feela para ea fiber optic transceivers ho etsa para? Haeba li-transceivers tsa fiber li tlameha ho sebelisoa ka bobeli, na ehlile ke mofuta le mohlala o tšoanang? Kapa na u ka sebelisa motsoako ofe kapa ofe oa lihlahisoa?
Karabo: Li-transceivers tsa optical hangata li sebelisoa ka bobeli e le lisebelisoa tsa ho fetola photoelectric. Leha ho le joalo, hoa khoneha ho sebelisa li-transceivers tsa optical le fiberli-switches, li-transceivers tsa fiber le li-transceivers tsa SFP. Ha e le hantle, hafeela maqhubu a phetisetso ea optical a ntse a tšoana, puisano ea Fiber-optic e ka finyelloa ka mokhoa o ts'oanang oa ho kenyelletsa letšoao le ho tšehetsa protocol e itseng.
Ka kakaretso, li-transceivers tsa li-fiber tse peli (li-fiber tse peli tse hlokahalang bakeng sa puisano e tloaelehileng) ha li aroloe qetellong ea phetisetso le qetello ea ho amohela. Ke transceiver ea fiber e le 'ngoe feela (e hlokang tlhale e le 'ngoe bakeng sa puisano e tloaelehileng) e tla ba le pheletso ea phetiso le pheletso ea ho amohela.
Hore na ke transceiver ea li-faeba tse peli kapa transceiver ea fiber e le 'ngoe, e lumellana le ho sebelisa mefuta e fapaneng ka bobeli. Leha ho le joalo, litekanyetso tse fapaneng (100 megabits le gigabytes) le maqhubu a fapaneng a fapaneng (1310 nm le 1300 nm) ha li tsamaisane. Ho phaella moo, esita le transceiver ea fiber e le 'ngoe ea mofuta o le mong le para ea li-dual-fiber le tse peli tsa fiber ha li khone ho sebelisana.
Transceiver e nang le fiber tse peli e na le boema-kepe ba TX (boema-kepe bo fetisang) le boema-kepe ba RX (boema-kepe bo amohelang). Likou tsena ka bobeli li ntša bolelele bo lekanang ba 1310 nm, 'me ho amohela ho boetse ho na le 1310 nm, kahoo likhoele tse peli tse tšoanang li hokahane ka khokahanyo ea sefapano. . E sebelisa theknoloji ea "wavelength division multiplexing" ho fetisa le ho amohela lipontšo tse peli tsa optical tsa wavelengths tse fapaneng holim'a fiber e le 'ngoe ea optical. Ka kakaretso ba sebelisa wavelengths ea 1310 nm le 1550 nm.
Mefuta e fapaneng ea li-transceivers tsa optical e tšehetsa liprothokholo tsa Ethernet. Ba ka buisana le li-transceivers tsa litlhaloso tse tšoanang, empa li-transceiver tse ling li eketsa mesebetsi e itseng (joaloka seipone) le ho tšehetsa mekhoa e meng. Tabeng ea nyeoe ha e tšehetsoe.
