Ngophuhliso oluqhubekayo lwetekhnoloji yonxibelelwano lwamehlo, unxibelelwano lwefiber optical luye lwafumana izizukulwana ezihlanu ukususela ekubonakaleni kwayo. Kuye kwaphuculwa kunye nokuphuculwa kwe-OM1, i-OM2, i-OM3, i-OM4 kunye ne-OM5 ifayibha, kwaye yenze impumelelo eqhubekayo kumthamo wokuhambisa kunye nomgama wokudlulisa. Ngenxa yeempawu kunye neemeko zesicelo, i-OM5 fiber ibonise ukukhula okulungileyo.
Inkqubo yokuqala yonxibelelwano lwefiber optical
I-1966-1976 yayiyinqanaba lophuhliso lwefiber optical ukusuka kuphando olusisiseko ukuya kwisicelo esisebenzayo. Ngeli nqanaba, i-multimode (0.85μm) inkqubo yonxibelelwano lwefiber optical kunye ne-850nm ubude obufutshane kunye ne-45 MB / s, i-34 MB / s izinga eliphantsi liye laqatshelwa. Kwimeko yeamplifier, umgama wothumelo ungafikelela kwi-10km.
Isizukulwana sesibini inkqubo yonxibelelwano lwefiber optical
Kwi-1976-1986, injongo yophando yayikukuphucula izinga lokudluliselwa kunye nokwandisa umgama wokudluliselwa, kunye nokukhuthaza ngamandla isigaba sophuhliso lokusetyenziswa kweenkqubo zonxibelelwano ze-fiber optical. Kweli nqanaba, i-fiber yavela kwi-multimode ukuya kwimodi enye, kunye Ubude be-wavelength obusebenzayo buphuhliswe ukusuka kwi-850nm ubude obufutshane ukuya kwi-1310nm / 1550nm ubude be-wavelength, ukufezekisa inkqubo yonxibelelwano yefayibha enye kunye nesantya sokudluliselwa kwe-140 ~ 565 Mb / s. Kwimeko yeamplifier, umgama wothumelo ungafikelela kwi-100km.
Inkqubo yonxibelelwano lwefiber yesizukulwana sesithathu
Ukususela kwi-1986 ukuya kwi-1996, inkqubela yophando ye-ultra-enkulu kunye nomgama omde we-ultra-long yaqhutyelwa ukufunda iteknoloji entsha ye-fiber optical. Ukusasazwa kwe-1.55 μm kwatshintsha inkqubo yonxibelelwano yefiber optic enye yaphunyezwa kweli nqanaba. I-fiber isebenzisa i-modulation technique yangaphandle (isixhobo se-electro-optical) kunye nesantya sokudluliselwa ukuya kwi-10 Gb / s kunye nomgama wokuhambisa ukuya kwi-150 km ngaphandle kwe-amplifier yokubuyisela.
Inkqubo yesizukulwana sesine sonxibelelwano lwefiber optical
I-1996-2009 lixesha le-synchronous digital system optical transmission network. Inkqubo yonxibelelwano lwefiber optical yazisa i-optical amplifiers ukunciphisa imfuno yabaphindayo. I-teknoloji ye-multiplexing ye-wavelength ye-wavelength isetyenziselwa ukunyusa izinga lokuhanjiswa kwe-fiber optical (ukuya kwi-10Tb / s) kunye nomgama wokuhambisa. Inokufikelela kwi-160km.
Qaphela: Kwi-2002, i-ISO / IEC 11801 yazisa ngokusemthethweni iklasi esemgangathweni ye-multimode fiber, i-multimode fiber OM1, i-OM2 kunye ne-OM3 fiber. Kwi-2009, i-TIA-492-AAAD ichaze ngokusemthethweni i-OM4 fiber.
Inkqubo yesihlanu yonxibelelwano lwefiber optical
Inkqubo yonxibelelwano lwefiber optical yazisa itekhnoloji ye-soliton ye-optical, kwaye isebenzisa i-nonlinear effect yefiber ukwenza i-pulse wave ixhathise ukusabalalisa phantsi kwe-waveform yangaphambili. Kweli nqanaba, inkqubo yonxibelelwano ye-fiber-optic yandisa ngempumelelo i-wavelength ye-wavelength division multiplexer, kunye ne-1530nm yokuqala ~ I-1570 nm ifikelela kwi-1300 nm ukuya kwi-1650 nm. Ukongezelela, ngeli nqanaba (2016) i-OM5 fiber iqaliswe ngokusemthethweni.
