    Chronicle na ci gaban Tantancewar fiber sadarwa tsarin

    Lokacin aikawa: Agusta-30-2019

    Tare da ci gaba da haɓaka fasahar sadarwa ta gani, sadarwar fiber na gani ta ɗanɗana ƙarni biyar tun bayan bayyanarsa. An samu ingantawa da haɓakawa na OM1, OM2, OM3, OM4 da OM5 fiber, kuma ya ci gaba da ci gaba da ci gaba a cikin iyawar watsawa da watsawa. Saboda halaye da yanayin aikace-aikacen, OM5 fiber ya nuna kyakkyawan ci gaba.

    Tsarin sadarwar fiber na gani na ƙarni na farko

    1966-1976 shine matakin ci gaba na fiber na gani daga bincike na asali zuwa aikace-aikacen aiki. A wannan mataki, tsarin sadarwa na fiber na gani na multimode (0.85μm) tare da gajeren zangon 850nm da 45 MB / s, 34 MB / s low rate an gane. A cikin yanayin amplifier, nisan watsawa zai iya kaiwa 10km.

    Tsarin sadarwa na fiber na gani na ƙarni na biyu

    A cikin 1976-1986, makasudin bincike shine don haɓaka ƙimar watsawa da haɓaka nisan watsawa, da haɓaka haɓaka haɓaka matakin aiwatar da tsarin sadarwa na fiber na gani. Tsawon zangon aiki kuma ya haɓaka daga 850nm ɗan gajeren zango zuwa 1310nm/1550nm tsayin tsayin igiyar ruwa, yana samun tsarin sadarwar fiber guda ɗaya tare da saurin watsawa na 140 ~ 565 Mb/s. A cikin yanayin amplifier, nisan watsawa zai iya kaiwa 100km.

    Tsarin sadarwa na fiber na gani na ƙarni na uku

    Daga 1986 zuwa 1996, an gudanar da ci gaban bincike na iya aiki mai girma da nisa mai tsayi don nazarin sabuwar fasahar fiber na gani. An aiwatar da tsarin sadarwa na fiber na gani guda ɗaya na 1.55 μm a wannan matakin. Fiber yana amfani da dabarar daidaitawa ta waje (na'urar gani ta lantarki) tare da saurin watsawa har zuwa 10 Gb/s da nisan watsawa har zuwa kilomita 150 ba tare da amplifier ba.

    1996-2009 shine zamanin daidaita tsarin dijital na hanyar sadarwa na fiber na gani. Tsarin sadarwa na fiber na gani yana gabatar da amplifiers na gani don rage buƙatar masu maimaitawa. Ana amfani da fasahar multixing rabon tsayin tsayi don haɓaka ƙimar watsa fiber na gani (har zuwa 10Tb/s) da nisan watsawa. Zai iya kai har zuwa 160km.

    Lura: A cikin 2002, ISO/IEC 11801 a hukumance ya ƙaddamar da daidaitaccen nau'in fiber multimode, yana rarraba fiber multimode OM1, OM2 da OM3 fiber. A cikin 2009, TIA-492-AAAD a hukumance ta ayyana fiber OM4.

    Tsarin sadarwa na fiber na gani na ƙarni na biyar

    Tsarin sadarwa na fiber na gani yana gabatar da fasahar soliton na gani, kuma yana amfani da tasirin fiber ɗin da ba a taɓa gani ba don sa igiyar bugun jini ta yi tsayayya da tarwatsewa a ƙarƙashin ainihin waveform. A wannan mataki, tsarin sadarwa na fiber-optic ya sami nasarar faɗaɗa tsawon zangon raƙuman ruwa na multixer, kuma ainihin 1530nm ~ 1570 nm ya kai 1300 nm zuwa 1650 nm. Bugu da ƙari, a wannan mataki (2016) OM5 fiber an ƙaddamar da shi bisa hukuma.
