Ndi chitukuko chosalekeza chaukadaulo waukadaulo wolumikizirana, kuwala kwa fiber kulumikizana kwakumana ndi mibadwo isanu kuyambira pomwe idawonekera. Yakhala ikukhathamiritsa ndikukweza kwa OM1, OM2, OM3, OM4 ndi OM5 fiber, ndipo yapanga zotsogola mosalekeza pakufalitsa mphamvu komanso mtunda wotumizira. Chifukwa cha mawonekedwe ndi mawonekedwe ogwiritsira ntchito, OM5 fiber yawonetsa kukwera bwino kwachitukuko.
M'badwo woyamba optical fiber communication system
1966-1976 inali gawo lachitukuko cha kuwala kwa fiber kuchokera ku kafukufuku woyambira mpaka kugwiritsa ntchito kothandiza. Pa nthawiyi, multimode (0.85μm) kuwala CHIKWANGWANI kulankhulana dongosolo ndi 850nm lalifupi wavelength ndi 45 MB/s, 34 MB/s otsika mlingo anazindikira. Pankhani ya amplifier, mtunda wotumizira ukhoza kufika 10km.
M'badwo wachiwiri optical fiber communication system
Mu 1976-1986, cholinga cha kafukufuku chinali kupititsa patsogolo kuchuluka kwa kufalitsa ndikuwonjezera mtunda wotumizira, ndikulimbikitsa mwamphamvu gawo lachitukuko la kugwiritsa ntchito makina opangira mauthenga opangidwa ndi kuwala. utali wogwiritsa ntchito wavelength unayambanso kuchokera ku 850nm lalifupi lalitali mpaka 1310nm / 1550nm kutalika kwa mawonekedwe, kukwaniritsa njira imodzi yolumikizira CHIKWANGWANI chokhala ndi kufalikira kwa 140 ~ 565 Mb / s. Pankhani ya amplifier, mtunda wotumizira ukhoza kufika 100km.
M'badwo wachitatu optical fiber communication system
Kuchokera ku 1986 mpaka 1996, kupita patsogolo kwa kafukufuku wa mphamvu zazikulu kwambiri komanso mtunda wautali kwambiri kunachitika kuti aphunzire ukadaulo watsopano wa fiber optical. Njira yolumikizirana ya 1.55 μm yosinthira njira imodzi yolumikizirana ndi fiber optic idakhazikitsidwa panthawiyi. Chingwechi chimagwiritsa ntchito njira yosinthira kunja (chipangizo cha electro-optical) ndi mlingo wotumizira mpaka 10 Gb / s ndi mtunda wotumizira mpaka 150 km popanda amplifier relay.
M'badwo wachinayi optical fiber communication system
1996-2009 ndi nthawi ya synchronous digito system Optical fiber transmission network. Njira yolumikizirana ndi optical fiber imayambitsa ma amplifiers optical kuti achepetse kufunikira kwa obwereza. The wavelength division multiplexing luso ntchito kuonjezera kuwala CHIKWANGWANI kufala mlingo (mpaka 10Tb / s) ndi kufala mtunda. Ikhoza kufika 160km.
Zindikirani: Mu 2002, ISO/IEC 11801 idalengeza movomerezeka kalasi yokhazikika ya fiber multimode, kuyika ma multimode fiber OM1, OM2 ndi OM3 CHIKWANGWANI. Mu 2009, TIA-492-AAAD idatanthauzira movomerezeka OM4 fiber.
M'badwo wachisanu wa optical fiber communication system
Njira yolumikizirana ndi ma fiber optical imayambitsa ukadaulo wa soliton wa optical, ndipo imagwiritsa ntchito mawonekedwe osagwirizana ndi ulusi kuti apange mafunde amphamvu kukana kubalalitsidwa pansi pa mawonekedwe oyambira. Panthawiyi, njira yolankhulirana ya fiber-optic imakulitsa bwino kutalika kwa kutalika kwa gawo la wavelength, ndipo 1530nm yoyambirira ya 1570 nm imafikira 1300 nm mpaka 1650 nm. Kuphatikiza apo, pakadali pano (2016) OM5 fiber imayambitsidwa mwalamulo.
