Intambo ye-fiber optic ibe yintsika yothungelwano lwanamhlanje, ixhasa i-intanethi ekhawulezayo, unxibelelwano, amaziko edatha, iziseko zophuhliso ze-5G, ukwenziwa kwezinto ngokuzenzekelayo kwimizi-mveliso, kunye nezixeko ezikrelekrele. Xa kuthelekiswa neentambo zekopolo zemveli, iintambo ze-fiber optic zibonelela nge-bandwidth ephezulu, ilahleko ephantsi yesiginali, umgama omde wothumelo, kunye nokumelana okungcono nokuphazamiseka kwe-electromagnetic.

Kwiinethiwekhi zonxibelelwano ezikhawulezayo zanamhlanje, intambo yefayibha iye yaba yenye yezona zinto zibalulekileyo zokudibanisa izixhobo ze-optical, izixhobo zenethiwekhi, kunye neenkqubo zokusasazwa kwefayibha. Ukusuka kumaziko edatha kunye neenethiwekhi zonxibelelwano ukuya kwi-FTTH (Fiber to the Home) deployments kunye neenkqubo zonxibelelwano lweshishini, iintambo ze-fiber patch zibonelela ngoqhagamshelo lwe-optical oluthembekileyo nolusebenza kakuhle.

Ngokusetyenziswa okukhulu kwe-FTTH Fiber eKhaya, amaziko edatha e-AI computing, i-5G fronthaul, i-indoor comprehensive wiring, i-FPV drone miniature communication kunye nokwakhiwa kohlaziyo lwangoku olubuthathaka kwihlabathi liphela, i-G.652D single-mode fiber yendabuko ihlushwa kukulahleka okukhulu kokugoba kunye nendawo encinci yocingo, nto leyo ethintela kakhulu ulwakhiwo lweenethiwekhi zonxibelelwano ze-optical ezikhawulezayo. Yenziwe yi-ITU-T, i-G.657 series bend-insensitive single-mode fiber yenzelwe ngokukodwa iikona ezijijekileyo, i-dense wiring kunye ne-micro-pipeline. Amanqanaba amathathu emveliso ephambili, i-G.657.A1 standard bend-resistant fiber, i-G.657.A2 ephuculweyo bend-resistant fiber kunye ne-G.657.B3 ultra-bend-insensitive fiber, isebenzisa iiprofayili ze-refractive index ezincediswa yi-trench-assisted refractive index, kwaye ibonisa umahluko olinganisiweyo kwi-minimum bending radius, i-mode field diameter kunye nokusebenza kwe-attenuation. Zigubungela iimfuno zemeko epheleleyo ukusuka kwi-wiring yasekhaya engabizi kakhulu ukuya kwi-ultra-compact special wiring.

Ukukhetha ekunene intambo ye-fiber optic yangaphandle ekhuselweyo Kubalulekile ekwakheni inethiwekhi ye-optical ethembekileyo, ehlala ixesha elide, nesebenza kakuhle. Nokuba usebenzisa i-fiber kwiinkonzo zonxibelelwano, i-FTTH, amaziko edatha, izakhiwo zoshishino, okanye iinkqubo zokhuseleko, ukukhetha intambo engalunganga kunokukhokelela ekugcinweni kweendleko eziphezulu, ukungasebenzi kwenethiwekhi, kunye nokungasebenzi kwentambo ngaphambi kwexesha.

A Ibhokisi yokuphelisa ifayibha yenye yezona zinto zibalulekileyo kwinethiwekhi zonxibelelwano lwe-optical zanamhlanje. Idlala indima ebalulekileyo ekukhuseleni, ekuhleleni, nasekusasazeni iintambo ze-fiber optic, ngakumbi kwi-FTTH (i-Fiber to the Home), i-FTTC, amaziko edatha, kunye neenkqubo ze-telecom backbone.

I-optical fiber yintambo ebhityileyo, eguquguqukayo, necacileyo eyenziwe ngeglasi okanye iplastiki ecocekileyo kakhulu ethumela idatha ngendlela yokukhanya. Ngokungafaniyo neentambo zekopolo zemveli, ezisebenzisa imiqondiso yombane, i-optical fiber isebenzisa ukukhanya, okuhlala kuveliswa zii-laser okanye ii-LED.

Abavelisi beentambo ze-fiber optic abaphambili kwihlabathi liphela ngo-2026 bakhokelwa yi Iqela lePrysmian (e-Itali), iCorning Inc. (e-USA), iFujikura Ltd. (eJapan), iSumitomo Electric (eJapan), kunye neYOFC (eTshayina)Ezi nkampani zilawula imveliso yefayibha kwihlabathi liphela ngenxa yobunkokeli bazo kwi iinkqubo zekhebula ezingaphantsi kwamanzi, iinethiwekhi ze-FTTH, iziseko zophuhliso ze-5G, kunye noqhagamshelo lweziko ledatha le-AI.

I-An intambo ye-fiber optic yangaphandle luhlobo lwentambo yefayibha ye-optical eyenzelwe ukufakwa kwiindawo zangaphandle. Yakhiwe ngeengqimba zokukhusela eziqinisiweyo ezikhusela iifayibha zeglasi ezithambileyo ngaphakathi ekonakaleni kwendalo kunye noxinzelelo lomzimba.

Njengoko utshintsho lwedijithali lukhawuleza kumashishini onke, amaziko edatha afumana ukukhula okungazange kwenzeke ngaphambili kumthamo wezithuthi, umthwalo womsebenzi wekhompyutha elifini, usetyenziso lwe-artificial intelligence (AI), kunye neemfuno zothungelwano olukhawulezayo. Iziseko zophuhliso zekhebula zemveli ziya zichatshazelwa ngakumbi yimfuno ye-bandwidth ephezulu, i-latency ephantsi, kunye noxinano olukhulu lwezibuko.

I-Optical fiber ifezekisa ukuhanjiswa kwesignali ngokukhanya kwangaphakathi okupheleleyo kwe-infrared ngaphakathi kwe-silica core. Ithintelwe kukulahlekelwa kokufunxwa kwe-silica ngaphakathi, ukusasazeka kweRayleigh, ukufunxwa kwe-infrared kunye nokuncitshiswa kwe-hydroxyl water peak, ii-wavebands ezintandathu zorhwebo zisemgangathweni kushishino lonxibelelwano lwe-optical lwehlabathi: 850 nm, 1310 nm, 1383 nm, 1490 nm, 1550 nm kunye ne-1625 nm. Ezi wavelengths zigubungela i-LAN emfutshane, inethiwekhi ye-metropolitan, i-long-haul backbone, ukufikelela kwi-PON fiber, i-optical amplification kunye ne-optical fiber testing scenarios. Kukho umahluko ohlukileyo kwi-attenuation coefficient, i-chromatic dispersion, umgama ophezulu wokudluliselwa, ii-optoelectronic components matching kunye nokukhetha i-fiber phakathi kwee-wavebands ezahlukeneyo, ezisebenza njengeekhrayitheriya ezisisiseko zokukhetha iinkcukacha ze-fiber, uyilo lobunjineli kunye ne-optical component R&D. Eli phepha linamacandelo amathathu angundoqo: iimpawu ze-optical ezineenkcukacha zee-wavebands ezintandathu, uthelekiso oluthe tye lweenkcukacha zobugcisa ze-core fiber, kunye ne-fibre matching kunye nohlu lwesicelo esisebenzayo kwi-wavelength nganye.
