Thumela uPhando ukuze ukhuphele iPhepha leDatha yeMveliso

I-FTTH, i-FTTB, i-MDU intambo yangaphakathi yeyunithi ezininzi, iintambo zedatha ezikomponenti kunye nokufakwa kwe-microduct kubeke phambili iimfuno ezingqongqo zokusebenza kwe-fiber bend. I-fiber ye-G.652.D yesiqhelo iya kuvelisa ilahleko ebonakalayo ye-macrobending xa i-radius bend incinci kakhulu, okubangela ukuncitshiswa okukhulu kwe-optical, inkonzo ye-PON engazinzile, ukuphuma okungapheliyo kunye nokuqhekeka kwe-fiber kwindawo. I-ITU-T ikhuphe umgangatho we-G.657 ukusombulula le ngongoma yentlungu, ichaza ii-fiber ezimbini eziphambili ezihambelana ne-backward bend insensitivity.

Ukukhetha ifayibha yemowudi enye engalunganga kukhokelela ekulahlekelweni kakhulu kwe-optical, ukungaphumeleli kokwamkelwa kweprojekthi, ukuphinda kulungiswe ngokungeyomfuneko, kunye nokuchithwa kwemali-mali. Kangangamashumi eminyaka, G.652D kwaye G.657A2 Ziye zalawula iiprojekthi ze-fiber optic zehlabathi, ukusuka kwiinethiwekhi ze-telecom backbone ezikude, ii-metro fiber links, i-data center cables ukuya kwi-FTTH fiber-to-the-home deployment. Abaphathi abaninzi bokuthenga, iinjineli zasemaphandleni kunye nabayili benethiwekhi bahlala bejongene nokudideka okufanayo: Sifanele siyisebenzise nini i-G.652D fiber? Zeziphi iimeko ezifuna i-G.657A2 bend-insensitive fiber? Ngaba ezi ntlobo zimbini ze-fiber zinokudityaniswa kunye kwiinethiwekhi ze-hybrid?

I-Duct kunye ne-Direct-Bried zibhekisa kuzo iindlela zokufaka indlelaU-Armored uchaza uyilo lwesakhiwo sentambo. Ezi ndidi ziyadibana, kwaye azifani. Ungafaka intambo exhonyiweyo ngaphakathi kwimibhobho; iindlela ezingcwatywe ngqo phantse zisoloko zifuna ukwakhiwa okuxhonyiweyo. Ukungawuqondi kakuhle lo mgaqo usisiseko kukhokelela ekuqhekekeni kwentambo ngaphambi kwexesha, ukutshintshwa okungalindelekanga, ukuhlolwa okungamkelekanga, kunye nemingcipheko yokuthembeka kwenethiwekhi yeminyaka emininzi.

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.
