Thumela Uphenyo ukuze Ulande Ishidi Ledatha Lomkhiqizo

Izintambo zangaphakathi ze-FTTH, FTTB, MDU, izintambo zangaphakathi zeyunithi eziningi, izintambo zedatha ezihlanganisiwe kanye nokufakwa kwe-microduct kubeke phambili izidingo eziqinile zokusebenza kokugoba kwefayibha. Ifayibha ye-single mode ye-G.652.D yendabuko izokhiqiza ukulahlekelwa okusobala kokugoba kwe-macro lapho i-radius yokugoba incane kakhulu, okuholela ekunciphiseni okukhulu kwe-optical, isevisi ye-PON engazinzile, ukuyeka ngezikhathi ezithile kanye nokuqhekeka kwefayibha endaweni. I-ITU T ikhiphe indinganiso ye-G.657 ukuxazulula leli phuzu lobuhlungu, ichaza ifayibha ezimbili ezijwayelekile ezihambisana nokugoba okungenakuzwela emuva.

Ukukhetha i-fiber yemodi eyodwa engalungile kuholela ekulahlekelweni okukhulu kokukhanya, ukwehluleka kokwamukelwa kwephrojekthi, ukulungiswa kabusha okungadingekile, kanye nokutshalwa kwezimali okuchithwayo. Sekungamashumi eminyaka, G.652D futhi G.657A2 Kuye kwabusa amaphrojekthi e-fiber optic omhlaba wonke, kusukela kumanethiwekhi e-telecom backbone akude, izixhumanisi ze-metro fiber, izintambo zedatha kuya ekufakweni kwe-FTTH fiber-to-the-home. Abaphathi abaningi bokuthengwa kwempahla, onjiniyela basensimini kanye nabaklami benethiwekhi bahlala bebhekene nokudideka okufanayo: Kufanele sisebenzise nini i-G.652D fiber? Yiziphi izimo ezidinga i-G.657A2 bend-insensitive fiber? Ingabe lezi zinhlobo ezimbili ze-fiber zingahlanganiswa ndawonye kumanethiwekhi e-hybrid?

Ipayipi kanye ne-Direct-Bried kubhekisela kuyo izindlela zokufaka umzilaI-Armored ichaza ukwakheka kwesakhiwo sekhebula. Lezi zigaba ziyahlangana, futhi azihlukani. Ungafaka ikhebula elivikelwe ngaphakathi kwemigudu; imizila egqitshwe ngqo cishe njalo idinga ukwakhiwa okuvikelwe. Ukungaqondi kahle lesi simiso esiyisisekelo kuholela ekuqhekekeni kwekhebula ngaphambi kwesikhathi, ukulungiswa kabusha okungalindelekile, ukuhlolwa okwenqatshiwe, kanye nezingozi zokuthembeka kwenethiwekhi zeminyaka eminingi.

Ikhebula le-fibre optic seliyinsika yamanethiwekhi okuxhumana anamuhla, lisekela i-inthanethi esheshayo, ezokuxhumana, izikhungo zedatha, ingqalasizinda ye-5G, ukuzenzekela kwezimboni, kanye namadolobha ahlakaniphile. Uma kuqhathaniswa nezintambo zethusi zendabuko, izintambo ze-fibre optic zinikeza i-bandwidth ephezulu, ukulahleka kwesignali okuphansi, amabanga amade okudlulisela, kanye nokumelana okungcono nokuphazamiseka kwe-electromagnetic.

Kumanethiwekhi okuxhumana asheshayo anamuhla, intambo yesichibi sefayibha isibe ngenye yezingxenye ezibaluleke kakhulu zokuxhumanisa amadivayisi e-optical, imishini yenethiwekhi, kanye nezinhlelo zokusabalalisa i-fiber. Kusukela ezikhungweni zedatha kanye namanethiwekhi ezokuxhumana kuya ekusetshenzisweni kwe-FTTH (Fiber to the Home) kanye nezinhlelo zokuxhumana zebhizinisi, izintambo ze-fiber patch zinikeza ukuxhumana kwe-optical okuthembekile nokusebenza kahle.

Ngokusetshenziswa okukhulu kwe-FTTH Fiber ekhaya, izikhungo zedatha ze-AI computing, i-5G fronthaul, izintambo ezibanzi zangaphakathi, ukuxhumana okuncane kwe-FPV drone kanye nokwakhiwa kokuvuselelwa kwamanje okubuthakathaka emhlabeni wonke, intambo yendabuko ye-G.652D single-mode ihlushwa ukulahlekelwa okukhulu kokugoba kanye nesikhala esilinganiselwe socingo, okuvimbela kakhulu ukwakheka kwamanethiwekhi okuxhumana we-optical asheshayo. Yakhiwe yi-ITU-T, intambo ye-single-mode engazweli uchungechunge lwe-G.657 series bend-insensitive ithuthukiswe ngokukhethekile kumakhona amancane okujika, izintambo ezixinene kanye nezimo zepayipi elincane. Amabanga amathathu omkhiqizo ojwayelekile, intambo ejwayelekile engazweli ukugoba ye-G.657.A1, intambo ethuthukisiwe engazweli ukugoba ye-G.657.A2 kanye nentambo engazweli ukugoba ye-G.657.B3 ultra-bend, isebenzisa amaphrofayili enkomba yokubuyisa asekelwe emseleni ahlukene, futhi aveza umehluko olinganisiwe ku-radius encane yokugoba, ububanzi bensimu yemodi kanye nokusebenza kokunciphisa. Zihlanganisa izidingo zesimo esigcwele kusukela kuzintambo zasekhaya ezingabizi kakhulu kuya kuzintambo ezikhethekile eziqinile kakhulu.

Ukukhetha kwesokudla ikhebula le-fiber optic langaphandle elivikelwe kubalulekile ekwakheni inethiwekhi ye-optical ethembekile, ehlala isikhathi eside, futhi esebenza kahle kakhulu. Kungakhathaliseki ukuthi usebenzisa i-fiber yezokuxhumana, i-FTTH, izikhungo zedatha, izikhungo zezimboni, noma izinhlelo zokuphepha, ukukhetha ikhebula elingalungile kungaholela ekunakekelweni okubizayo, ukungasebenzi kwenethiwekhi, kanye nokwehluleka kwekhebula ngaphambi kwesikhathi.
