"Ukuba ufuna ukuba zizityebi, yakha iindlela kuqala", uphuhliso olukhawulezayo lwe-3G / 4G kunye ne-FTTH yaseTshayina ayinakuhlukaniswa kwi-paving yokuqala yeziseko ze-fiber optical, eziye zaphumelela ukukhula ngokukhawuleza kwe-China ye-optical fiber kunye nabavelisi beentambo.Abavelisi behlabathi be-TOP10 abahlanu eTshayina, abancedisana kwaye bakhule kunye.Kwixesha le-5G, kunye nokuthengiswa ngokusemthethweni kwe-5G, imfuno ye-fiber optical kunye nekhebula iya kuqhubeka ikhula ngokukhawuleza, kwaye iqhubeke nokuncedisa ukuchuma kweshishini lonxibelelwano lwe-optical.Ukwandiswa komthamo wangaphambili kunokubonwa njengoyilo lwangaphambili ngaphambi kokuba i-5G ifike.
U-Wei Leping waxela kwangaphambili ukuba ngokwe-3.5G inethiwekhi ezimeleyo, isikhululo se-macro sangaphandle kufuneka sibe ubuncinane kabini kwi-4G, kwaye ukuba i-3.5G + 1.8G / 2.1G inethiwekhi yokubambisana ilandelwa, isikhululo se-macro sangaphandle kufuneka sibe ubuncinane. I-1.2 amaxesha e-4G. Ngexesha elifanayo, ukugubungela kwangaphakathi kuxhomekeke kumashumi ezigidi zezikhululo ezincinci.Ingabonwa ukuba inani elikhulu le-fiber optical interconnections lisafuneka phakathi kwezikhululo ezahlukeneyo ze-5G.
Nangona kunjalo, ngexesha "2019 Global Optical Fiber kunye neNkomfa yeCable", uGao Junshi, umlawuli weCable Institute yeChina Mobile Communication Group Design Institute, wathi xa kuthelekiswa neFTTx, ixesha le-5G kunzima ukuphinda kwakhiwe ubuqaqawuli obufanayo bentambo ye-optical cable. imarike.Ngaphantsi kwemvelaphi ye-saturation eyisiseko ye-FTTx e-China, imfuno epheleleyo ye-5G i-fiber optical kunye nekhebula lincinci kwaye lizinzile, kwaye imfuno yonke ye-optical cable kwixesha le-5G iya kungena kwixesha elizinzile.
Ngelo xesha, elinye ithuba lophuhliso kwixesha le-5G linokuba kwinqanaba le-trunk yesizwe. I-5G yorhwebo, i-computing yefu ephezulu, idatha enkulu, i-intanethi yezinto, i-media media kunye nezinye iteknoloji ezikhulayo kunye neenkonzo ziyaqhubeka nokuvela, uxinzelelo lwe-bandwidth yenethiwekhi. iyanda, abaqhubi babeka phambili iimfuno eziphezulu zomthamo wefayibha enye, kodwa baphinde babeke phambili iimfuno zothumelo lwe-ultra-high-speed transmission kwimigca yomgama omde.Iintambo ezisibhozo ezithe tyaba zaseTshayina nezisibhozo ezithe nkqo zetrank zakhiwe ngaphezulu kweminyaka engama-20, kwaye ibhetshi yokuqala yemigca yentambo ye-trunk optical ifikelele kwinqanaba lokugqibela lobomi boyilo.Ukuze kuhlangatyezwane neemfuno zoshishino zexesha le-5G, inethiwekhi yomqolo iya kungena kwakhona kumjikelezo wokutshintshwa kunye nokwakhiwa kwiminyaka embalwa ezayo.
U-Wei Leping uye wabonisa ukuba kwixesha le-5G, i-backbone high-capacity routing iya kujika kwi-low-loss G.654.E fibers optical fibers.Ngo-2019, i-China Telecom kunye ne-China Unicom ngokulandelelana zenze ingqokelela ye-cable ye-G.654.E, mhlawumbi ukususela ngo-2020, ukuqokelelwa kwentambo ye-trunk kunokuba rhoqo.
Ukongeza, kwathethwa ngokubanzi kwishishini ngoDisemba 2019 ukuba emva kokufumana ilayisenisi yentengiso ye-5G, i-China Radio kunye neTelevishini iya kusebenzisana ngokunzulu neGridi yeSizwe ukwakha izikhululo ezisisiseko ze-113,0005G kwi-2020. Umgca wombuso weGridi ubukhulu becala yi-OPGW, inani le-fiber optical cores lincinci, iinkqubo ezithwala ngakumbi, izinga eliphezulu lokusetyenziswa kwezixhobo, kunye namanye amacandelo ezibonelelo zentambo ye-optical ine-bottlenecks.Izitishi ezitsha ze-113,0005G ziya kuvelisa imfuno eqinileyo yeentambo ze-optical.
