"Inā makemake ʻoe e waiwai, e kūkulu mua i nā alanui", ʻaʻole hiki ke hoʻokaʻawale ʻia ka hoʻomohala wikiwiki ʻana o ka 3G / 4G a me FTTH o Kina mai ka paving mua ʻana o ka ʻōnaehana fiber optical, kahi i hoʻokō ai i ka ulu wikiwiki ʻana o ka fiber optical a me nā mea hana kelepona o Kina. ʻElima mau mea hana TOP10 honua ma Kina, e hoʻopiha i kekahi i kekahi a ulu pū. I ka wā 5G, me ka hoʻolaha kūʻai ʻana o 5G, e hoʻomau mau ka noi no ka fiber optical a me ke kaula, a hoʻomau i ke kōkua ʻana i ka pōmaikaʻi o ka ʻoihana kamaʻilio optical. Hiki ke ʻike ʻia ka hoʻonui mua ʻana ma ke ʻano he hoʻolālā mua ma mua o ka hiki ʻana mai o 5G.
Ua wānana mua ʻo Wei Leping e like me ka pūnaewele kūʻokoʻa 3.5G, ʻoi aku ka liʻiliʻi o ke kikowaena macro waho ma ka liʻiliʻi ʻelua o ka 4G, a inā e hahai ʻia ka 3.5G+1.8G/2.1G pūnaewele hui pū ʻana, pono ke kikowaena macro waho ma ka liʻiliʻi. 1.2 mau manawa o 4G. Ma ka manawa like, pili ka uhi o loko i nā ʻumi miliona o nā kahua kahua liʻiliʻi. Hiki ke ʻike ʻia ka nui o nā pilina fiber optical e pono ai ma waena o nā kikowaena kumu 5G.
Eia nō naʻe, i ka wā o ka "2019 Global Optical Fiber and Cable Conference", ʻo Gao Junshi, ka luna o ka Cable Institute of China Mobile Communication Group Design Institute, i ʻōlelo ʻia i ka hoʻohālikelike ʻia me FTTx, paʻakikī ka wā 5G e kūkulu hou i ka nani like o ke kelepona optical. makeke. Ma lalo o ke kumu o ka saturation kumu o ka uhi FTTx ma Kina, ʻo ka noi holoʻokoʻa no ka 5G optical fiber a me ke kaula he liʻiliʻi a paʻa, a ʻo ka noi holoʻokoʻa no ke kelepona optical i ka wā 5G e komo i kahi manawa paʻa.
Ma ka manawa like, aia kekahi manawa hoʻomohala hou i ka wā 5G ma ka pae ʻāina. ke hoʻonui nei, hoʻopuka nā mea hana i nā koi kiʻekiʻe no ka mana fiber hoʻokahi, akā hāʻawi pū kekahi i nā koi o ka hoʻouna ʻana i ka ultra-high-speed no nā laina kumu lōʻihi. Ua kūkulu ʻia ka ʻewalu ākea a me ʻewalu kuʻekuʻe o Kina no nā makahiki ʻoi aku ma mua o 20, a ʻo ka pūʻulu mua loa o nā laina uwea ʻōpala i hiki i ka pae hope o ke ola hoʻolālā. I mea e hoʻokō ai i nā pono ʻoihana o ka wā 5G, e komo pū ka ʻupena kuamoʻo i ka pōʻai hou a me ke kūkulu ʻana i nā makahiki e hiki mai ana.
Ua kuhikuhi ʻo Wei Leping i ke au o 5G, e huli ka iwi kuamoʻo kiʻekiʻe o ke ala ala i nā fibers optical G.654.E. I ka makahiki 2019, ua hoʻokō ʻo China Telecom a me China Unicom i ka hōʻiliʻili kelepona G.654.E, malia paha mai 2020, ʻoi aku ka nui o ka hōʻiliʻili ʻana o ke kaula.
Eia kekahi, ua hoʻolaha nui ʻia i ka ʻoihana ma Dekemaba 2019 ma hope o ka loaʻa ʻana o ka laikini kalepa 5G, e hui pū ʻo China Radio a me Television me State Grid e kūkulu i nā kahua kahua 113,0005G ma 2020. ʻO ka laina o ka mokuʻāina ʻo Grid ʻo OPGW ka nui, liʻiliʻi ka helu o nā cores optical fiber, ʻoi aku ka nui o nā ʻōnaehana, kiʻekiʻe o ka hoʻohana ʻana i nā kumuwaiwai, a ʻo kekahi mau ʻāpana o nā kumuwaiwai optical cable he bottlenecks. E hoʻoulu ʻia nā kahua kahua 113,0005G hou i ke koi ikaika no nā uwea optical.
