Zvichienderana neruzivo rutsva rwuripo kubva muna Kubvumbi 2026, kurongwa kwemhando yefiber optic inogadzirwa munyika muChina kunonyanya kutariswa kuburikidza nekuongorora kwakazara muzvikamu zvakaita sesimba rehunyanzvi, mugove wemusika, kuzvitonga kwecheni yekugovera, budiriro muhunyanzvi hwemiganhu, uye ongororo dzeindasitiri dzine mvumo. Aya ndiwo makambani efiber optic anozivikanwa parizvino uye chinzvimbo chavo chemhando:

China Domestic Fiber Optic First Tier (Chain Yeindasitiri Yakazara + Hutungamiriri hweTekinoroji):

1/ YOFC (Yangtze Optical Fibre neCable) — YOFC Fiber
Yakaiswa panhamba 1 pasi rose mumusika kwemakore mapfumbamwe akatevedzana; ine mukurumbira weMwero wekuzvigutsa we100% wezvishandiso zve optical preformsuye akakwanisa kugadzira zvinhu zvitatu zvikuru: PCVD, OVD, uye VAD.
Inotungamira muzvigadzirwa zvepamusoro-soro: Fiber yayo yeG.654.E yakaderera zvakanyanya uye fiber ine hollow-core (ine attenuation yakaderera se0.05 dB/km) yatotanga kugadzirwa.
Vatengi vayo vanosvika nyika dzinopfuura zana pasi rose, uye mari inowanikwa kunze kwenyika inodarika 40% yemari yose inowanikwa.

2/ HTGD (Hengtong Optic-Electric) — Hengtong Fiber
Mutungamiriri wepaviri mu fiber optics ne submarine cables**;inochengetedza chiyero chekuzvikwanira che preform chinodarika 90%uye inoshandisa "Lighthouse Factory" yekutanga muindasitiri yekutaurirana kwemaziso pasi rose.
Yakatanga tekinoroji yekugadzira green preform munyika**; matekinoroji ayo efiber ane macore akawanda, mafekitori mashoma, uye mahollow-core ari padanho repamusoro-soro pasi rose.
Ine musika wepasi rose weinopfuura 20% mumakambani engarava dzemugungwa uye yakaita mapurojekiti makuru ekukurukurirana kwegungwa anopfuura zana.

3/ ZTT (Zhongtian Technology) — ZTT Fiber
Mutungamiriri wepamba mune fiber dzakasarudzika**, ane mugove wemusika we30%–40%; akabudirira kuderedza kuderera kwefibers dze anti-resonant hollow-core neanenge 40%.
Yakagadzira hurongwa hwakazara, hwekupedzisira kusvika kumagumo hweindasitiri hunosanganisira "preforms—fibers—cables—optical modules—midziyo."
Ndakabatanidzwa zvakanyanya mukupa tambo dzisinganyanyi kusimba dze "Eastern Data, Western Computing" uye nzvimbo dzedata dzeAI.

4/ FiberHome (FiberHome Telecommunication Technologies) — FiberHome Fiber
Bhizinesi re "National Team" riri pasi pehurumende yepakati (rimwe remakambani ari pasi peChina Information Communication Technologies Group);inochengetedza chiyero chekuzvikwanira che preform chinosvika 85%.
Kufambira mberi nekukurumidza mukusimudzira tekinoroji ye fiber isina chinhu, nechinangwa chekuisa rekodhi yepasi rose panosvika gore ra2025 ine simba re fiber imwe chete rinodarika 100 Tb/s mu C+L bands.

Inochengetedza hukama hwakasimba nemakambani matatu makuru emafoni ekuChina pamwe nemapurojekiti makuru enyika e "New Infrastructure".
Makambani mana aya anonyanya kutaurwa muindasitiri iyi se "Big Four of Fiber Optics," uye pamwe chete anogara pa **tier yekutanga yepasi rose** maererano nemhando, tekinoroji, uye kugona kugadzira.

Mamwe Makambani Emhando Yepamusoro eFiber Optic eDzimba (Vatungamiriri muZvikamu zveNiche):

Kubatana kweTongding: Mutengesi mukuru mukutenga zvinhu zvemakambani, ane mugove wakakura pamusika mumakambani emagetsi akasarudzika (akapihwa mugove we18.85% muChina Mobile's 2026 procurement tender).

Yongding Shares: Ine dhizaini yakazara, ine kukosha kwakazara munzvimbo yese yeRwizi rweYangtze mudunhu reDelta, ichishandisa kubatana pakati pefiber optics nema optical modules.

Tefa Information (CDGI): Mupi mukuru wezvigadzirwa zvesimba remakombiyuta muSouth China, ane mugove mukuru mumusika weMPO connectors dzeAI data centers.

Boka reFutong: Chimwe chezvinhu zvakakosha zvine basa rekugadzira mitemo yehunyanzvi hwekugadzira fiber preforms.
