M'zaka zaposachedwa, pomwe gulu lazidziwitso zapamwamba likukulirakulira mwachangu, zida zolumikizirana patelefoni zakhala zikumanga mwachangu ndi njira zosiyanasiyana monga kuyika maliro mwachindunji ndi kuwomba.
Chingwe chowomberedwa ndi mpweya cha Optical FiberNdi kakulidwe kakang'ono, kulemera kopepuka, kowonjezera pamwamba pa m'chimake fiber unit opangidwa kuti aziwombera mu mitolo yaying'ono yamachubu ndi kutuluka kwa mpweya. Machubu otayirira amapangidwa ndi mapulasitiki apamwamba a modulus (PBT) ndipo amadzazidwa ndi gel osamva madzi. Machubu otayirira amazunguliridwa mozungulira membala omwe si achitsulo chapakati (FRP). Polyethylene (PE) imatulutsidwa ngati sheath yakunja. Ndiwosavuta kukhazikitsa optical fiber network communications infrastructure yomwe imapereka yankho lapamwamba kwambiri la fiber lomwe likupezeka masiku ano.
Lero, Tiyeni tikhale ndi phunziro pa Air-blown Microduct Cable.
Kapangidwe:
Lose chubu: PP kapena zinthu zina zomwe zilipo
Zida zotsekera madzi pachubu lotayirira: ulusi wotsekereza madzi ulipo
Zida zotsekera madzi pachimake cha chingwe: tepi yotchinga madzi ikupezeka
Chovala chakunja: Nayiloni ilipo
Mbali:
Voliyumu yaying'ono, kulemera kopepuka, kachulukidwe kakang'ono ka fiber, sungani zida zama duct
Kugundana kochepa, kuwulutsa kwamphamvu kwa mpweya
Kusokoneza kwa dielectric, anti-mphezi, anti-electromagnetic
Kukonza kosavuta, kukulitsa kosavuta
Onse gawo madzi kutsekereza
Kutumiza kwabwino, makina komanso magwiridwe antchito achilengedwe
Moyo wopitilira zaka 30
Ntchito:
Kuyika kwa mpweya
Netiweki yam'mbuyo ndi netiweki ya metro
Pezani netiweki
Deta yaukadaulo:
Min. pindani utali wozungulira: unsembe 20D, ntchito 10D
Kutentha osiyanasiyana: yosungirako -40°+70 ℃, unsembe -30～+70 ℃, ntchito -20～+70℃
