OPGW ndi chingwe chogwira ntchito pawiri chomwe chimagwira ntchito ya waya pansi komanso chimapereka chigamba chotumizira mawu, makanema kapena ma siginali a data. Ulusiwo umatetezedwa kuzinthu zachilengedwe (mphezi, mtunda waufupi, kutsitsa) kuti zitsimikizire kudalirika komanso moyo wautali. Chingwecho chinapangidwa kuti chiziyika pamizere yotumizira ndi kugawa kuti inyamule mauthenga a mawu, deta ndi mavidiyo, makamaka muzitsulo zowunikira ma waveform, njira yowonera pamzere woyesera pamwamba, dongosolo la chidziwitso cha deta, dongosolo la chitetezo cha mzere wamagetsi, makina opangira magetsi. , ndi kuyang'anira kagawo kakang'ono kosayendetsedwa.
GL imayang'ana kwambiri pakukula ndi kupanga chingwe cha FO kwa zaka 16 ndipo OPGW ndi imodzi mwazinthu zathu zazikulu, zogulitsa zathu zimatumizidwa kumayiko oposa 160. Pali ma decigni 4 wamba a OPGW fiber optic zingwe zoperekedwa kuchokera ku GL.
OPGW Mapangidwe Odziwika a Central Stainless Steel Loose chube, chubu chapakati chachitsulo chosapanga dzimbiri chimazunguliridwa ndi zigawo ziwiri kapena ziwiri za mawaya azitsulo za aluminiyamu (ACS) kapena kusakaniza mawaya a ACS ndi mawaya a aluminiyamu aloyi. ndi zingwe zomwe zimagwiritsidwa ntchito kwambiri, kapangidwe kake kamakhala kogwirizana ndi zomwe zimafunikira pamagetsi amagetsi.
OPGW Mapangidwe Odziwika a Stranded Stainless Steel Tube, The Stranded Optical Ground Wire (OPGW) amangiriridwa ndi zigawo ziwiri kapena zitatu za mawaya achitsulo opangidwa ndi aluminiyamu (ACS) kapena kusakaniza mawaya a ACS ndi mawaya a aluminiyamu aloyi, kapangidwe kake kamakhala kogwirizana kwambiri kufunikira kwa chingwe chamagetsi.
Al-yokutidwa ndi Stainless Steel Tube OPGW, Chubu chachitsulo chapakati cha AL-chokutidwa ndi chozunguliridwa ndi zigawo ziwiri kapena ziwiri za mawaya azitsulo za aluminiyamu (ACS) kapena mawaya osakanikirana a ACS ndi mawaya a aluminiyamu. ya AL, kuti mufikire kulakwitsa kwaposachedwa komanso kukana kwa mphezi. Gwiritsani ntchito chingwe chotumizira chomwe chimafuna m'mimba mwake pang'ono ndi vuto lalikulu lapano.
PBT Aluminium Tube OPGW, The PBT Loose Tube Optical Ground Wire (OPGW) yazunguliridwa ndi zigawo ziwiri kapena ziwiri za mawaya azitsulo za aluminiyamu (ACS) kapena kusakaniza mawaya a ACS ndi mawaya a aluminiyamu aloyi. Good anti-corrosion performance.Material and structure are uniform, good resistance to vibration kutopa.
