Lus Cim: Lwm cov qauv thiab cov suav fiber ntau kuj muaj raws li cov neeg siv khoom xav tau.
Ntoo nruas uas tsis yog rov qab.
Ob qhov kawg ntawm fiber ntau optic cables tau ruaj khov rau lub nruas thiab kaw nrog lub hau shrinkable los tiv thaiv kev nkag mus ntawm cov dej noo.
• Txhua qhov ntev ntawm cable yuav tsum tau reeled ntawm Fumigated Ntoo Nruas
• Npog los ntawm daim ntawv yas tsis zoo
• Muab cov battens ntoo muaj zog
• Yam tsawg kawg 1 m ntawm sab hauv kawg ntawm cable yuav raug tshwj tseg rau kev sim.
• Nruas ntev: Txheem nruas ntev yog 3,000m ± 2%;
Tus naj npawb ntawm cov kab ntev yuav tsum tau muab cim rau ntawm sab nraud ntawm lub cable ntawm lub caij nyoog ntawm 1meter ± 1%.
Cov ntaub ntawv hauv qab no yuav tsum tau muab cim rau ntawm sab nraud ntawm lub cable ntawm ib ntus txog li 1 meter.

Lus Cim: Cov cables tau ntim rau hauv thawv, coiled ntawm Bakelite & steel nruas. Thaum lub sij hawm kev thauj mus los, cov cuab yeej zoo yuav tsum tau siv kom tsis txhob ua kom puas lub pob thiab ua kom yooj yim. Cables yuav tsum muaj kev tiv thaiv los ntawm ya raws, khaws cia kom deb ntawm kub thiab hluav taws kub, tiv thaiv los ntawm kev khoov thiab crushing, tiv thaiv los ntawm txhua yam kev nyuaj siab thiab kev puas tsuaj.
Nyob rau xyoo 2004, GL FIBER tau tsim lub Hoobkas los tsim cov khoom siv kho qhov muag, feem ntau tsim cov kab hluav taws xob, sab nraum zoov kho qhov muag cable, thiab lwm yam.
GL Fiber tam sim no muaj 18 txheej ntawm cov khoom siv xim, 10 txheej txheej txheej txheej txheej txheej txheej, 15 txheej ntawm SZ txheej twisting equipments, 16 txheej ntawm sheathing equipments, 8 txheej ntawm FTTH poob cable ntau lawm, 20 txheej ntawm OPGW optical cable equipments, thiab 1 paralleling khoom Thiab ntau lwm yam khoom pab khoom siv. Tam sim no, txhua xyoo muaj peev xwm ntawm optical cables ncav cuag 12 lab core-km (qhov nruab nrab txhua hnub muaj peev xwm ntawm 45,000 core km thiab hom cables tuaj yeem ncav cuag 1,500 km). Peb cov chaw tsim khoom tuaj yeem tsim ntau hom kab hluav taws xob sab hauv tsev thiab sab nraum zoov (xws li ADSS, GYFTY, GYTS, GYTA, GYFTC8Y, cua tshuab micro-cable, thiab lwm yam). lub peev xwm tsim khoom txhua hnub ntawm cov kab hluav taws xob ntau tuaj yeem ncav cuag 1500KM / hnub, lub peev xwm tsim tawm txhua hnub ntawm kev poob cable tuaj yeem ncav cuag max. 1200km / hnub, thiab txhua hnub muaj peev xwm ntawm OPGW tuaj yeem ncav cuag 200KM / hnub.
