Shiinaha ugu sarreeya 3 alaab-qeybiyaha fiilada fiber optic-ga ee hawada lagu afuufay, GL wuxuu leeyahay waayo-aragnimo sannado ka badan 17, Maanta, waxaan soo bandhigi doonaa fiilada fiber optic-ga gaarka ah ee SFU (Cutubka Fiber-ka siman ).
Cutubka Fiber Jilicsan (SFU) waxa uu ka kooban yahay xidhmo radius qalloocan oo hooseeya, aan lahayn waterpeak G.657.A1 fibre, oo ay ku duuban yihiin lakabka qalalan ee acrylate waxaana lagu ilaaliyaa gal-dabeed, oo wax yar ka lumay polyetylen, si loogu codsado shabakada gelitaanka.Rakibaadda: ku afuufo microducts ee 3.5mm.ama 4.0mm.(dhexroorka gudaha).

5,Xidhmada Iyo Durbaanka
Fiilooyinku waxay ku jiraan kartoon, oo lagu duuduubay Bakelite & durbaan alwaax ah oo Fumigated ah.Inta lagu jiro gaadiidka, agabka saxda ah waa in la isticmaalo si looga fogaado waxyeelada xirmada iyo in si sahlan loo maareeyo.Fiilooyinka waa in laga ilaaliyaa qoyaanka;laga fogeeyay heerkulka sare iyo dhimbilaha dabka;laga ilaaliyo foorarsiga badan iyo burburinta;laga ilaaliyo cadaadiska farsamada iyo dhaawaca.
Dhererka xirmada: 2000-5000m/reel.
