Iyo inodonha tambo inonziwo dish-shaped drop drop cable (yemukati wiring), inova yekuisa optical communication unit (optical fiber) pakati, uye nekuisa mbiri dzakafanana dzisiri-metallic reinforcement nhengo (FRP) kana simbi yekusimbisa nhengo. kumativi ose.Pakupedzisira, yakawedzera dema kana chena , grey polyvinyl chloride (PVC) kana yakaderera-utsi halogen-isina zvinhu (LSZH, yakaderera chiutsi, halogen-isina, murazvo wemoto) sheathed.Iyo yekunze inodonha tambo ine inozvitsigira yakaturika waya muchimiro-8 chimiro.
Iyo yekudonha tambo inowanzo patsanurwa kuita 1 core, 2 cores uye 4 cores single-mode fiber optic tambo.Kazhinji, musimboti mumwechete unoshandiswa kutapurirana data remumba, uye maviri cores anoshandiswa redhiyo, terevhizheni, tambo TV uye Broadband.
donhwe tambo optical fibers kazhinji inosanganisira G657A2 optical fibers, G657A1 optical fibers, uye G652D optical fibers.Kune marudzi maviri ekusimbisa kwepakati, simbi yekusimbisa uye isiri-simbi FRP reinforcements.Masimbi ekusimbisa anosanganisira ① phosphating simbi waya ② copper plated simbi waya ③ galvanized simbi waya ④ glued simbi waya (kusanganisira phosphated simbi waya uye galvanized simbi waya nenamo).Zvisiri-metallic reinforcements zvinosanganisira ①GFRP②KFRP③QFRP.
Iyo sheath yetambo yekudonha kazhinji ichena, dema, uye grey.Ichena inowanzo shandiswa mumba, uye nhema inoshandiswa kunze, inodzivirira UV uye inodzivirira kunaya.Iyo sheath zvinhu inosanganisira PVC polyvinyl chloride uye LSZH yakaderera-utsi halogen-isina murazvo unodzosera sheath zvinhu.Kazhinji, vagadziri vanokamura LSZH yakaderera-utsi halogen-isina murazvo retardant zviyero mumhando nhatu: isiri-murazvo inodzoreredza, imwechete yakatwasuka inobvira moto inodzoreredza, uye bundle flame retardant.
Outdoor optical tambo yekumisa mitsetse inogona kazhinji kuzvitsigira 30-50 metres.Phosphating simbi waya inotora 0.8-1.0MM, galvanized simbi waya, glued simbi waya.
Zvimiro zvekudonhedza tambo: yakakosha beng-resistant optical fiber, inopa yakakura bandwidth uye inosimudzira network kutapurirana kuita;maviri akafanana FRP kana simbi inosimbisa inoita kuti tambo yemaziso ive yakanaka yekumanikidza kuita uye kudzivirira iyo optical fiber;iyo optical tambo ine chimiro chakareruka, huremu huremu, uye inoshanda Yakasimba;yakasarudzika groove dhizaini, nyore kupepeta, nyore kubatana, kuisirwa nyore uye kugadzirisa;yakaderera utsi halogen yemahara murazvo unodzoreredza polyethylene sheath kana murazvo unodzora PVC sheath, kuchengetedza kwezvakatipoteredza.Inogona kuenzaniswa neyakasiyana-siyana yemunda yekubatanidza uye inogona kumisa munda.
Nekuda kwekupfava kwayo uye kureruka, tambo yekudonha inoshandiswa zvakanyanya mumambure ekuwana;zita resainzi retambo yekudonha: butterfly-shaped lead-in cable yekuwana network;nekuda kwechimiro chayo cheshavishavi, inonziwo butterfly tambo, Mufananidzo 8 tambo.Chigadzirwa chacho chinoshandiswa mu: inoshandiswa kune wiring yemukati, tambo yakananga inoshandiswa nevashandisi vekupedzisira;inoshandiswa kuunza tambo dzemaziso muzvivako;inoshandiswa kune indoor wiring yevashandisi muFTTH.
