Drop Optical Cable inonziwo Bow-type yekudonha tambo (yemukati wiring). Iyo optical communication unit (optical fiber) inoiswa pakati, uye maviri akaenzana asiri-metallic simba nhengo (FRP) kana nhengo dzesimbi dzesimbi dzinoiswa pamativi ese. Pakupedzisira, yakawedzera dema kana chena , Gray polyvinyl chloride (PVC) kana yakaderera-utsi halogen-isina zvinhu (LSZH, yakaderera-utsi, halogen-isina, inodzoreredza murazvo) sheathed. Iyo yekunze tambo yeganda ine inozvitsigira yakaturika waya muchimiro-8 chimiro.
Kazhinji, kune G657A2 optical fiber, G657A1 optical fiber, uye G652D optical fiber. Kune mhando mbiri dzekusimbisa pakati, simbi yekusimbisa uye isiri-simbi FRP yekusimbisa. Masimbi ekusimbisa anosanganisira ① phosphated simbi waya ② copper-plated simbi waya ③ galvanized simbi waya ④ coated simbi waya (kusanganisira phosphate simbi waya uye galvanized simbi waya yakanamwa guruu). Zvisiri-simbi zvinosimbisa zvinosanganisira ①GFRP②KFRP③QFRP.
Iyo sheath yetambo yedehwe kazhinji ichena, dema, uye grey. Ichena inowanzo shandiswa mumba, nhema inoshandiswa kunze, UV-inodzivirira uye inodzivirira kunaya. Iyo sheath zvinhu inosanganisira PVC polyvinyl chloride, LSZH yakaderera-utsi halogen-isina murazvo-inodzoreredza sheath zvinhu. Kazhinji, vagadziri vanokamura LSZH yakaderera-utsi halogen-isina murazvo retardant zviyero mumhando nhatu: isingadzore murazvo, inodzoreredza murazvo kuburikidza nekutsva kwakamira kamwe chete, uye murazvo unodzoreredza mumasumbu.
Outdoor optical tambo yekurembera waya inogona kutsigira 30-50 metres. Phosphating simbi waya inotora 0.8-1.0MM, galvanized simbi waya uye rubberized simbi waya.
Yakavharwa tambo maitiro: yakakosha kubhenda inopikisa optical fiber, inopa yakakura bandwidth uye inosimudzira network yekufambisa kuita; maviri akafanana FRP kana simbi inosimbisa inoita kuti tambo ye optical ive yakanaka yekumanikidza kuramba uye kudzivirira iyo optical fiber; iyo optical tambo ine chimiro chakareruka, huremu huremu, uye inoshanda Yakasimba; yakasarudzika groove dhizaini, nyore kupepeta, nyore kubatanidza, kurerutsa kuisirwa nekugadzirisa; yakaderera-utsi halogen-isina murazvo-inodzoreredza polyethylene sheath kana murazvo-inodzoreredza PVC sheath, kuchengetedza kwezvakatipoteredza. Inogona kuenzaniswa neyakasiyana-siyana pa-saiti yekubatanidza uye inogona kupedzwa pa-saiti.
Nekuda kwekupfava kwayo uye kureruka, tambo yekudonha inoshandiswa zvakanyanya mumambure ekuwana; zita resainzi retambo yekudonha: iyo butterfly-shaped lead-in cable ye network yekuwana; nokuti chimiro chayo chakafanana neshavishavi; iyo inonziwo butterfly-shaped optical cable, Mufananidzo 8 optical cable. Chigadzirwa chinoshandiswa mu: kune wiring yemukati, mushandisi wekupedzisira anoshandisa zvakananga tambo; nokuda kwechivako chinopinda optical cable; kune wiring yemukati yemushandisi muFTTH.
