Chii chinonzi Fiber Drop Cable?
Iyo fiber inodonhedza tambo ndiyo optical communication unit (optical fiber) iri pakati, mbiri dzakafanana dzisiri-simbi yekusimbisa (FRP) kana nhengo dzekusimbisa simbi dzinoiswa pamativi ese, pamwe nedema kana ruvara polyvinyl chloride (PVC) kana yakaderera-utsi halogen. -isina zvinhu (LSZH) , Yakaderera-utsi, halogen-isina, murazvo-retardant) sheath.Nekuda kwechimiro chayo cheshavishavi, inonziwo butterfly optical cable uye nhamba 8 optical cable.
Chimiro uye Rudzi rweFiber Drop Cable:
Iyo fiber inodonha tambo yakakamurwawo mukati uye kunze.Iyo yakajairwa fiber inodonha tambo ine yakajairwa nhamba-sere chimiro;nhengo mbiri dzakafanana dzakasimba, pakati payo inonzi optical fiber, inonyanya kushandiswa mumba;iyo inozvitsigira fiber inodonha tambo inonyanya kushandiswa kunze, mune yakajairwa faibha inodonha tambo gobvu simbi waya yekumisa waya inowedzerwa kune chimiro.
Simba Nhengo, iyo fiber inodonhedza tambo ine simbi simba nhengo inogona kuwana yakakura tensile simba uye inokodzera kure-kure mukati meimba yakachinjika wiring kana chinhambwe-chinhambwe chemukati vertical wiring.Iyo simbi simba nhengo faibha kudonhedza tambo haina kusimbiswa neyakajairwa phosphating simbi waya, asi ine yakakosha yemhangura-yakapfeka simbi waya zvinhu, izvo zvinogona kudzivirira kukuvadzwa kweiyo optical tambo inokonzerwa nespringback uye mhepo inokonzerwa nephosphating simbi waya mukuvaka engineering.Iyo isiri-simbi simba nhengo fiber kudonhedza tambo inoshandisa FRP sechinhu chinosimbisa, icho chakakamurwa kuita marudzi maviri ekfrp uye gfrp.Kfrp yakapfava uye yakawanda ductile, yakareruka uye inodhura.Inogona kuona yese isiri-simbi yekuwana imba uye ine yepamusoro yekudzivirira mheni kuita.Inokodzera kusuma kubva kunze kuenda mukati.
Outer Jacket, PVC kana LSZH zvinhu zvinowanzo shandiswa kune yekunze bhachi re fiber inodonha tambo.Iyo murazvo unodzoreredza kuita kweLSZH zvinhu zvakakwirira kupfuura izvo zvePVC zvinhu.Panguva imwecheteyo, kushandiswa kwezvinhu zvitema LSZH zvinogona kuvhara ultraviolet erosion uye kudzivirira kuputika, uye inokodzera kuiswa kubva kunze kusvika mukati.
Optical Fiber Type, mafiber akajairika efiber drop cable iG.652.D, G.657.A1, G.657.A2.Iyo optical fiber mu fiber drop cable inoshandisa G.657 duku bending radius fiber, iyo inogona kukotama pa20mm.Radius kuisa kwakakodzera kupinda mumba muchivako nenzira yepombi kana mutsara wakajeka.G.652D single-mode fiber ndiyo imwe-mode fiber ine zviratidzo zvakasimba pakati pemazinga ose eG.652 uye inodzokera shure zvachose.Yakafanana neyakajairwa G.652 faibha uye pari zvino ndiyo inonyanya kushandiswa mumaguta makuru network.Kusina-kupararira kwakashandura imwe-modhi fiber.
Zvimiro zveFiber Drop Cable:
1. Huremu uye dhayamita diki, murazvo unodzoreredza, nyore kupatsanura, kuchinjika kwakanaka, kunenge kwakanaka kubhenda kuramba uye nyore kugadzirisa;
2. Zviviri zvakafanana FRP kana simbi yakasimbiswa zvinhu zvinogona kupa zvakanaka compression kuramba uye kudzivirira optical fiber;
3. Chimiro chakareruka, uremu huremu uye kuita kwakasimba;
4. Yakasarudzika groove dhizaini, nyore kupepeta, nyore kubatanidza, kurerutsa kuisa uye kugadzirisa;
5. Yakaderera-utsi halogen-isina flame-retardant polyethylene sheath kana kuchengetedzwa kwezvakatipoteredza PVC sheath.
Zvishandiso zveFiber Drop Cable:
1.User indoor wiring
Indoor butterfly cables anowanikwa mune zvakatemwa senge 1 core, 2 cores, 3 cores, 4 cores, etc. Single core cables dzinofanira kushandiswa kune vanogaramo vashandisi kuwana butterfly optical cables;kune vashandisi vebhizinesi kuti vawane butterfly Optical cables, 2--4 core cables dhizaini.Kune mhando mbiri dzeshavishavi-shavi pamba optical cables: nhengo dzisiri dzesimbi dzinosimbisa uye nhengo dzinosimbisa simbi.Tichifunga nezvezvinhu zvekudzivirira mheni uye kupindira kwakasimba kwemagetsi, kwete-simbi inosimbisa nhengo butterfly optical cables inofanira kushandiswa mumba.
2.Vertical uye horizontal wiring muchivako
Senge wiring yemukati yemushandisi, iyo yakachinjika wiring hainyanyi kunetsa pane yekuona tambo, asi yakatwasuka wiring inoda kuti tambo yemaziso ive neimwe simba rekusimba kwekuita, saka isu tinofanirwa kufunga nezve kusimba kwetambo yekudonha tambo. pakutenga
3.Kuzvitsigira pamhepo-pamba wiring
Iyo inozvitsigira "8" wiring optical tambo inowedzera simbi inorembera waya unit pahwaro hwefiber inodonhedza tambo, saka ine simba rakawanda rekusimba, inogona kushandiswa kuisa pamusoro, uye yakakodzera kune yekunze wiring mukati memukati wiring nharaunda. .Tambo yemaziso inoradzikwa nepamusoro-soro kunze, iyo simbi inorembera waya unit inogurwa isati yapinda mumba, uye yakagadzikwa pane yakakosha mubati, uye yasara optical tambo inobviswa simbi yakarembera waya uye inopinzwa mukamuri ine tambo. fiber drop cable.
4.Pipeline kumba wiring
Pipe-mapping optical cables uye kuzvitsigira "8" wiring optical cables ese ari mukati nekunze akasanganiswa optical cables, anogona kuenderana nemukati nekunze nharaunda, uye akakodzera FTTH sumo kubva kunze kuenda mukati.Nekuda kwekuwedzera kwekunze sheath, kusimbiswa uye mvura-yekudzivirira zvinhu pahwaro hwefiber inodonha tambo, iyo pombi-mapping optical cable yakavandudza kuoma uye kusapinda kwemvura kuita, uye inokodzera kunze kwekuisa pombi.
