Kuchengetedza panguva yekuvakwa kweFTTH
Tichifunga nezve yakafara tarisiro ye optical network mune ramangwana, yakakwanisa kuve nechokwadi chekuti FTTH ichava Iyo huru maitiro ekuvandudza mune ramangwana.Panyaya iyi, zvinofanirwa kutarisa pakuvakwa kweFTTH optical network, kunyanya kuvakwa muchikamu cheFiber-optic yekupinda, kuitira kuti uwane chinangwa chese chekuvandudza hutano hwebasa uye yese data yekufambisa network.
Muchidimbu, pane mapoinzi maviri makuru anofanirwa kucherechedzwa mukuita kwekuvaka kweFTTH fiber kumba.
Donhedza tambo sarudzo
Parizvino inoshandiswa FTTH indoor optical fiber selection is butterfly-shaped optical fiber cable, inongonzi butterfly optical cable.Rudzi urwu rwefiber optic tambo inogona kugovaniswazve kuita yemukati tambo uye yekuzvitsigira tambo.Iwo akanyanya kufanana muchimiro, akashongedzerwa nenhengo dzinosimbisa uye jaketi pamativi ese efiber.Musiyano ndewekuti iyo yekuzvitsigira optical tambo pachayo inobatanidzwawo parutivi netambo yakaturika, iyo inogona zvinobudirira kuvandudza mechanical zvinhu zvetambo pachayo.
Mukusarudza butterfly optical cables, zvinofanirwa kucherechedzwa zvakare kuti indoor wiring optical cables inogona kukamurwa kuita mhando mbiri dzesimbi dzinosimbisa nhengo uye dzisiri-simbi inosimbisa nhengo maererano neakasiyana ekusimbisa nhengo.Kusiyana neizvi, nhengo dzisiri dzesimbi dzinosimbisa ibutterfly optical cables.Simba remagetsi rinokwanisa kutsungirira idiki, saka kuitira kuti isakonzere kukuvadza kune optical fiber core, simbi-yakasimbiswa chikamu butterfly optical fiber tambo dzinowanzo shandiswa, uye iyo isiri-simbi inosimbisa chikamu butterfly optical fiber tambo inongoshandiswa mukati. nguva apo pane chinodikanwa chepamusoro chekudzivirira mheni.
Drop cable installation
Iko kuchengetedzeka kweiyo yekugara fiber optic tambo inoda kutarisisa zvinhu zviviri.Imwe ndiyo kuchengetedzwa kwetambo ye optical pachayo mukugadzirisa kwekupinda mumba, uye imwe ndiyo nzira yekurapa tambo ye optical mukugadzirisa.
Kune yekutanga, chinangwa chebasa chiri pakugadzika kwePVC pombi, nekuti haisi yega yega tambo yekupinda shaft munzvimbo yemusha iripo, asi kune yekupinda nharaunda isina shaft, PVC pombi inodiwa.Nokuda kwemamiriro ezvinhu aya, inofanira kutanga yaonekwa kuti zvinyorwa zvepombi yePVC zvinogona kusangana nezvinodiwa zvekuisa kwetambo, uye kutsetseka kwePVC pipe spout kunoda kuongororwa kudzivirira maburrs kana micheto inopinza kubva pakukuvadza tambo.Iyo yakaiswa. PVC pombi haifanirwe kuve nekutsemuka kana dents, uye inogona kunyatso tora basa rekuchengetedza tambo yemukati.
Kune yekupedzisira, kutarisisa kunofanirwa kubhadharwa kune mechanical masimba ayo optical cable inoda kutakura.Tambo dzakasiyana-siyana dzinoratidza kutakura zvinhu zvakasiyana-siyana. Kazhinji, kwete-metallic reinforcement yakavakirwa-mukati-mukati wiring butterfly optical cables inogona kumira 40N tensile force uye 500N/100mm compaction force, iine simbi yakasimbisa kuvaka mukati Wiring butterfly optical fiber tambo inogona kumira 100N tensile simba uye 1000N/100mm kupwanya simba.Inozvitsigira yega butterfly fiber cable inogona kumira 300N tensile force uye 1000N/100mm kupwanya simba.Mukuita basa chairo, tambo ye optical inofanira kusarudzwa maererano nenzvimbo dzakasiyana dzekushanda.
Mukusarudza butterfly optical cables, zvinofanirwa kucherechedzwa zvakare kuti indoor wiring optical cables inogona kukamurwa kuita mhando mbiri dzesimbi dzinosimbisa nhengo uye dzisiri-simbi inosimbisa nhengo maererano neakasiyana ekusimbisa nhengo.Kusiyana neizvi, nhengo dzisiri dzesimbi dzinosimbisa ibutterfly optical cables.Simba remagetsi rinokwanisa kutsungirira idiki, saka kuitira kuti isakonzere kukuvadza kune optical fiber core, simbi-yakasimbiswa chikamu butterfly optical fiber tambo dzinowanzo shandiswa, uye iyo isiri-simbi inosimbisa chikamu butterfly optical fiber tambo inongoshandiswa mukati. nguva apo pane chinodikanwa chepamusoro chekudzivirira mheni.
