Izilumkiso ngexesha lokwakhiwa kwe-FTTH
Ngenxa yethemba lesicelo esibanzi sothungelwano olubonakalayo kwixesha elizayo, luye lwakwazi ukuqinisekisa ukuba i-FTTH iya kuba Yeyona ndlela iphambili yophuhliso lwexesha elizayo. Kule meko, kuyimfuneko ukugxila kulwakhiwo lwe-FTTH network optical, ngakumbi ukwakhiwa kwinqanaba lokungena kwe-Fiber-optic, ukuze kufezekiswe injongo epheleleyo yokuphucula umgangatho womsebenzi kunye nenethiwekhi yokuhanjiswa kwedatha yonke.
Ngamafutshane, kukho amanqaku amabini aphambili ekufuneka aqwalaselwe kwinkqubo yolwakhiwo lwefiber yeFTTH ekhaya.
Lahla ukhetho lwentambo
Ngoku esetyenziselwa i-FTTH ukhetho lwangaphakathi lwefiber optical fiber yintambo yefiber optical fibre emile okwebhabhathane, ebizwa nje ngokuba yintambo yokukhanya yebhabhathane.Olu hlobo lwentambo ye-fiber optic inokwahlulwa ngakumbi ibe yintambo yangaphakathi kunye nentambo ezixhasayo.Ngokusisiseko ziyafana kulwakhiwo, zixhotyiswe ngamalungu okomeleza kunye neebhatyi kumacala omabini osinga.Umahluko kukuba i-self-support optical cable ngokwayo nayo idibaniswe ngasecaleni kunye nentambo yokuxhoma, enokuphucula ngokufanelekileyo iimpawu zemishini yekhebula ngokwayo.
Ekukhethweni kweentambo ze-butterfly optical, kufuneka kuqatshelwe ngakumbi ukuba iintambo ze-wiring zangaphakathi zinokwahlulwa zibe ziindidi ezimbini zamalungu okuqinisa isinyithi kunye namalungu angenawo isinyithi ngokwamalungu ahlukeneyo okuqinisa.Ngokwahlukileyo koko, amalungu angeyontsimbi yokuqinisa ziintambo zebutterfly optical.Amandla omatshini anokunyamezela mancinci ngokwentelekiso, ukuze angonakali kumbindi wefiber optical, iintambo ze-butterfly optical fiber zisetyenziswa ngokubanzi, kwaye i-non-metallic reinforcing component butterfly optical fiber cable isetyenziswa kuphela apha. amaxesha apho kukho imfuneko ephezulu yokukhusela umbane.
Ufakelo lwentambo yokuwisa
Ukhuseleko lwentambo yefiber optic yokuhlala kufuneka ithathelwe ingqalelo imiba emibini.Enye kukukhuselwa kwentambo ye-optical ngokwayo kwinkqubo yokungena ekhaya, kwaye enye yindlela yokuphatha intambo ye-optical kwinkqubo yokubeka.
Kwixesha langaphambili, ugxininiso lomsebenzi luxhomekeke ekumiseni i-PVC piping, kuba akuyiyo yonke i-cable entry shaft kwindawo yasekhaya ekhoyo, kodwa kwimeko yokungena ngaphandle kwe-shaft, i-PVC piping iyadingeka.Kule meko, kufuneka kuqala kuqatshelwe ukuba iinkcukacha zombhobho wePVC zinokuhlangabezana neemfuno zokubeka intambo, kwaye ukugudiswa kwe-spout yombhobho wePVC kufuneka kuhlolwe ukukhusela i-burrs okanye imiphetho ebukhali ekonakalisa intambo. Umbhobho wePVC akufanele ube naziphi na iintanda okanye izibonda, kwaye unokuthatha ngokufanelekileyo uxanduva lokukhusela intambo yayo yangaphakathi.
Kulo mva, ingqalelo kufuneka ihlawulwe kumandla omatshini ekufuneka intambo ye-optical ithwale.Ingqwalasela ibandakanya zombini amandla okuqina kunye namandla atyumzayo.Iintlobo ezahlukeneyo zeentambo zibonisa amandla okuthwala ahlukeneyo.Ngokubanzi, i-non-metallic reinforcement eyakhelwe ngaphakathi kwi-wiring ye-butterfly optical cables inokumelana ne-40N tensile force kunye ne-500N/100mm compaction force, ngelixa intsimbi eyomeleziweyo yokwakha yangaphakathi Intambo ye-butterfly optical fiber inokumelana ne-100N yamandla e-tensile kunye ne-1000N / 100mm amandla okutyumza.Intambo yefayibha yebhabhathane ezixhasayo inokumelana ne-300N yamandla okuqina kunye ne-1000N/100mm amandla okutyumza.Kwinkqubo yangempela yomsebenzi, ikhebula le-optical kufuneka likhethwe ngokweendawo ezahlukeneyo zokusebenza.
Ekukhethweni kweentambo ze-butterfly optical, kufuneka kuqatshelwe ngakumbi ukuba iintambo ze-wiring zangaphakathi zinokwahlulwa zibe ziindidi ezimbini zamalungu okuqinisa isinyithi kunye namalungu angenawo isinyithi ngokwamalungu ahlukeneyo okuqinisa.Ngokwahlukileyo koko, amalungu angeyontsimbi yokuqinisa ziintambo zebutterfly optical.Amandla omatshini anokunyamezela mancinci ngokwentelekiso, ukuze angonakali kumbindi wefiber optical, iintambo ze-butterfly optical fiber zisetyenziswa ngokubanzi, kwaye i-non-metallic reinforcing component butterfly optical fiber cable isetyenziswa kuphela apha. amaxesha apho kukho imfuneko ephezulu yokukhusela umbane.
