Shabakadda topology-ga sida caadiga ah loo isticmaalo joojinta qaab dhismeedka baska, ma taageerto shabakad wareegsan ama xidig leh.Dhammaan node waa taxane isku xiran hal bas waa doorasho wanaagsan, sawirka kore, topology guud ee nidaamka A8-05B ayaa lagu muujiyay.N nodes waxay ku xidhan yihiin shabakad dhibco badan.Xawaaraha sare iyo xariiqyada dhaadheer, caabbinta joojinta ayaa lagama maarmaan u ah labada daraf ee khadka si loo baabi'iyo milicsiga.Isticmaal 100 Ω iska caabin ah labada daraf (waxay u baahan yihiin kaliya haddii dhererka siligga> 2km).Shabakadda waa in loo qaabeeyaa sidii hal xariiq oo leh dhibco badan, oo aan ahayn xiddig ahaan.In kasta oo dhererka guud ee fiilada laga yaabo in uu ka gaaban yahay qaabaynta xiddigaha, joojinta ku filan mar dambe suurtagal maaha oo tayada calaamaduhu si weyn ayay hoos u dhigi kartaa.Jaantuska 1 ee muujinaya xiga, b, d, f waa xidhiidh sax ah iyo a, c, e waa xidhiidh khaldan.

Markaad isticmaalayso siligga shabakadda gaashaandhigga (STP), waa inay ilaalisaa sii wadida lakabka gaashaandhigga ee siman, oo ku xidh Earth hal dhibic, sida ku cad jaantuska.
Silig baa loo baahan yahay
Nidaamka loo isticmaalo CAT-5E UTP iyo STP cable.
Sidee loo doortaa fiilada CAT-5E ee aqoonta leh?
Iska caabbinta silig kasta waa in ay ahaataa ≤35Ω marka dhererku yahay qiyaastii 305M (dhererka FCL).
Albaabka albaabka ilaa Korontada waxaa loo adeegsaday RVV4*0.5, si loo xiro RVV2*0.5.
Digniin:
Sawirka albaabka albaabka si buuxda uguma soo muuqan doono shaashadda qolka Visual Room-site-ka marka qolka-goobku aad uga duwan yahay sahayda fiidyaha, meelaha ku habboon ee baska dhismaha si loo kordhiyo sahayda korontada ayaa xallin karta dhibaatadan.Fiidiyowga guud ee korontada ka imaanaya qolka-muuqaalka ee masaafada ugu badan kama badan karto 30 mitir.

Waa maxay sababta aan RJ-45 loogu isticmaalin isku xirka?
Sababtoo ah heerka RJ-45 wuxuu u samaysan yahay gudaha gudaha iyadoo la isticmaalayo oo keliya, waa liitaa qoyaanka oo si fudud ayaa loo wasakheeyey ama loo oksaydhiyay.Haddii madaxa RJ-45 uu jabo, waxaa jira xirfadlayaal haysta qalab xirfadeed oo loo baahan yahay si loo hagaajiyo qaladka, tani waxay horseedi doontaa kharashyo dayactir oo sarreeya.
Scotchlok waa waxa aan u baahanahay.In ka badan 45 sano ka hor, 3M waxay soo bandhigtay isku xidhaha dahaarka asalka ah ee warshadaha - isku xidhka Scotchlok UR.Maanta, iyada oo ay korodhay baahida loo qabo shabakadaha xawaaraha-sare iyo-bandwidth-sare, taxanaha dhammaystiran ee xirayaasha 3M iyo aaladaha ayaa mar kale horumaray.Fadlan booqo www.3M.com si aad u hesho macluumaad dheeraad ah Scotchlok.
