Umuyoboro wa Topologiya usanzwe ukoreshwa muguhagarika bisi, ntabwo bishyigikira umuyoboro cyangwa inyenyeri. Byose node ni serial ihujwe na bisi imwe ni amahitamo meza, ku ishusho hejuru, umuyoboro rusange wa topologiya ya a8-05b irerekanwa. N node ihujwe murusobe rwinshi. Kumuvuduko mwinshi kandi umurongo muremure, ingufu zo kurangiza zirakenewe kumpera zombi zumurongo kugirango ukureho ibitekerezo. Koresha 100 ω abaturwa ku mpande zombi (bakeneye gusa niba uburebure bwinsinga> 2km). Umuyoboro ugomba gukorerwa nkumurongo umwe ufite ibitonyanga byinshi, ntabwo ari inyenyeri. Nubwo uburebure bwuzuye bwigihe gito mubiboneza byinyenyeri, guhagarika bihagije ntibishoboka ukundi hamwe nubuziranenge bwibimenyetso bishobora gutesha agaciro. Mu gishushanyo 1 cyerekanaga ubutaha, b, d, f ni isano nziza na a, c, e ni isano itari yo.
Igishushanyo 1
Iyo ukoresheje umuyoboro wa Shield (STP), ugomba gukomeza gukomeza urwego rukingira, kandi uhuza isi imwe, nkuko bigaragara mu gishushanyo
Insinga irasabwa
Sisitemu yakoresheje injangwe-5e Utp na STP umugozi.
Nigute wahitamo injangwe yujuje ibisabwa-5e?
Kurwanya buri nsinga bigomba kuba ≤35ω mugihe uburebure bugera kuri 305m (uburebure bwa FCL).
Sitasiyo ya Station kuri RVV4 * 0.5, Gufunga Byakoreshejwe RVV2 * 0.5.
UMUBURO:
Ishusho yumuryango ntizagaragaza byuzuye muri ecran yuburyo-bwa sitasiyo igaragara mugihe cyamashanyarazi ya videwo, ahantu hakwiye muri bisi yo kubaka irashobora gukemura iki kibazo. Imbaraga rusange zamashanyarazi ziva mubyumba biboneka hagati yintera ntarengwa ntishobora kurenga metero 30.
Igishushanyo 2
Nyamuneka koresha Scotchlok kugirango uhuze insinga 2

Ubona gute ukoresheje RJ-45 Kubuhuza?
Kubera ko RJ-45 isanzwe igizwe ku nzu ikoresheje gusa, ni umukene-gikennye kandi byoroshye kubyanduye cyangwa okiside. Niba umuyobozi wa RJ-45 yamenetse, hari abanyamwuga bakora ibikoresho byumwuga basabwa gusana amakosa, ibi bizaganisha kumafaranga yo kubungabunga.
Scotchlok nibyo rwose dukeneye. Ubu hashize imyaka 45, 3m yamenyesheje inganda zo kwimura uruganda rwumwimerere - Scotchlok ihuza Ur. Muri iki gihe, hamwe no kwiyongera kwihuta-kwihuta cyane kandi hejuru-bande, urukurikirane rwuzuye rwabahuza 3m hamwe nibikoresho byongeye guhinduka.
