Topology ya bisi zo kuri interineti

Topoloji y'urusobe rw'itumanaho ikunze gukoreshwa mu kurangiza imiterere ya bisi, ntabwo ishyigikira umuyoboro uzengurutse cyangwa ufite ishusho y'inyenyeri. Node zose zihujwe na bisi imwe ni amahitamo meza, ku ishusho iri hejuru, topoloji rusange y'urusobe rw'itumanaho ya sisitemu ya A8-05B iragaragara. Node za N zihujwe mu muyoboro w'amanota menshi. Ku muvuduko mwinshi n'imirongo miremire, résistances zo kurangiza zirakenewe ku mpera zombi z'umurongo kugira ngo ukureho reflections. Koresha resistor za 100 Ω ku mpera zombi (bikenewe gusa niba uburebure bw'insinga ari > 2km). Umuyoboro ugomba gushushanywa nk'umurongo umwe ufite amadomo menshi, ntabwo ari nk'inyenyeri. Nubwo uburebure bwose bw'insinga bushobora kuba bugufi mu miterere y'inyenyeri, kurangiza bihagije ntibishoboka kandi ubwiza bw'ikimenyetso bushobora kwangirika cyane. Mu Gishushanyo cya 1 cyagaragaje ibikurikira, b, d, f ni uguhuza neza na a, c, e ni uguhuza nabi.

Ishusho ya 1

Mu gihe ukoresha insinga y'urusobe rw'imiyoboro (STP), ugomba gukomeza urwego rwo kurinda rugakomeza kuba rwiza, kandi ugahuza Isi ahantu hamwe, nk'uko bigaragara ku gishushanyo.

Insinga zirakenewe

Sisitemu yakoresheje insinga ya CAT-5E UTP na STP.
Ni gute wahitamo insinga ya CAT-5E ikwiye?
Uburemere bwa buri nsinga bugomba kuba ≤35Ω iyo uburebure buri hafi 305M (uburebure bwa FCL).
Sitasiyo y'umuryango ijya ku isoko ry'amashanyarazi yakoreshejwe RVV4*0.5, kugira ngo ifungure RVV2*0.5 yakoreshejwe.
Umuburo:
Ifoto ya sitasiyo y'umuryango ntabwo izagaragara neza muri ecran ya sitasiyo ya Visual Room mu gihe sitasiyo y'icyumba itandukanye cyane n'amashanyarazi ya videwo, ahantu hakwiye muri bisi y'inyubako kugira ngo hongerwe umuriro w'amashanyarazi bishobora gukemura iki kibazo. Ingufu rusange za videwo zituruka kuri sitasiyo ya videwo y'icyumba ifite intera ntarengwa ntizishobora kurenza metero 30.

Kuki utakoresha RJ-45 kugira ngo uhuze?

Kubera ko igipimo cya RJ-45 cyagenewe gukoreshwa mu nzu gusa, ntikigera ku bushuhe kandi byoroshye kwanduza cyangwa gusya. Iyo umutwe wa RJ-45 wangiritse, hari abahanga bafite ibikoresho by'umwuga bikenewe mu gusana ikibazo, ibi bizatuma ikiguzi cyo kubungabunga gizamuka.
Scotchlok ni cyo dukeneye. Mu myaka irenga 45 ishize, 3M yazanye umuyoboro wa mbere w’inganda utuma insulation ikomeza kwiyongera - Scotchlok Connector UR. Muri iki gihe, bitewe n’ubwiyongere bw’abakeneye imiyoboro yihuta kandi ifite bandwidth nyinshi, uruhererekane rwuzuye rw’imiyoboro n’ibikoresho bya 3M byongeye gutera imbere.
