Topology pahi whatunga
Ko te topology whatunga e whakamahia nuitia ana ko te whakamutu i te hanganga pahi, kaore i te tautoko i te whatunga porowhita, ahua whetu ranei. Ko nga pona katoa he rangatū e hono ana e tetahi pahi he pai te whiriwhiri, i te pikitia i runga ake nei, ka whakaatuhia te topology whatunga whanui o te punaha A8-05B. N nga pona e hono ana ki te whatunga ira maha. Mo nga tere teitei me nga raina roa, ko nga aukati whakamutu e tika ana ki nga pito e rua o te raina hei whakakore i nga whakaata. Whakamahia nga parenga 100 Ω ki nga pito e rua (mehemea anake te roa waea > 2km). Me hoahoa te whatunga hei raina kotahi me nga maturuturu maha, kaua hei whetu. Ahakoa he poto ake pea te roa o te taura i roto i te whirihoranga whetu, kare e taea te whakamutu tika, ka tino heke te kounga o te tohu. I te Hoahoa 1 i whakaatu i muri mai, b, d, f he hononga tika, a, c, e he hononga.
Hoahoa 1
I te wa e whakamahi ana i te waea whatunga whakangungu rakau (STP), Me mau tonu te mau tonu o te paparanga whakamarumaru o te maeneene, me te hono i te whenua ki tetahi waahi, penei i te whakaahuatanga.
Waea e hiahiatia ana
I whakamahia e te punaha te CAT-5E UTP me te taura STP.
Me pehea te whiriwhiri i te taura CAT-5E whai mana?
Ko te parenga o ia waea me ≤35Ω ina he 305M te roa (FCL roa).
Door-station ki Power Supply whakamahia RVV4*0.5, ki te maukati whakamahia RVV2*0.5.
Whakatupato:
Ko te pikitia o te teihana kuaha e kore e tino whakaatu ki te mata o te teihana Ruma-Ruma i te wa e rerekee ana te teihana-Rua mai i te tuku hiko ataata, i nga waahi e tika ana i roto i te whare pahi hei whakanui i te hiko ka taea te whakaoti i tenei raru. Ko te tuku hiko ataata whanui mai i te teihana-Ruma-ataata o te tawhiti teitei kaore e neke atu i te 30 mita.

He aha te whakamahi RJ-45 mo te hononga?
Na te mea ko te paerewa RJ-45 he mea hanga mo te whakamahi i roto i te kuaha anake, he ngoikore te makuku-tohu me te tino ngawari ki te paru, ki te waikura ranei. Mena ka pakaru te RJ-45 Head, kei reira nga tohunga e mau ana i nga taputapu ngaio e hiahiatia ana hei whakatika i te he, ka nui ake nga utu tiaki.
Ko Scotchlok te mea e hiahiatia ana e matou. Neke atu i te 45 tau ki muri, i whakauruhia e 3M te hononga whakanekehanga arai taketake o te umanga - te Scotchlok Connector UR. I tenei ra, na te nui haere o te hiahia mo nga whatunga tere-tere me te whanui-nui, kua tipu ano te raupapa katoa o nga hononga 3M me nga taputapu. Tena koa tirohia www.3M.com mo etahi atu korero a Scotchlok.
