Ko nga raru ka pa ki te whakaurunga me te whakamahi i nga whakawhiti whakawhiti muka
Hipanga 1: Tuatahi, ka kite koe mena kei te mau te tohu o te kaitahuri muka, te kōwae whatu ranei me te tohu tauranga takirua takahuri?
1.Mehemea kei runga te tohu tauranga whatu (FX) o te A transceiver me te tohu tauranga whatu (FX) o te B transceiver kaore i te rama, ko te he kei te taha A transceiver: kotahi pea ko: A transceiver (TX) tuku whatu Kua pakaru te tauranga na te mea karekau te tauranga whatu (RX) o te B transceiver e whiwhi tohu whatu.Ko tetahi atu pea he raruraru kei tenei hononga muka o te A transceiver (TX) tauranga whatu, penei i te marama. kua pakaru te pekepeke.
2.Ki te kore te tohu o te tauranga whatu (FX) o te transceiver e whakamarama ana, whakatauhia mehemea he hononga whakawhiti te hononga muka.Ko te peke muka he hono whakarara, ko tetahi atu he hononga-whakawhiti.
3.Ko te tohu takirua (TP) e kore e marama.Me mohio kei te he, kei te he ranei te hono o te taura takirua.Tena koa, whakamahia te kaiwhakamaatau mo te haere tonu ki te tirotiro.
4. Ko etahi o nga transceivers e rua nga tauranga RJ45: (ToHUB) e tohu ana ko te raina hononga e hono ana i nga whakawhiti he raina tika.(ToNode) e tohu ana ko te raina hononga e hono ana i nga whakawhiti he raina whakawhiti.
5.Ko etahi o nga kaikawe he whakawhiti MPR i te taha: ko te raina hononga e hono ana i nga whakawhiti he aratau raina tika.
Hipanga 2: Tātarihia mena he raru kei te peke muka me te taura?
1.Optical fiber connection on-off detection: te whakamahi i te rama rama laser, te ra, me etahi atu hei whakamarama i te peke muka.Tirohia mena he rama ka kitea ki tera pito?Mena ka kitea te marama, kaore i pakaru te peke muka.
2.Cable break detection: te whakamahi i te rama laser, te ra, te rama hei whakamarama i te hononga taura, te hono ranei.Tirohia mena he rama ka kitea ki tera pito?Mena ka kitea te marama, kaore te taura e pakaru.
Hipanga 3: He he te tikanga haurua/taarua katoa?
Ko etahi o nga kaiwhakawhitiwhiti he whakawhiti FDX ki te taha: te taapiri katoa;Whakawhiti HDX: haurua matarua.
Hipanga 4: Ma te whakamahi i nga taputapu taputapu hiko hiko
Ko te mana kanapa o te whakawhiti whatu, kōwae whatu ranei i raro i nga tikanga noa: multimode: -10db–18db;aratau kotahi 20km: -8db–15db;aratau kotahi 60km: -5db–12db Mēnā kei waenga i te -30db–45db te mana maramara o te kaiwhakawhiti whatu, ka taea te whakatau he raru kei tenei kaiwhakawhiti.
Me aro atu nga kaiwhakawhitiwhiti whatu ki nga take
Mo te ngawari, he pai ake te ahua o te patai me te whakautu, ka taea te whakatutuki i te tirohanga.
1. Kei te tautoko tonu te transceiver whatu ki tonu-rua me te haurua-rua?
Ko etahi maramara i runga i te maakete ka taea anake te whakamahi i te taiao matarua-katoa i tenei wa, kaore e taea te tautoko i te haurua-rua.Mena ka hono atu koe ki etahi atu rama o te whakawhiti (SWITCH) ranei te hub (HUB), a ka whakamahia e ia te aratau haurua-rua, ka tino paopaohia me te ngaro o te paatete.
2.Kua whakamatauria mo te hononga ki etahi atu whakawhiti whakawhiti muka?
I tenei wa, he nui ake nga transceivers optical i runga i te maakete.Hei tauira, ki te kore i whakamatauria te hototahi o nga momo momo whakawhiti whakawhiti i mua, ka puta ano te mate o te paatete, te wa roa o te tuku, me te tere me te puhoi.
3. He taputapu haumaru hei aukati i te ngaro o te paatete?
Ko etahi o nga kaihanga e whakamahi ana i te aratau whakawhiti raraunga rehita ki te whakaiti i nga utu i te wa e hangaia ana nga transceivers muka whatu. mate pākete.
4.Temperature urutau?
A, no te whakamahia te transceiver muka whatu ake, ka whakaputa i te wera nui.Ina he tiketike rawa te pāmahana (kaore i neke ake i te 50 °C), ahakoa te mahi a te kaiwhakawhiti muka whatu he mea tika kia whakaarohia e nga kaihoko!
5. He paerewa IEEE802.3u?
Mena ka tutuki te kaiwhakawhiti whatu ki te paerewa IEEE802.3, ara, ka whakahaerehia te wa whakaroa ki te 46 paraka.Mena ka neke ake i te 46 moka, ka whakapotohia te tawhiti e tukuna ana e te kaiwhakawhiti whatu.
6.Ratonga muri-hoko:
Kia tere ai te whakautu a te ratonga i muri i te hokonga, e taunaki ana kia hokona e nga kaihoko nga transceivers muka-whatu kia rite ki te kaha o te kaihanga, te hangarau, te ingoa me etahi atu kamupene.
