ADSL - he aha te mea te reira? Ko te parau tumu o te mahi, te tere mōrahi, te huapai me ngā huakore o te hangarau ADSL

ADSL - he hangarau he wāhi hangarite ki te Internet. Ko reira te hanganga hangarite, me te taea te pūnaha te mahi ki i te tere o pūhui, pa ake ki te 8 Mbit / s. ADSL-hangarau, tatau nei te auau te tuku ake ki te 1 Mbit / s, mahi i te tawhiti toharite o 5 km. I teie mahana, titiro tatou ki te mea ahua o te momo hononga, me te pehea te mahi i te reira.

Ko te kōrero o

I mua i whakahoki te pātai: - kawea tatou ki tou aro te raraunga iti hītori "ADSL aha te mea te reira,?". Hoki te wā tuatahi te hanga o hononga nui-tere korero i roto i te mutunga o nga 80 ', ka ko te Internet noa i roto i tona puka hou anake te pokenga. Tona mahi matua i roto i 1989 ko te whakapai ake me te ao hou, o te tuku raraunga hangarau i runga i waea waea parahi. I hanga tairitenga-ki-mamati faafariuraa te nuinga mo te tuku tere o ngā mōhiohio i waenganui i te ngā ratonga pāhekoheko, kēmu ataata, ngā kōnae ataata, me te ki te whakarato uru mamao tonu ki te LAN me ētahi atu pūnaha whatunga.

Modern ADSL-hangarau: te parau tumu mahi

hāngai whatunga Mahi i runga i te raina kaitango mamati e whakarato whai wāhi ki te Internet te waea takere. Ko ngā rārangi waea mā te whakamahi i te tohu tairitenga mō ngā karere reo. hangaia ADSL-hononga kei te pera e te tahuri te tohu tairitenga ki mamati me te tukua atu tika reira ki te rorohiko. I te wa ano, i roto i te rerekē ki te pouwhanga Waea-ake kua tawhitotia, ngā pūrere e hāngai ana ADSL-e kore e aukati i te aho waea, me te tuku i te whakamahi o tohu mamati me tairitenga wā kotahi.

Ko te ngako o te hangarau (hangarite) Ko e whiwhi te kaitango he nui nui o te raraunga - waka taumai, me i tahaki tuku he iti o ngā mōhiohio - te waka awa. Ka rite ki te tikanga he taumai katoa o te ihirangi: ataata me pāpāho kōnae, tono, ngā hōtaka, whakairoiro ngā. E heke iho e tuku mōhiohio nui anake hangarau - ngā whakahau me pātai, īmēra, me ētahi atu tūemi iti. Ko te karawhiti Ko e te auau i te whatunga ki kaitango he maha ngā wā tere teitei i te kaiwhakamahi.

Ko te painga tino nui e nohoia ana e te ADSL-hangarau ko tona pūtea me te kakama. Ko te take i whakamahia e te pūnaha te waea parahi waea taua. Ko te maha o takirua miro i roto ratou, o te akoranga, nui nui te maha o ngā āhuatanga rite i roto i pouwhanga taura. Otiia i te wa ano e kore e hiahia ana ki te hanga i tetahi ao hou o te whakawhiti taputapu, me te hanga hou matatini. hono ADSL te he pūmanawa ki te whakahaere me te whirihora momo nohopuku, me te hou o ngā pouwhanga.

He aha te taputapu te whakamahia hoki tenei hononga?

I roto i te tikanga mo te hangarau ki te mahi, te whakamahi i ngā momo motuhake o ngā pouwhanga, e rerekē i roto i to ratou hanganga, hoahoa, momo o hononga:

• PCI-pouwhanga (pūrere rorohiko ā).
• pouwhanga waho ki te momo o te hononga USB.
• Pūrere ki te momo atanga Itarangi.
• Pouara, pouara ki Itarangi ara iahiko.
• momo motuhake o ngā pouwhanga (mo ngā kamupene haumarutanga, rārangi waea tūmataiti).
• Pouara ki ngā ā o Wi-Fi te uru.

Atu taputapu: pūritua me microfilters

Me kore tatou e wareware i hoki te hononga o te gadget pērā i te ADSL-pouwhanga, pūritua me microfilters hiahiatia. E tīpakohia Pūrere i roto i runga i te hoahoa o te taura waea. I roto i te āhuatanga i reira hanga te putanga taura te (taea te kawea atu ranei) ki te tareka whakamahia hongere pouwhanga me Kairitu waea te. I roto i rānei take, e hiahia ana koe ki te hoko i te microfilter, tāutatia nei i runga i nga waea e he reira i roto i te ruma.

Ko te mahi matua o te Kairitu ko ki wehe te auautanga - reo (0,3-3,4 kHz) me tono tika i te pouwhanga (25 kHz-1.5 MHz). Ko reira i roto i ngā tenei ara te mahi tukutahi o te pouwhanga me te waea e kore e nei pokanoa ki ia atu, me te kore e pokanoa. He kiato pūritua me kore e meinga raruraru faufaa. rite rawa pouaka Miniature te ki e toru terminals me he taimaha iti.

goodies

E kua te painga o te ADSL-hangarau? Tenei ko etahi o ratou:

• High tere tuku raraunga. ADSL taea koe ngāwari ki te whakawhiti kōnae o tetahi rahi, kahore te whanga roa. Kei te pai ake tonu te hangarau, me te tere te whakanui ake, tino whakawhänui i te wheako kaitango.
• hononga ahokore. Hei whakamahi i te-pūnaha ADSL, ki Kahore he aha whakawhānui i te taura ki te waea, me te whakaturia te rota o te taputapu. Nui haere tika, te kounga, me te taumahinga o te whatunga.
• No pokanoa i runga i te raina waea. mahi ADSL-pouara i roto i te aratau tu-anake, me te kore e hanga tetahi raruraru mo te waea. Waea me ngaru te wāhi mariko taea e tino noa.
• Motukore ADSL uru Ipurangi. He aha te mea te reira? tikanga o tēnei e ia kore e hoatu e te whatunga rahunga. E kore e te hangarau rapua e te reconnection. whai te kaiwhakamahi te Ipurangi tonu a taea e te ipurangi ra katoa, me te te po.
• Tika me te pūmautanga. Ki te rā, ADSL ko te momo tino pono o te hononga Ipurangi.
• Moni. Ko te utu o te hononga ADSL me tāuta te pouwhanga ki he iti he pouara me e kore e patua te pūtea te whānau.

hapehape

1. No tiaki ki crosstalk. Ki te ka te hono tetahi teihana ki te maha kiritaki tatini whakawhirinaki i runga i te tere tiketike e kore te mea e tika ana. kaiohauru atu i roto i te kotahi ADSL, te raro te kounga o te tuku raraunga.
2. huakore ADSL-hangarau ahakoa kua reira, engari he torutoru ratou. taea hoki ngā te reira i te tere iti o te kaiohauru. Ko te karawhiti o ADSL he kino kitea - i te whakawhitinga kōnae kaitango ka kia roa, me te fiemālie. Ko te tikanga i te hangarau kei te matua mo te uru tere ki te Internet mo te ngaru. I tua atu, i te mōhiohio tuku i te kaiwhakamahi, e ake iti wāhi me te titau atu rauemi.

Auau me ngā āhuatanga e pā reira

ADSL Ko te hangarau Ipurangi nui-tere, engari uara ao me tātai tīariari. Hoki ia kaitango takitahi me te auau takitahi whakaritea e te huinga o ngā āhuatanga. Tae atu etahi o ratou e pā i te tika, me te kounga o te taputapu. Na reira, ki te kawe i roto i te tāutanga o ngā pouwhanga me pouara ngaio pai.

Ko te take matua mō te tere iti ADSL-pūhui ko te kounga o te raina kaitango. Kei te korero tatou e pā ana ki te aroaro o körere piriti, ratou huru, diameter me te roa o te waea. Attenuation Ko te putanga tika o te nui haere roa o te aho kaitango, a taea whakaiti pokanoa tika ki te roha o te diameter waea. e kore e roa ADSL-hongere paerewa nui 5 km - ngā tino pai mō te tiketike-tere tuku raraunga.

āhuatanga tere

Whakaritea ki ētahi atu hononga Ipurangi, tino toa ADSL i roto i hangarau tere. Tairitenga pouwhanga homai he mōrahi o 56 kbit / s, i whakaaetia kua te ADSL i roto i nga ra wawe o tona ahua ki te tuku mōhiohio ka kīia e ki runga, ki te 144 Kbit / s. ADSL-hangarau, te tere mōrahi nei whakaritea ano e te āhuatanga o te pouwhanga me taea tae 2048 Mbit / s, ki te arotau i te tuku mōhiohio. rārangi Digital nui whakarei ake i te wheako kaiwhakamahi, me te mau mai i te reira i tera taha o te rohe, ara, ki te whai koe i rorohiko maha hono, waea pūkoro, papa me ētahi atu gadgets.

opuaraa hangarau

He tawhiti whai wāhitanga me ngā rauemi hangarau ADSL i ruha. Ahakoa ADSL2 paerewa, me te ADSL2 +, whakaurua hoki i roto i te waenganui 2000 a, tonu noho tika me te whai wāhitanga. te, i roto i te meka, anake te hangarau e taea whakarato i tētahi wāhi ki te ipurangi whānui, kahore arumanga me pūmanawa raruraru, na te whakataetae mo te maha atu ngā huarahi ki te hono i te reira ki te Internet.
