FTTx - he aha te mea te reira? hangarau FTTx

Na ko te taahiraa o te whakarato kaiwhakamahi ki te uru ki te Internet, ka timata maha kamupene ki te whakamahi i te hangarau matatau, hei tauira, FTTx. Kua mutu te reira ki te kia pera utu, me te uaua rite ko reira 5-6 tau ki muri. Kei te kē kukū, te mākete ki horo'a taua ratonga. Na reira ko te reira e tika ana ki te whakaaro i roto i te taipitopito atu te ariā o FTTx. Ko, ka riro te reira mārama, ki te ruku koe ki te hangarau iho.

āhuatanga

Hei whakamahi i tetahi hangarau hou titau te whakamahi o etahi rauemi, me i roto i tenei take kahore he okotahi, ko FTTx. He aha te mea a pehea te mahi i te reira e kia whakaahuatia ake nei.

FTTx Ko te wā kano e ai denoted te huarahi whānui ki te āhua o te hanganga o te taura hanganga whatunga, i roto i nei i te kōpuku kōrero ki te wāhi etahi, tuku ki rite «x», hora te muka whatu, a atu kua tika ki UE faaineine parahi taura. Ka taea e apu i te tuku kōrero tika ki te pūrere pūrere mahi i runga i te Ipurangi ranei. Ko te tikanga whakaaro anake te taumata tinana, ka tūhono FTTx. He aha te mea te reira? Ko te tika te rārangi iho. Heoi, titau te ariā rawa te whakamahi o atu o te maha o hangarau hono me te taumata whatunga. Ngā mihi ki ngā kamupene aunui e taea ki te whakarato i kiritaki ki te whānuitanga o ngā ratonga.

He aha te mea ngā Ko te whatunga?

Ka rite ki te pūkaha matua o te whanaketanga o te hangarau FTTx tēnei wā tu te tono kiritaki nui mō te whai wāhi aunui, i te mea uaua mīharo ki te whakatutuki i te whakamahi i ADSL tuku iho. Kei te piki haere timata Optics ki te tango i pakiaka i roto i nga pa nui, a inaianei e taea e koe te haafifi i ki hanumi te ngā o ngā taumata rerekē. Tino whakamahia te hangarau, me i te kainga, wahi hanga te whai wāhi taketake ki te Ipurangi i runga i te kaupapa o te ara whatu.

whanaketanga o te opuaraa mākete

Hei mahino pai te mauri o tenei hangarau, me whai whakaaro te opuaraa whanaketanga o FTTx. He aha te mea te reira? I runga i te rohe Russian o te hanganga o te mākete o taua ratonga, tei runga i te tono mo te ihirangi kounga tiketike e kore anake, engari ano hoki i runga i te maha o ngā kaupapa hanganga o te rahi nui, me te nui haere whakataetae i roto i ngā kaiwhakarato o ratonga aunui. Kua auraa te whanaketanga hihiri o te hanganga o te whare fare e he nui atu maha hononga FTTx atu te tahi atu momo katoa o hononga whatunga. Kei te tika ai te reira i roto i ngā ōhanga, me hanga te aroaro o whakataetae te whai wāhi ki te whatunga he ngawari te. Kihai titiro na roa ngā mua anake i te taha kaitango rangatōpū, a inaianei piki e whakaatu ana i te moni, me te kiritaki auau.

Āhuatanga o te hanga

Tae noa tata, hangarau FTTx whakamahia e te ngā nei kihai i whai ratou ake hanganga o nga whakatupuranga tawhito. Ko e rapu atu me te ake kamupene ki te whatunga hou i roto i nga tau tata nei. ka karanga i roto i nga take mo tenei tītohunga te te whai wāhi ki te whakawhānui i te whānuitanga o ngā ratonga, roha o whatunga hāngū e hāngai ana i runga i te muka whatu (Pon), kia rite ki te pai kia rite ki te tohatoha o Metro Itarangi, te whakaiti i te utu o ngā taputapu, te angitu o ngā maha i roto i te hanga o tenei momo o whatunga.

He momo hou o te ihirangi

Kei te hoko FTTx Internet piki haere tika ki te meka e kua tohoaki'i iwi hou ki hou momo ihirangi ki te teitei whakairoiro kounga me-teitei ataata. Ka rite ki kua i te taketake tupu whakakōkī tono o taua pūnaha hei he tipu moni i roto i ngā ratonga ataata. Kia whakawhiti te pokapū o te mahara te i multicast ki te takitahi, nui haere nga hiahia o kaiohauru tohatoha hōkaiipurangi, e rawa hohoro ka waiho ki runga ki te 100 mekapaita ia te rua ia whare.

Na kaha hoko HDTVs LCD, e hanga ana e ia e tika ana ki te whakarato i kiritaki ki te uru ki ngā hōtaka pouaka whakaata o te kounga pai atu i te mea TV kua ki te whakahere i roto i te hōputu tairitenga. Ko te taahiraa tino arorau i roto i te whanaketanga o tohunga tokomaha whakapono IP-TV. Tenei ka tukua kaiwhakamahi ki te tīpako Movies, tuku me whakaaturanga, me te te wa, ka e waiho ratou tino watea ki te mataara. Ko te aha e taea e matou te mea e te hononga papatipu FTTx xPON kua tika a tawhio te kokonga. I te kau, i tetahi peti ISP i runga i haumi i roto i te muka whatu, hei haumi mo tekau tau ki te haere mai, ia e nui te pai te utu maha nga wa i runga i. tenei anake e taea te whakamārama i te rārangi muka kia kaha hoko, me te momo o kaupapa whakamätau, tae atu auaha me te pērā i te tuuraa o te tuku kōrero tika ki te taputapu kaitango.

te tūponotanga

Hono FTTx xPON i te tau e haere mai e kore e waiho anake te kōwhiringa, hei whakapumau i te kai o te aunui, Heoi, ko te kia tiketike e taea e koe tino mohio o te hokinga mai i runga i ngā moni haumi te pūmanawa o te hanganga muka whatu. Na tino mātātoa mahi i roto i te mara o te ao hou, o whatunga tapahanga, me te FTTx mākete hangarau, taputapu, me te tahi atu wāhanga kei roto i te wähanga hoahoa, te ako, me te o te whakamātautau āta.

He aha e nga architectures rerekē?

Ka taea e te hangarau Rostelecom FTTx mahi i roto i tetahi o te maha ngā momo o architectures:

- FTTN (muka ki te Kōpuku) - te muka whatu ki te apu i te kōpuku whatunga;

- FTTC (muka ki te aukati i) - te muka unu te ki te tata, hauwhā atu whare ranei;

- FTTB (muka ki te Building) - te muka whatu tomo te whare;

- FTTH (muka ki te Home) - he muka whatu ki te apu kāinga.

Ko te rerekētanga anake i roto i te takiwā o te taura whatu ki te kāpeka kaiwhakamahi. i te tuatahi o nga mea katoa nga rongoā tuatahi e rua. Ko te tuatahi o ratou whakamahia te inaianei, engari anake rite te pūtea, me te tere tohatoha wahi kua patua huakore noa Parahi tohatoha hanganga me te muka whatu taura. Ko maheni ki te mau fifi e haere tahi i te whakatau taua tangata katoa: ko te iti kounga o ngā ratonga, takirua ki te āhuatanga motuhake o taura parahi, te rāhuitanga i runga i te maha o ngā hononga, me te tere i roto i te taura kotahi. Ko te momo tuarua - kua pai ake me te whakatinanatanga tuatahi whakarerekētia, e kore e nei i ngā tūturu whakahuatia. Whakapanga taura parahi i roto i tenei take kawea i roto anake i roto whare, na e kore e ratou i raro ki nga mea katoa o ngā āhuatanga kino, e kore te mea nui te roa o ngā rārangi. enei āhuatanga katoa kia taea ki te whakatutuki i ngā whakapainga ake i roto i te rohe o te tere e kore e whakamahi i te muka. He tika he tuku taua ki te whakamahia te hononga ko FTTx xPON. Kei te arotahi te reira i runga i nga ngā ADSL me ngā taura TV. homai te whakatinanatanga o tenei hoahoanga ratou te rave'a mo te tino penapena mā te whakapiki i te maha o ngā kaiwhakamahi hono. ka Ia o ratou e tohaina te nui hōkaiipurangi. tenei momo o ngā whatunga iti whakamahia tino maha i roto i Russia.

āhuatanga

Take e pā ana ki te whakamahinga o te taputapu mahi i runga i tenei hangarau, tei runga i te whānuitanga katoa o ngā take:

- ahakoa i reira ko te hanganga kē, rānei i mua i kore tetahi mea i whakamahia;

- ahakoa i roto i te wahi kāinga taputapu kaha, mo te e reira e etahi fakangatangata ranei;

- e hia kaiwhakamahi hiahia ki te hono ki te whatunga hou;

- he huinga o ngā āhuatanga ōrite nui.

Ka taea te whakarōpūtia ngā pūrere FTTx-kāpeka rite ki paearu rawa motuhake, kua herea reira ki te «x» wāhi. Ko te whānuitanga o ngā ratonga e patua ana e te kamupene, i runga i te maha me te momo o te atanga e whakamahi te taputapu, me te te huarahi o te whakahaere i te waka rānei. Ki te hiahia koe ki te pupuri i te hanganga tīariari, ka te kōwhiringa pai ko ki te whakamahi i ngā pūnaha FTTC / FTTB, he he optical Uplink-atanga. Ratou whakamahi tika i roto i te hinonga nui-rahi, pokapū pakihi me complexes noho, te wahi i reira ko te hanganga parahi tīariari mua. Tenei ka rapua e ia pūrere ki te tuu i te pouara FTTx.

mutunga

I roto i ngā ohaoha, te whakahaere o whatunga i runga i te hangarau muka whatu e tino tika ai ki te kukū nui o te aufauraa i kaiohauru, ranei te hanga o whenua whare hou, ka take whakahaere i runga i te whakapanga iho i te taura kei runga i te atamira hoahoa. kia whakaritea te whatunga kia he ofi ki te kaiwhakamahi rite taea te pūwāhi mutunga. Construction o ngā wāhi hou o te mea tika ki te tahi mau mai i tika i te reira ki te whare e ka watea mo e rua te timatanga me te i roto i te heke mai.
