Munyika yanhasi inomhanya-mhanya, uko kubatana kunobata basa rakakosha mune yega yega yehupenyu hwedu, zvakakosha kuti tive nemhinduro dzakavimbika uye dzinoshanda dzetiweki kuzadzisa zvinodikanwa zvakasiyana zvemhuri. Nekuuya kwehunyanzvi hwepamusoro seCATV ONUs (Optical Network Units), tiri kupupurira kusimukira mukubatana kwemba. Mune ino blog positi, tichapinda munyika inonakidza yeCATV ONU, kugona kwayo, uye maitiro ainogona kushandura kubatana kwepamba.
Yakasanganiswa neaviri-fiber matatu-wave tekinoroji:
CATV ONUyakavakirwa pambiri-fiber uye katatu-wave tekinoroji kuti ive yakagadzikana, yakakwirira-kumhanya yeInternet yekubatanidza. Iyi tekinoroji yekucheka-kumucheto inosanganisa simba refiber optics kuendesa data, izwi uye vhidhiyo masaini panguva imwe chete, ichipa vashandisi ruzivo rwepamhepo rusina musono, rusingapindiki.
Nhepfenyuro neTerevhizheni FTTH Business Comprehensive Business Committee:
Chimwe chezvinhu zvikuru zveCATV ONU ibhodhi rebasa rayo rakasanganiswa, iro rinogona kubatanidza redhiyo neterevhizheni FTTH (fiber kumba) masevhisi. Nekubatanidza uku, vashandisi vanogona kunakidzwa nemhando dzakasiyana dzeredhiyo neTV kubva mukunyaradza kwedzimba dzavo, vachivandudza ruzivo rwavo rwevaraidzo. Nekushandisa simba rekugamuchira optical, CATV ONU inova nechokwadi chekugamuchira chiratidzo chisina mhosva uye kutapurirana kupfuura echinyakare mhangura-yakavakirwa mhinduro.
Wireless WiFi uye CATV mwenje yekugamuchira basa:
CATV ONU inosanganisa isina waya yeWiFi uye CATV Optical yekugamuchira masimba kuti ipfuure echinyakare yekubatanidza mhinduro. Kubatanidzwa uku kunoita kuti vashandisi vagadzirise nyore nyore imba yeLAN (Local Area Network). CATV ONU inopa 4 Ethernet interfaces uye isina waya yeWiFi yekubatanidza, ichibvumira akawanda maturusi kuti abatanidze uye agogovana zviwanikwa panguva imwe chete. Kunyangwe kushambadzira mafirimu, mitambo yepamhepo, kana kushanda uchibva kumba, iyo LAN yekumba yakagadzirwa neCATV ONU inogonesa kubatana uye kugovana data mukati memba.
Tsigira Internet uye tambo TV kutepfenyura uye terevhizheni masevhisi:
Kuburikidza neCATV ONU, vashandisi havangogone kunakidzwa nekusavhiringidzwa masevhisi eInternet, asiwo kuwana yakakura CATV kutepfenyura uye zveterevhizheni. Nekushandisa Ethernet interface neWiFi isina waya, CATV ONU inogonesa vashandisi kutarisa paInternet nekumhanya kwemheni pamusoro peEPON (Ethernet Passive Optical Network). Panguva imwecheteyo, iyo CATV Optical receiver inogamuchira madhijitari TV masaini kuti ive nechokwadi chekuti vashandisi vanowana yemhando yepamusoro, yepamusoro-tsanangudzo yeTV ruzivo. Iko kusanganiswa kweInternet uye tambo dzeTV masevhisi anonyatsoziva chiono chefiber-to-the-imba (FTTH), ichipa vashandisi mhinduro yakazara yekubatanidza.
Muchidimbu:
Muchidimbu,CATV ONUtekinoroji yakachinja zvachose kubatana kwepamba nekubatanidza mbiri-fiber uye matatu-wave tekinoroji, yakasanganiswa masevhisi mabhodhi, isina waya WiFi uye CATV optical reception mabasa. Ichi chitsva chinovhura nzira yekubatanidza isina musono uye kugovana mukati memba, ichipa isina kukanganiswa Internet sevhisi uye yakapfuma tambo kutepfenyura uye zveterevhizheni. NeCATV ONU, mhuri dzinogona kugashira ramangwana rekubatana uye kunakidzwa neInternet yekumhanyisa, terevhizheni yepamusoro-tsanangudzo uye zviitiko zvisingaenzaniswi zvevaraidzo.
