Parizvino, maererano neoptical fiber access network tekinoroji, narrowband kuwana zvishoma nezvishoma inotsiviwa nebroadband kuwana, uye pakupedzisira fiber imba inowanikwa. Iyo Broadband optical fiber yetiweki yekuwana inova isingadzivisike, uye tekinoroji yePON ichava iyo tekinoroji hotspot yebroadband yekuwana network mune ramangwana nekuda kweayo akawanda-sevhisi, yakaderera mari uye kugadzirisa nyore.
Chii chinonzi fiber access network?
Iyo optical fiber access network inoreva network yekupinda umo iyo yekufambisa svikiro ndeye optical fiber. Optical fiber yekuwana network inogona kukamurwa zvine mutsindo kuita mapoka maviri: anoshanda optical network (AON, Active Optical Network) uye passive optical network (PON, Passive Optical Network).
Active optical network inogona kukamurwa kuita AON zvichibva paSDH neAON zvichibva paPDH;
Passive optical network inogona kukamurwa kuita narrowband PON uye Broadband PON.
Ndeipi basa rinoitwa netiweki yekuwana mukuvaka network?
Iyo ruzivo network inoumbwa neiyo core backbone network, metropolitan area network, network yekuwana, uye yevatengi nzvimbo network. Iyo yekuwana network iri pabhiriji reiyo metropolitan area network / backbone network.
Parizvino, sainzi uye tekinoroji zviri kufambira mberi nekusvetuka uye miganhu, uye nhamba huru yemafaira emagetsi anogara achigadzirwa. Nekudyidzana kwepasi rose kwehupfumi uye nekukasira kweruzivo rwemagariro, iyo Internet yakave yakakurumbira, masevhisi edata akakura nechisimba, uye mhando dzemasevhisi ekufonera dzakaramba dzichiwedzera. Rudzi rwebhizimisi. Iyo narrowband yekuwana network yave bhodhoro rinorambidza kuvandudzwa kwenetwork kune Broadband. Musika wekuwana network une hukuru hukuru, uye matekinoroji matsva anogara achibuda kuti asangane nezvinodiwa nevashandisi. Iyo yekuwana network ndiyo inotariswa uye kiyi yekusimudzira ruzivo rwenyika. Network yekuwana tekinoroji yave iyo yekutarisa uye yekuisa hotspot yemasangano ekutsvagisa, vatengesi vekutaurirana, makambani ekufonera uye madhipatimendi anoshanda.
Zvakanakira zvePON
1. Inogona kupa pachena Broadband uye yakaderera-mutengo kutapurirana kugona.
2. Kuenzaniswa neanoshanda optical network, kuiswa kwayo, kutumira uye kugadzirisa mari yekushanda yakaderera, uye hurongwa hunovimbika uye hwakagadzikana, saka network yekuwana iri kushandisa nhamba huru yePON systems.
3. Nokuti PON inotora nzira-ku-multipoint access mode, mari yezvivakwa zvekuisa optical fiber pakati pehofisi yepakati nevashandisi inotakurwa nevashandisi, izvo zvinogona kuwedzera kudzoka kwekudyara mukuvaka network. Kuenzaniswa nenzira yekugadzirisa kuguma-kusvika-kumagumo optical fiber kune umwe neumwe mushandisi, huwandu hwePON midziyo inovandudza masevhisi enhamba imwechete yevatengi idiki uye inotora nzvimbo shoma muhofisi yepakati.
4. PON inotsigira ese ari maviri masevhisi echinyakare (chinyakare runhare service POTS, analog TV) uye Broadband masevhisi (IP voice transmission, IPTV, broadband Internet access, etc.).
5.PON inotsigira vese vashandisi vekugara (vachishandisa POTS, analogi TV uye data masevhisi) uye vazhinji vashandisi vekutengesa (vachishandisa T1 / E1 uye Ethernet masevhisi) kugovera network yekuwana (kusanganisira iyo yemuviri layer uye protocol layer) pasina kushandisa nzira dzakasiyana. Kuwana kunetiweki kunopa masevhisi kwavari, nekudaro kudzikisa huwandu hweakapararira kuwana network.
