AON vs PON Networks: Sarudzo dzeFiber-to-the-Home FTTH Systems

Fiber to the Home (FTTH) inzira inoisa fiber optics kubva panzvimbo iri pakati zvakananga muzvivakwa zvakaita sedzimba nemafurati. Kuiswa kweFTTH kwafambira mberi zvikuru vasati vatanga kushandisa fiber optics panzvimbo pemhangura kuti vawane internet yakawanda.

Kune nzira mbiri huru dzekushandisa network yeFTTH inomhanya zvikuru:network dzinoshanda dzemaziso(AON) uye kungoita zvinhu zvisina basanetwork dze optical(PON).

Saka network dzeAON nePON: musiyano uripi?

Chii chinonzi network yeAON?

AON ihurongwa hwe network hunobatanidza ma "point-to-point" umo munhu wese anenge aine fiber optic line yake inogumira pa "optical concentrator". Network yeAON inosanganisira zvishandiso zvemagetsi zvakaita se "routers" kana "switching aggregators" kuti itarisire kugoverwa kwemasaini uye ma "directional signaling" kune vatengi vakasiyana.

Maswichi anobatidzwa nekudzima nenzira dzakasiyana-siyana kuti atungamirire masaini anopinda neanobuda kunzvimbo dzakakodzera. Kuvimba kwetekinoroji yeEthernet kunoita kuti kushanda pamwe chete pakati pevanopa ruzivo kuve nyore. Vanyoreri vanogona kusarudza hardware inopa data rakakodzera uye kuwedzera sezvo zvavanoda zvichiwedzera pasina kufanira kugadzirisa network. Zvisinei, ma network eAON anoda kanenge switch aggregator imwe chete pamunhu mumwe nemumwe.

Chii chinonzi network yePON?

Kusiyana neAON networks, PON inetwork architecture inoshandisa passive splitters kuparadzanisa nekuunganidza optical signals. Fiber splitters inobvumira PON network kushandira vanhu vakawanda vanonyoresa mufiber imwe chete pasina chikonzero chekuisa fiber dzakasiyana pakati pehub nemushandisi wekupedzisira.

Sezvinoratidzwa nezita racho, maPON network haana michina yekuchinja ine mota uye ma fiber bundles ekugovana zvikamu zve network. Midziyo inoshanda inongodiwa chete panobva chiratidzo uye pamagumo anogamuchira.

Mune network yePON yakajairika, PLC splitter ndiyo inonyanya kushandiswa. Mapombi efiber optic anosanganisa masaini akawanda e optical kuita output imwe chete, kana kuti mapombi e fiber optic anotora optical input imwe chete oigovera kune akawanda ma output. Mapombi aya ePON anoenda kumativi maviri. Kuti zvive pachena, masaini e fiber optic anogona kutumirwa pasi kubva ku central office kuti aendeswe kune vese vanyoresa. Masaini kubva kune vanyoresa anogona kutumirwa kumusoro uye kubatanidzwa kuita fiber imwe chete kuti itaurirane ne central office.

AON vs PON Networks: Kusiyana uye Sarudzo

Manetwork ePON neAON anoumba musimboti we fiber optic weFTTH system, zvichibvumira vanhu nemabhizinesi kushandisa internet. Usati wasarudza PON kana AON, zvakakosha kunzwisisa mutsauko uripo pakati pawo.

Kuparadzirwa kweChiratidzo

Kana zvasvika kune ma network eAON nePON, musiyano mukuru pakati pavo ndewekuti chiratidzo che optical chinogoverwa sei kune mutengi wega wega mu FTTH system. Mu system yeAON, vanyoreri vane ma bundles akatsaurirwa e fiber, izvo zvinovabvumira kuwana bandwidth imwechete, pane imwe inogovaniswa. Mu network yePON, vanyoreri vanogovana chikamu che fiber bundle ye network muPON. Nekuda kweizvozvo, vanhu vanoshandisa PON vanogonawo kuona kuti system yavo inononoka nekuti vashandisi vese vane bandwidth imwe chete. Kana dambudziko rikaitika mukati me PON system, zvinogona kuoma kuwana kwakabva dambudziko.

Mari

Mari yakawanda inobhadharwa ne network ndeyekushandisa magetsi nekuchengetedza michina. PON inoshandisa michina isingashande inoda kugadziriswa kushoma uye isina magetsi kupfuura network yeAON, inova network inoshanda. Saka PON yakachipa pane AON.

Kureba uye Mashandisirwo eKufukidza

AON inogona kufukidza daro rinosvika makiromita makumi mapfumbamwe, nepo PON inowanzo ganhwa netambo dze fiber optic dzinosvika makiromita makumi maviri. Izvi zvinoreva kuti vashandisi vePON vanofanira kunge vari pedyo nenzvimbo yechiratidzo chekutanga.

Pamusoro pezvo, kana zvakabatana nechirongwa kana sevhisi yakati, zvimwe zvinhu zvakawanda zvinofanira kufungwa nezvazvo. Semuenzaniso, kana masevhisi eRF nemavhidhiyo achizoshandiswa, saka PON ndiyo mhinduro chete inoshanda. Zvisinei, kana masevhisi ese akavakirwa paInternet Protocol, saka PON kana AON zvingave zvakakodzera. Kana daro refu richibatanidzwa uye kupa simba nekutonhodza zvikamu zvinoshanda mumunda kunogona kuva dambudziko, saka PON inogona kunge iri sarudzo yakanakisa. Kana, kana mutengi ari kutariswa ari wekutengesa kana purojekiti ichisanganisira dzimba dzakawanda, saka network yeAON inogona kunge yakakodzera.

AON vs. PON Networks: Ndeipi FTTH yaunoda?

Pakusarudza pakati pePON kana AON, zvakakosha kufunga nezvemasevhisi api achapihwa kuburikidza nenetwork, topology yenetwork yese, uye kuti vatengi vakuru ndivanaani. Vashandi vazhinji vakaisa musanganiswa wemanetwork ese ari maviri mumamiriro akasiyana. Zvisinei, sezvo kudiwa kwekubatana kwenetwork uye scalability kuri kuramba kuchikura, magadzirirwo enetwork ari kubvumira chero fiber kuti ishandiswe zvakasiyana muPON kana AON applications kuti isangane nezvinodiwa zveramangwana.
