Nhoroondo ye XPON Technology Overview
XPON tekinoroji yekuwana Broadband yakavakirwa paPassive Optical Network (PON). Iyo inowana yakakura-kumhanya uye yakakura-inogonesa data kutapurirana kuburikidza ne-single-fiber bidirectional kutapurirana. XPON tekinoroji inoshandisa iyo passive yekufambisa maitiro eiyo optical masaini kugovera optical masaini kune akawanda vashandisi, nekudaro vachiona kugovana kwe mashoma network zviwanikwa.
XPON system chimiro
Iyo XPON system inonyanya kuve nezvikamu zvitatu: optical line terminal (OLT), optical network unit (ONU) uye passive optical splitter (Splitter). Iyo OLT iri pahofisi yepakati peanoshanda uye ine basa rekupa network-parutivi nzvimbo dzekubatanidza uye kufambisa data hova kune epamusoro-layer network senge metropolitan area network. Iyo ONU iri pamagumo evashandisi, ichipa vashandisi kuwana network uye kuona kutendeuka uye kugadzirisa kwedata data. Passive optical splitters inogovera masaini masaini kune akawandaONUs kuwana network coverage.

XPON yekufambisa tekinoroji
XPON inoshandisa tekinoroji yekuparadzanisa nguva yekuwedzera (TDM) kuti iwane kutapurirana kwedata. MuTekinoroji yeTDM, nzvimbo dzakasiyana dzenguva (Nguva Slots) dzakakamurwa pakati peOLT neONU kuona bidirectional kuendesa data. Kunyanya, iyoOLTinogovera data kune akasiyana maONU zvichienderana nenguva inotsvedza munzira yekukwira kumusoro, uye inotepfenyura data kune ese maONU munzira yakadzika. Iyo ONU inosarudza kugamuchira kana kutumira data zvinoenderana nenguva yekuzivikanwa.

XPON data encapsulation uye kuongorora
Muchirongwa che XPON, data encapsulation inoreva maitiro ekuwedzera ruzivo rwakadai semisoro uye matrailer kumayuniti edata anofambiswa pakati peOLT neONU. Ruzivo urwu runoshandiswa kuona mhando, kwainoenda uye humwe hunhu hweiyo data unit kuitira kuti iyo inogashira yekupedzisira igone kuburitsa uye kugadzirisa iyo data. Data parsing ndiyo nzira iyo iyo yekupedzisira yekugamuchira inodzoreredza iyo data kune yayo yekutanga fomati zvichienderana neruzivo rwe encapsulation.
XPON data transmission process
Muiyo XPON system, iyo data yekufambisa maitiro inonyanya kusanganisira anotevera matanho:
1. Iyo OLT inoputira data muzviratidzo zvemaziso uye inotumira kune passive optical splitter kuburikidza netambo yemaziso.
2. Iyo passive optical splitter inogovera chiratidzo chemaziso kune inoenderana ONU.
3. Mushure mekugamuchira chiratidzo chemaziso, ONU inoita optical-to-electrical kutendeuka uye inobvisa data.
4. ONU inosarudza nzvimbo yedhesi zvichienderana nemashoko ari mu data encapsulation, uye inotumira data kune chigadziro chinoenderana kana mushandisi.
5. Chigadzirwa chekugamuchira kana mushandisi anoongorora uye anogadzirisa iyo data mushure mekuigamuchira.
XPON's kuchengetedza michina
Matambudziko ekuchengetedza akatarisana neXPON anonyanya kusanganisira kupinda zvisiri pamutemo, kurwiswa kwakashata uye kuteedzera data. Kuti ugadzirise matambudziko aya, iyo XPON system inotora nzira dzakasiyana dzekuchengetedza:
1. Nzira yekusimbisa: Ita chiziviso chechokwadi paONU kuti uone kuti vashandisi vepamutemo chete vanogona kuwana network.
2. Encryption mechanism: Encrypt data yakafambiswa kudzivirira data kubva pakunzwa kana kukanganiswa.
3. Kupinda kwekutonga: Dzivirira kodzero yevashandisi yekuwana kudzivirira vashandisi zvisiri pamutemo kubva kushandisa zvisizvo zviwanikwa zvetiweki.
4. Kuongorora uye kutyisa: Tarisa mamiriro etiweki munguva chaiyo, alarm munguva apo mamiriro asina kunaka anowanikwa, uye tora matanho ekuchengetedza anoenderana.
Kushandiswa kweXPON mune network yekumba
XPON tekinoroji ine tarisiro yakakura yekushandisa mumatineti epamba. Chekutanga pane zvese, XPON inogona kuwana yakakwirira-kumhanya yeInternet kuti isangane nezvinodiwa zvevashandisi vekumba zvekumhanya kwetiweki; chechipiri, XPON haidi wiring yemukati, iyo inoderedza kuisirwa nekugadzirisa mari yemagetsi epamba; pakupedzisira, XPON inogona kuona kubatanidzwa kweakawanda network, kubatanidza nhare, maTV nemakomputa. Iyo network inosanganiswa mune imwecheteyo network kufambisa kushandiswa kwevashandisi uye manejimendi.
