Kodi chipangizo cha ONU ndi chiyani?

ONU (Optical Network Unit) optical network unit, ONU imagawidwa kukhala yogwira ntchito yamagetsi yamagetsi ndi gawo lopanda mawonekedwe.Nthawi zambiri, zida zokhala ndi kuwunika kwa netiweki kuphatikiza zolandila zowonera, ma transmitter optical optical transmitters, ndi amplifiers angapo mlatho amatchedwa optical node.PON imagwiritsa ntchito chingwe chimodzi cha kuwala kuti igwirizane ndi OLT, ndiyeno OLT imagwirizanitsa ndi ONU.ONU imapereka ntchito monga data, IPTV (ie televizioni yolumikizirana pa netiweki), ndi mawu (pogwiritsa ntchito IAD, mwachitsanzo, Integrated Access Device), kuzindikira kwenikweni mapulogalamu a "sewero la katatu".

Mawonekedwe

Sankhani kulandira deta yowulutsa yotumizidwa ndi OLT;

Yankhani malamulo oyambira ndi owongolera mphamvu operekedwa ndi OLT;ndi kukonza zofananira;

Sungani deta ya Ethernet ya wogwiritsa ntchito ndikuitumiza kumtunda pawindo lotumizira loperekedwa ndi OLT;

Kutsatira kwathunthu IEEE 802.3/802.3ah;

·Kulandira kukhudzika ndikokwera kwambiri mpaka -25.5dBm;

Kutumiza mphamvu mpaka -1 mpaka +4dBm;

PON imagwiritsa ntchito chingwe chimodzi cholumikizira ku OLT, kenako OLT imalumikizana ndi ONU.ONU imapereka mautumiki monga data, IPTV (ie televizioni yolumikizana), ndi mawu (pogwiritsa ntchito IAD, mwachitsanzo, Integrated Access Device), pozindikira mapulogalamu a "sewero-katatu";

· Mlingo wapamwamba kwambiri wa PON: symmetrical 10Gb / s kumtunda ndi kumunsi kwa data, mau a VoIP ndi mautumiki apakanema a IP;

·ONU “plug and play” kutengera zodziwikiratu ndi masinthidwe;

·Ntchito zapamwamba za utumiki (QoS) kutengera kulipira kwa mgwirizano wa ntchito (SLA);

Kuthekera koyang'anira kutali mothandizidwa ndi ntchito za OAM zolemera komanso zamphamvu;

· Kulandira kuwala kwamphamvu kwambiri komanso kugwiritsa ntchito mphamvu zochepa;

Thandizani ntchito ya Dying Gasp;

Kuwala kogwira ntchito

Chigawo chogwira ntchito cha optical network chimagwiritsidwa ntchito makamaka pamene maukonde atatuwa aphatikizidwa, ndipo amagwirizanitsa ndi CATV full-band RF output;mawu apamwamba a VOIP;magawo atatu osanjikiza, mwayi wopanda zingwe ndi ntchito zina, zomwe zitha kuzindikira mosavuta kupezeka kwa zida zophatikizira zamasewera atatu.

Kuwala kopanda

Passive ONU (Optical Network Unit) ndi chipangizo cham'mbali cha GEPON (Gigabit Passive Optical Network), chomwe chimagwiritsidwa ntchito kuthetsa ntchito zotumizidwa kuchokera ku OLT (Optical Line Terminal) kudzera pa EPON (Passive Optical Network).Kugwirizana ndi OLT, ONU ikhoza kupereka mautumiki osiyanasiyana a Broadband kwa ogwiritsa ntchito olumikizidwa.Monga kusewera pa intaneti, VoIP, HDTV, VideoConference ndi ntchito zina.ONU, monga chipangizo cham'mbali cha ntchito za FTTx, ndi chipangizo chapamwamba cha bandwidth ndi chotsika mtengo chothandizira kusintha kuchokera ku "nyengo yamkuwa" kupita ku "optical fiber era".Monga yankho lomaliza la ogwiritsa ntchito mawaya, GEPON ONU itenga gawo lalikulu pakumanga kwa netiweki kwa NGN (Next Generation Network) mtsogolomo.

UTStarcom ONU 1001i ndi zida zotsika mtengo zomwe zimagwiritsidwa ntchito pamakina a GEPON.Imapangidwira ogwiritsa ntchito kunyumba ndi ogwiritsa ntchito a SOHO, ndipo imapereka kulumikizana kwa gigabit broadband kwa zipata za ogwiritsa ntchito ndi / kapena ma PC.ONU 1001i imapereka doko limodzi la 1000Base-TEthernet la data ndi IPTV makanema.ONU1001i ikhoza kukhazikitsidwa patali ndikuyendetsedwa ndi UTStarcom BBS mndandanda wa optical line terminal (OLT).

ntchito

Kumtunda kwa ONU 1001i kumalumikizidwa ku ofesi yapakati (CO) kudzera pa doko la GEPON, ndipo kutsika kwapansi ndi kwa ogwiritsa ntchito payekha kapena ogwiritsa ntchito SOHO kuti apereke 1 Gigabit Ethernet network port.Monga yankho lamtsogolo la FTTx, ONU 1001i imapereka mau amphamvu, deta yothamanga kwambiri ndi mavidiyo kudzera mu GEPON ya fiber single.
