LM240TUW5 wapawiri-mode ONU/ONT imagwira ntchito mu FTTH/FTTO, kuti ipereke chithandizo cha data potengera netiweki ya EPON/GPON.LM240TUW5 imatha kuphatikizira ntchito zopanda zingwe ndikukwaniritsa miyezo yaukadaulo ya 802.11 a/b/g/n/ac, imathandiziranso ma 2.4GHz & 5GHz opanda zingwe.Iwo ali ndi makhalidwe amphamvu olowerera mphamvu ndi lonse Kuphunzira.Ikhoza kupatsa ogwiritsa ntchito chitetezo chokwanira chotumizira deta.Ndipo imapereka ma TV otsika mtengo omwe ali ndi 1 CATV Port.
Ndi liwiro lofikira 1200Mbps, 4-Port XPON ONT imatha kupatsa ogwiritsa ntchito mafunde osalala pa intaneti, kuyimba foni pa intaneti, ndi masewera apa intaneti.Kuphatikiza apo, potengera mlongoti wakunja wa Omni-directional, LM240TUW5 imatha kukulitsa ma waya opanda zingwe & kukhudzika, zomwe zimakupatsani mwayi wolandila ma siginecha opanda zingwe pakona yakutali kwambiri yanyumba yanu kapena ofesi.Mutha kulumikizananso ndi TV ndikulemeretsa moyo wanu.
ONU (Optical Network Unit) ndi chipangizo chotumizira mauthenga chogwiritsidwa ntchito mu fiber optic communication system ndi ntchito ziwiri za "kutumiza" ndi "kulandira".Ndi chipangizo chomwe chili mu network ya optical yomwe imagwirizanitsa zingwe za kuwala kwa zipangizo za ogwiritsa ntchito.Kuyankhulana kwa Fiber optic ndi teknoloji yolankhulana yomwe imagwiritsa ntchito kuwala monga chizindikiro cha Bellman, ONU ndi imodzi mwa zipangizo zofunika kwambiri zoyankhulirana ndi mauthenga.Poyerekeza ndi zida zamtundu wanthawi zonse, ONU ili ndi mikhalidwe iwiri:
Choyamba, pokhudzana ndi kulumikizidwa kwakuthupi, ONU imagwiritsa ntchito zingwe za fiber optic m'malo mwa zingwe zama network.Chifukwa chingwe cha fiber optic chimakhala ndi liwiro lalikulu lotumizira, mphamvu yotumizira deta, komanso mtunda wautali wotumizira, ndi yoyenera kwambiri kufalitsa deta yothamanga kwambiri komanso yothamanga kwambiri.
Chachiwiri, ONU imagwiritsa ntchito luso lapadera la TDMA (Time Division Multiple Access) kuti lipereke deta yodalirika kwa ogwiritsa ntchito osiyanasiyana nthawi zosiyanasiyana kuti zitsimikizire kukhazikika ndi chitetezo cha kutumiza deta.
Zofunikira
Kukula kwa United Nations kwathandizira kwambiri chitukuko cha Broadband.Scope nthawi zambiri imakhala ndi zinthu zitatu izi:
1. Pezani m'lifupi mwa nyumbayo
Kuonjezera apo, zosowa za digito za mabanja amakono zawonjezeka ndipo pakufunika kutumiza zambiri ku malo a kunyumba, zomwe zimafuna chithandizo chachangu komanso chothandiza.M'mbuyomu, ukadaulo wa ADSL unali ndi malire potengera liwiro lotumizira, koma UN imagwiritsa ntchito ma fiber optics kufikira ogwiritsa ntchito.Imathandizira kuthamanga kwambiri kwa mazana a megabits, zomwe zidzakwaniritse zosowa za kutumiza deta yambiri.
2. Kufika kumidzi
Kumadera akumidzi, kupezeka kwa mabroadband achikhalidwe kumakhala kovuta kukwaniritsa zosowa za ogwiritsa ntchito chifukwa cha kuchepa kwa zomangamanga.Bungwe la United Nations limagwiritsa ntchito ukadaulo wa fiber optic womwe ungathe kutumiza deta pamtunda wautali, kupereka chithandizo chachangu kumadera akumidzi ndikuthandizira kwambiri zomangamanga za United Nations.
3. Kapangidwe ka bizinesi
Pankhani ya bizinesi, potumiza deta kumadera osiyanasiyana, ONU imagwiritsa ntchito njira zosiyanasiyana komanso zosiyana siyana, zomwe sizimangowonjezera machitidwe a intaneti, komanso zimathandizira chitetezo cha kufalitsa deta.kampani.
m'tsogolo
Pakalipano, ndi chitukuko cha 5G, cloud computing ndi matekinoloje ena, maukonde achikhalidwe sangathe kukwaniritsa zomwe zikuwonjezeka.Mosiyana ndi izi, ukadaulo wa fiber optic uli ndi zabwino zotumizira mwachangu, kukhazikika kwabwino komanso bandwidth yayikulu.Chifukwa chake, ONU ngati chipangizo chokulirapo ili ndi kuthekera kwakukulu kwachitukuko.M'tsogolomu, kafukufuku wina akhoza kuchitidwa m'madera otsatirawa:
1. Bwino Sinthani luso lamakono kuti mupititse patsogolo hardware ndi kutsitsa liwiro
Chitani kafukufuku wopitilira paukadaulo wofananira, kuyang'ana kwambiri pakuwongolera kukhazikika kwa Hardware, kukulitsa liwiro lotumizira pochepetsa zida zowononga mphamvu, ndikuchepetsa kwambiri ndalama zotumizira ma netiweki.
2. Wonjezerani kuchuluka kwa kagwiritsidwe ntchito ndi kulimbikitsa njira zodziwitsira anthu
Ntchito za UN sizimangokhala kunyumba ndi mabizinesi.M'tsogolomu, madera ogwiritsira ntchito akhoza kukulitsidwa, ndipo ndondomeko ya chidziwitso cha chikhalidwe cha anthu ingagwiritsidwe ntchito m'madera monga kumanga mzinda wanzeru ndikumanga intaneti ya Zinthu kuti ipititse patsogolo chidziwitso.
3. Limbikitsani chitetezo cha intaneti ndikuwongolera chitetezo cha ogwiritsa ntchito
Pamene umbava wa pa intaneti umakhala wosiyanasiyana komanso wovuta, chitetezo chapaintaneti chiyenera kulimbikitsidwa kuti zitsimikizire chitetezo chokwanira komanso chokwanira pakutumiza kwa data kwa ogwiritsa ntchito.
