Optical network terminal (inowanzozivikanwa seOptical katsi kana Optical modem), inoreva kutapurirana kuburikidza nee fiber medium, iyo optical chiratidzo modulation uye demodulation kune mamwe masaini masaini etiweki michina. Chishandiso cheLightcat chinoshanda sechishandiso chekutumira chekuendesa kune yakakura nharaunda nharaunda network, metropolitan nharaunda network uye yakafara nzvimbo network. Kusiyana ne-optical transceiver, transceiver optical inongogamuchira uye inobudisa chiedza, uye haisanganisi kutendeuka kweprotocol.
A Modem chishandiso chemagetsi chinogadzirisa siginecha yedhijitari kune analog siginecha yekufambisa, uye inodhiza iyo yakagamuchirwa analog siginecha kuti iwane chiratidzo chedhijitari. Chinangwa chayo ndechekugadzira chiratidzo cheanalog chinogona kufambiswa zviri nyore uye kudzoreredza iyo yekutanga digital chiratidzo nekudhikodha. Zvichienderana nekushandiswa, iyo MODEM inogona kushandisa nzira dzakasiyana kuendesa masaini eanalog, senge fiber optics, RF radio, kana mitsara yerunhare.
Mamodemu enhare anoshandisa bhendi redhiyo yetambo yenharembozha yekutaurirana data ndiwo most inowanzosangana modem. Muchirungu chinotaurwa, vanhu vazhinji vanotaura kumodemu yefoni se "katsi" kana "mashiripiti" zvichibva pane syllable yekutanga yemataurirwo echiRungu.
Mamwe mamodemu akajairwa anosanganisira tambo modem yeBroadband data yekuwana, ADSL modem, uye fiber modem. A digitaalinen nhare mbozha chaizvoizvo wireless modem. Michina yemazuva ano yekufambisa nhare yakagadzirirwa kuendesa huwandu hwakawanda hweruzivo pamusoro pemarefu marefu pane akasiyana midhiya, saka zvakare yakavakirwa pakushanda kwemodem. Microwave modem inogona kushandiswa pamamiriyoni emabhiti pasekondi. Iyo optical modem inoshandisa optical fiber sezvo iyo yekufambisa svikiro inogona kusvika kupfuura makumi eGbps, ikozvino ndiyo musimboti wekutumira telecommunication Passive optical network (Passive optical network), inozivikanwawo se passive optical fiber network, imhando ye optical fiber kutaurirana. network, iyo inoratidzwa nekushaikwa kwemagetsi kupedzisa kugadzirwa kwechiratidzo, kungofanana negirazi kumba, haidi magetsi kuratidza mufananidzo, kunze kweiyo terminal michina inoda kushandisa magetsi, iyo node dziri pakati dzakagadzirwa. yakapfava uye diki fiber optic zvikamu.
Zvinoenderana nepfungwa yeNew Generation Network (NGN), telecommunication network inogona kukamurwa kuita zvikamu zviviri: core network uye access network. Iyo yepakati network yakaenzana neyechinyakare relay uye kureba-kure mitsetse. Network yekupinda ine ring yefiber optic cables. Mabasa epakati network uye network yekuwana akasiyana, uye mafomu avo ekutapurirana akasiyana. Naizvozvo, maPON maapplication anogona kukamurwa kuita mhando mbiri: PON yepakati network uye PON yekuwana network. Iyo yekutanga inonyanya kuenderana neWDM, uye iyo yekupedzisira inoshandisa ese ari maviri optical diverter uye WDM zvikamu.
Ruzivo rwuri pamusoro itsananguro pfupi pamusoro peiyo optical network terminal yakaunzwa neShenzhen HDV Phoelectron Technology LTD., inova mugadziri ane hunyanzvi mumidziyo yekutaurirana network sezvigadzirwa zvayo zvikuru. Midziyo yavo yakabatana ine hukama ne:oltonu/ akangwaraonu/ aconu/ fiberonu/ catvonu/ gpononu/xpononu/ oltmudziyo/oltchinja/gponolt/ eponoltuye zvichingodaro, gamuchirai vashandisi kuti vauye kune chigadzirwa kubvunza.
