Iyo yemuviri dhizaini iri pazasi peiyo OSI modhi, uye basa rayo guru ndere kushandisa svikiro rekutapurirana kuti ripe chinongedzo chemuviri kune data link layer kufambisa bit hova. Iyo yemuviri dhizaini inotsanangura kuti tambo yakabatana sei kunetiweki kadhi, uye ndeipi tekinoroji yekufambisa inoda kushandiswa kutumira data patambo, uye inotsanangura nzira yekuwana iyo yekumusoro layer (data link layer).
Kazhinji, michina ine kumwe kugadzirisa data uye kutumira uye kugamuchira kugona kunonzi data terminal midziyo (DTE), uye midziyo iri pakati peDTE neyekufambisa yekufambisa inonzi data circuit terminating equipment (DCE). DCE inopa chiratidzo chekushandura uye encoding mabasa pakati peDTE uye yekufambisa svikiro, uye ine basa rekumisikidza, kuchengetedza uye kuburitsa zvinongedzo zvemuviri. Nekuti iyo DCE iri pakati peDTE neyekufambisira svikiro, panguva yekutaurirana, DCE inoendesa iyo data yeDTE kune yekufambisa svikiro kune rimwe divi, uye kune rimwe divi, inoda kufambisa kadiki rwizi rwakagamuchirwa kubva svikiro rekutumira kune DTE zvakatevedzana. , DCE inoda kufambiswa kweruzivo rwe data uye ruzivo rwekutonga, uye inoda kushanda mune yakakwira dhigirii yekubatana, saka zvakafanira kuumba iyo interface zviyero zveDTE neDCE, zviyero izvi zvimiro zvemuviri.
Uye iyi chiyero inotsanangura maitiro mana emuviri layer:
1. Mechanical maitiro: Tsanangura maitiro ekubatana kwemuviri, tsanangura zvinotsanangurwa, chimiro chechimiro, nhamba yevatungamiri, nhamba uye kurongeka kwepini inoshandiswa mukubatana kwemuviri, nezvimwewo.
2. Mamiriro emagetsi: Kana uchitsanangura kutapurirana kwebhinari bits, iyo voltage range, impedance matching, transmission rate uye kureba kwechiratidzo pamutsara, nezvimwewo.
3. Hunhu hunoshanda: ratidza zvinorehwa nemwero weimwe nhanho pane imwe mutsara zvinorevei, uye chinangwa chemutsara wechiratidzo icho chimiro chisingaoneki.
4. Maitiro maitiro (maitiro maitiro): tsanangura maitiro ekushanda uye hukama hwenguva yedunhu rega rega remuviri
Izvo zviri pamusoro ndiyo tsananguro yeruzivo ye "OSI-Physical Layer Characteristics" yakaunzwa neShenzhen HDV photoelectric Technology Co., Ltd. Zvigadzirwa zvekutaurirana zvinogadzirwa nekavha yekambani:
Zvikamu zvemodule: optical fiber modules, Ethernet modules, Optical fiber transceiver modules, Optical fiber access modules, SSFP Optical modules,uyeSFP optical fibers, nezvimwewo.
ONUchikamu: EPON ONU, AC ONU, Optical fiber ONU, CATV ONU, GPON ONU, XPON ONU, nezvimwewo.
OLTkirasi: kuchinja OLT, GPON OLT, EPON OLT, kutauriranaOLT, nezvimwewo.
Izvo zviri pamusoro module zvigadzirwa zvinogona kupa rutsigiro kune akasiyana network mamiriro. Nyanzvi uye yakasimba R&D timu inogona kubatsira vatengi nenyaya dzehunyanzvi, uye timu inofunga uye ine hunyanzvi bhizinesi inogona kubatsira vatengi kuwana masevhisi emhando yepamusoro panguva yepamberi yekubvunzana uye mushure mekugadzira basa. Tinokugamuchirai taura nesunokutichero rudzi rwekubvunza.
