Mune yedhijitari nguva yekupatsanura kuwanda kwekukurukurirana system, kuti inyatso kupatsanura nguva slot masaini, iyo yekupedzisira yekutumira inofanirwa kupa chiratidzo chekutanga chega yega furemu, uye maitiro ekuona nekuwana iyi chiratidzo pamagumo ekugamuchira anonzi furemu synchronization.Kune marudzi maviri eiyo furemu kuwiriranisa: kutanga-kumisa nzira yekuyananisa uye isa yakakosha yekuyananisa kodhi nzira yeboka.
Kutanga-kumisa nzira yekubatanidza:Boka rekodhi pacharo rine ruzivo rwayo rwekuunganidza nekushandisa yakakosha kodhi element encoding mutemo pakupera kwekutumira.
Kuisa yakakosha yekuyananisa kodhi nzira yeboka:Zvinoreva kuisa akati wandei macode ekuwiriranisa furemu kuwiriranisa mune inofambiswa chiratidzo kutevedzana.
Kune kunyanya marudzi maviri epakati pekuisa uye kuisa interval. Kuiswa kwepakati, kunozivikanwawo sekunge kwakabatana kuisa, kunoda kuti furemu yekubatanidza yakakosha block ine yakanakisa autocorrelation maitiro. Inowanzo shandiswa furemu yekubatanidza kodhi boka ndiyo Barker kodhi. Interval kupinza. Iyo inozivikanwawo sekuisirwa kuisirwa, yakapusa periodic cyclic kutevedzana kunowanzo shandiswa seiyo furemu yekubatanidza kodhi, uye inopinzwa zvakafanana murukova rweruzivo.
Chikonzero nei iyo data link layer ichibatanidza mabits mumafuremu uye nekuaendesa ndechekuti kana chikanganiso chikaitika, furemu chete ine zvikanganiso inogona kuendeswazve, uye hazvifanirwe kuendesa zvakare data rese, nekudaro kuvandudza kushanda. Checksums inowanzoverengerwa kune imwe neimwe furemu. Kana furemu yasvika kwainoenda, cheki inoverengerwa zvakare, uye kana yakasiyana neyekutanga cheki, kukanganisa kunogona kuonekwa.
Izvo zviri pamusoro ndiyo tsananguro yeruzivo ye "OSI-Data Link Layer-Frame Synchronization Function" 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.
OLTclass: 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 nesu kune chero rudzi rwekubvunza.
