Kwinkqubo yedijithali yolwahlulo lwe-multiplexing yonxibelelwano, ukwenzela ukwahlula ngokuchanekileyo iimpawu ze-slot yexesha, isiphelo sokuthumela kufuneka sinikeze uphawu lokuqala lwesakhelo ngasinye, kunye nenkqubo yokufumanisa nokufumana olu phawu ekupheleni kokufumana kubizwa ngokuba yi-synchronization yesakhelo.Kukho iindidi ezimbini zongqamaniso lwesakhelo: indlela yokuqalisa-yekisa ungqamaniso kwaye ufake indlela yeqela lekhowudi yongqamaniso olukhethekileyo.
Qala-yekisa indlela yongqamaniso:Iqela lekhowudi ngokwalo linolwazi lwalo ngokwamaqela ngokusebenzisa umgaqo okhethekileyo wekhowudi yekhowudi ekupheleni kokuthumela.
Kufakwe uhlobo olulodwa lwekhowudi yekhowudi yeqela:Ibhekisa ekufakeni iikhowudi ezininzi zongqamaniso zongqamaniso lwesakhelo kulandelelwano lwesimboli egqithisiweyo.
Kukho ubukhulu becala iindidi ezimbini zofakelo olusembindini kunye nofakelo lwekhefu.Ufakelo oluphakathi, olukwabizwa ngokuba lufakelo oluhambelanayo, lufuna ukuba ibhloko ekhethekileyo yongqamaniso lwesakhelo ineempawu ezibalaseleyo zokuzihambela.Iqela lekhowudi yongqamaniso yesakhelo esisetyenziswa ngokuqhelekileyo yikhowudi yeBarker.Ufakelo lwesithuba.Ikwaziwa njengofakelo olusasaziweyo, ulandelelwano olulula lwebhayisikile yethutyana ludla ngokusetyenziswa njengekhowudi yongqamaniso lwesakhelo, kwaye ifakwe ngokufanayo kumjelo wekhowudi yolwazi.
Isizathu sokuba i-data link layer idibanisa i-bits kwizakhelo kwaye idlulise kukuba xa kwenzeka impazamo, isakhelo esineempazamo kuphela sinokugqithiselwa kwakhona, kwaye akuyimfuneko ukuphinda uthumele yonke idatha, ngaloo ndlela kuphuculwe ukusebenza kakuhle.Iitshekhisum zidla ngokubalwa kwisakhelo ngasinye.Xa isakhelo sifika kwindawo ekuyiwa kuyo, i-checksum ibalwa kwakhona, kwaye ukuba ihluke kwi-checksum yokuqala, impazamo inokufunyanwa.
Oku ngasentla yingcaciso yolwazi "I-OSI-Data Link Layer-Frame Synchronization Function" eziswa yi-Shenzhen HDV photoelectric Technology Co., Ltd. Iimveliso zonxibelelwano eziveliswe yikhava yenkampani:
Iindidi zeemodyuli: iimodyuli zefiber optical, Iimodyuli ze-Ethernet, iimodyuli ze-fiber optical transceiver, iimodyuli zokufikelela kwifiber optical, Iimodyuli ze-SSFP ezibonakalayo, kwayeI-SFP optical fibers, njl.
Udidi lwe-ONU: EPON ONU, AC ONU, ifayibha optical ONU, CATV ONU, GPON ONU, XPON ONU, njl.
iklasi ye-OLT: Ukutshintsha OLT, GPON OLT, EPON OLT, unxibelelwano OLT, njl.
Iimveliso zemodyuli ezingentla zinokubonelela ngenkxaso yeemeko ezahlukeneyo zenethiwekhi.Iqela le-R&D elinobuchwephesha kunye nelomeleleyo linokunceda abathengi abanemiba yobugcisa, kwaye iqela leshishini elicingayo nelinobuchule linokunceda abathengi bafumane iinkonzo ezikumgangatho ophezulu ngexesha lokubonisana kwangaphambili kunye nomsebenzi wasemva kokuvelisa.Wamkelekile kuwe qhagamshelana nathi kulo naluphi na uhlobo lombuzo.
