Mu digito nthawi kugawikana multiplexing kulankhulana dongosolo, kuti molondola kulekanitsa zizindikiro nthawi kagawo, mapeto kutumiza ayenera kupereka chiyambi chizindikiro cha chimango chilichonse, ndi ndondomeko kuzindikira ndi kupeza chizindikiro pa mapeto kulandira amatchedwa chimango kalunzanitsidwe.Pali mitundu iwiri yamalumikizidwe a chimango: njira yoyambira kuyimitsa ndikuyika njira yapadera yolumikizirana.
Njira yolumikizira kuyimitsa:Gulu la ma code palokha lili ndi chidziwitso chake chamagulu pogwiritsa ntchito lamulo lapadera la code code kumapeto kwa kutumiza.
Kuyika njira yapadera yamagulu yolumikizirana:Zimatanthawuza kuyika zizindikiro zingapo zamalumikizidwe kuti zigwirizane ndi chimango mu mndandanda wa zizindikiro zopatsirana.
Pali makamaka mitundu iwiri ya kuyika kwapakati ndi kuyika kwapakati.Kuyika kwapakati, komwe kumadziwikanso kuti kuyika kogwirizana, kumafuna kuti chipika chapadera cholumikizira chimango chimakhala ndi mawonekedwe abwino kwambiri olumikizirana.Gulu lomwe limagwiritsidwa ntchito kwambiri ndi ma code a Barker.Kuyika kwapakati.Zomwe zimadziwikanso kuti distributed insertion, ndondomeko yosavuta ya periodic cyclic nthawi zambiri imagwiritsidwa ntchito ngati ndondomeko yolumikizira chimango, ndipo imayikidwa mofanana mumtsinje wa chidziwitso.
Chifukwa chomwe kusanjika kwa ulalo wa data kumaphatikiza ma bits kukhala mafelemu ndikutumiza ndikuti cholakwika chikachitika, chimango chokhacho chomwe chili ndi zolakwika chimatha kutumizidwanso, ndipo sikofunikira kutumizanso deta yonse, potero kuwongolera bwino.Ma checksum nthawi zambiri amawerengedwa pa chimango chilichonse.Chimango chikafika komwe mukupita, chekeni imawerengedwanso, ndipo ngati ili yosiyana ndi cheke choyambirira, cholakwika chikhoza kudziwika.
Zomwe zili pamwambazi ndizofotokozera za "OSI-Data Link Layer-Frame Synchronization Function" yobweretsedwa ndi Shenzhen HDV photoelectric Technology Co., Ltd.
Magawo a module: Optical fiber modules, Ethernet modules, Optical fiber transceiver modules, optical fiber access modules, SSFP Optical modules,ndiSFP kuwala ulusi, ndi zina.
Gulu la ONU: EPON ONU, AC ONU, Optical fiber ONU, CATV ONU, GPON ONU, XPON PA, ndi zina.
Gawo la OLT: Kusintha kwa mtengo wa OLT, Mtengo wa GPON OLT, EPON OLT, kulumikizana OLT, etc.
Zomwe zili pamwambazi zitha kuthandizira pazochitika zosiyanasiyana zapaintaneti.Gulu la akatswiri komanso lamphamvu la R&D litha kuthandiza makasitomala omwe ali ndi zovuta zaukadaulo, ndipo gulu loganiza bwino komanso laukadaulo litha kuthandiza makasitomala kupeza ntchito zapamwamba panthawi yokambirana zisanachitike komanso pambuyo popanga.Takulandirani ku Lumikizanani nafe pafunso lamtundu uliwonse.
