Umaleko womzimba usezantsi kwimodeli ye-OSI, kwaye umsebenzi wayo ophambili kukusebenzisa i-transmission medium ukubonelela uqhagamshelo olubonakalayo lomaleko wekhonkco ledatha ukuhambisa imilambo. Uluhlu lomzimba luchaza indlela ikhebula exhunywe ngayo kwikhadi lomnatha, kwaye yintoni iteknoloji yokudlulisa kufuneka isetyenziswe ukuthumela idatha kwikhebula, kwaye ichaza indlela yokufikelela kwinqanaba eliphezulu (idatha yekhonkco yedatha).
Ngesiqhelo, isixhobo esinedatha ethile yokusetyenzwa kunye nokuthumela nokufumana amandla kuthiwa yi-data terminal equipment (DTE), kwaye isixhobo phakathi kwe-DTE kunye ne-transmission medium ibizwa ngokuba yi-data circuit terminating equipment (DCE). I-DCE ibonelela ngoguqulo lomqondiso kunye nemisebenzi yokufaka iikhowudi phakathi kwe-DTE kunye nesixhobo sothumelo, kwaye inoxanduva lokuseka, ukugcina nokukhulula uqhagamshelo olubonakalayo. Ngenxa yokuba i-DCE iphakathi kwe-DTE kunye ne-transmission medium, ngexesha lenkqubo yonxibelelwano, i-DCE idlulisela idatha ye-DTE kwi-transmission medium kwelinye icala, kwaye kwelinye icala, kufuneka idlulise i-bit stream efunyenwe kwi indlela yosasazo ukuya kwi-DTE ngokulandelelanayo. , I-DCE idinga ukuhanjiswa kolwazi lwedatha kunye nolwazi lolawulo, kwaye kufuneka isebenze kwinqanaba eliphezulu lokulungelelaniswa, ngoko ke kuyimfuneko ukuqulunqa imigangatho yojongano lwe-DTE kunye ne-DCE, le migangatho yimigangatho yojongano lomzimba.
Kwaye lo mgangatho uchaza iimpawu ezine zomaleko womzimba:
1. Iimpawu zoomatshini: Chaza iimpawu zoxhumo lomzimba, khankanya inkcazo, imilo ye-interface, inani lokukhokela, inombolo kunye nokulungelelaniswa kwezikhonkwane ezisetyenziselwa uxhulumaniso lomzimba, njl.
2. Iimpawu zombane: Xa ucacisa ukuhanjiswa kweebhinari zebhinari, uluhlu lwe-voltage, ukulinganisa i-impedance, izinga lokuhambisa kunye nomda womgama wesignali kumgca, njl.
3. Iimpawu zokusebenza: zibonisa ukuba intsingiselo yenqanaba elithile lithetha ntoni, kunye nenjongo yomgca wesignali ojongano olungabonakaliyo.
4. Iimpawu zenkqubo (iimpawu zenkqubo): chaza iinkqubo zokusebenza kunye nobudlelwane bexesha lesiphaluka ngasinye somzimba
Oku ngasentla yingcaciso yolwazi lwe "OSI-Physical Layer Characteristics" eziswa nguShenzhen 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.
I-ONUudidi: EPON ONU, AC ONU, ifayibha optical ONU, CATV ONU, GPON ONU, XPON ONU, njl.
OLTiklasi: Ukutshintsha OLT, GPON OLT, EPON OLT, unxibelelwanoOLT, njl.
Iimveliso zemodyuli ezingentla zinokubonelela ngenkxaso yeemeko ezahlukeneyo zenethiwekhi. Iqela le-R&D elinobuchule 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 nathingenxanaluphi na uhlobo lombuzo.
