I-topology yenethiwekhi esetyenziswa ngokuqhelekileyo ukupheliswa kwesakhiwo sebhasi, ayixhasi inethiwekhi engqukuva okanye emile okwenkwenkwezi.Yonke i-node i-serial exhunywe ngebhasi enye yinto efanelekileyo, kumfanekiso ongentla, i-topology yenethiwekhi ngokubanzi ye-A8-05B inkqubo ibonisiwe.Ii-N nodes ziqhagamshelwe kwinethiwekhi yeengongoma ezininzi.Kwizantya eziphezulu kunye nemigca emide, ukuchasana kokuphelisa kuyimfuneko kuzo zombini iziphelo zomgca ukuphelisa ukubonakaliswa.Sebenzisa i-100 Ω izixhasi kwiziphelo zombini (ifuna kuphela ukuba ubude bocingo > 2km).Uthungelwano kufuneka luyilwe njengomgca omnye onamathontsi amaninzi, hayi njengenkwenkwezi.Nangona ubude bekhebula bubonke bunokuba bufutshane kuqwalaselo lwenkwenkwezi, ukupheliswa okwaneleyo akusenakwenzeka kwaye umgangatho womqondiso unokuhla kakhulu.Kumzobo woku-1 obonisa ngokulandelayo, b, d, f ludibaniso oluchanekileyo kwaye a, c, e lunxibelelwano olungalunganga.
Umzobo woku-1
Xa usebenzisa i-shield network wire (STP), Kufuneka ugcine ukuqhubeka komgangatho okhuselayo ogudileyo, kwaye udibanise uMhlaba kwindawo enye, njengoko kubonisiwe kwidayagram.
Kufuneka ucingo
Inkqubo esetyenzisiweyo ye-CAT-5E UTP kunye nentambo ye-STP.
Indlela yokukhetha intambo ye-CAT-5E efanelekileyo?
Ukumelana nocingo ngalunye kufuneka ≤35Ω xa ubude bumalunga ne-305M (ubude be-FCL).
Isikhululo somnyango ukuya kwiSibonelelo soMbane sisetyenziswe iRVV4*0.5, ukutshixa iRVV2*0.5 esetyenzisiweyo.
Isilumkiso:
Umfanekiso wesitishi somnyango awuyi kuboniswa ngokupheleleyo kwiscreen seVisual Room-station xa Igumbi-isikhululo sahluke kakhulu kumbane wevidiyo, kwiindawo ezifanelekileyo kwibhasi yokwakha ukwandisa umbane unokusombulula le ngxaki.Ubonelelo lwamandla lwevidiyo ngokubanzi oluvela kwindawo ebonwayo Isikhululo segumbi sowona mgama mkhulu awunakudlula iimitha ezingama-30.

Umfanekiso wesiphumo
Kutheni ungasebenzisi i-RJ-45 kuqhagamshelwano?
Ngenxa yokuba umgangatho we-RJ-45 wenzelwe ukusetyenziswa ngaphakathi emnyango kuphela, awunabungqina bokufuma kwaye kulula kakhulu ukungcoliswa okanye ukufakwa kwi-oxidized.Ukuba iNtloko ye-RJ-45 iphukile, kukho iingcali ezibambe izixhobo zobugcisa ezifunekayo ukulungisa iphutha, oku kuya kubangela iindleko eziphezulu zokugcina.
IScotchlok yile nto kanye siyifunayo.Ngaphezulu kweminyaka engama-45 eyadlulayo, i-3M yazisa isiqhagamshelo sokuqala se-insulation displacement-i-Scotchlok Connector UR.Namhlanje, ngokunyuka kwemfuno ye-high-speed kunye ne-high-bandwidth networks, uchungechunge olupheleleyo lwe-3M izixhumanisi kunye nezixhobo ziye zavela kwakhona.Nceda undwendwele www.3M.com ngolwazi oluthe kratya lweScotchlok.
