Iilahleko eziqhelekileyo kwi-50 Ohm Coaxial Cables

Iintambo ze-coaxial ziingcingo ezithumela ulwazi ukusuka kwindawo ukuya kwenye. Sisebenzisa iintambo rhoqo ebomini bethu njengoko zisetyenziselwa ukuthumela imiqondiso yevidiyo kunye nesandi, ukuqhagamshela kwi-Intanethi kunye ne-TV yentambo. Iquka iNkxaso yaMacandelo Intambo ye-coaxial inezahlulo ezininzi. Ucingo oluphakathi oluphakathi luthwala ulwazi. Ikhaka lesinyithi lokuthintela ukuphazamiseka kwe-electromagnetic, kunye nebhatyi yangaphandle eyikhusela emonakalweni ngoku iba yeyona ndawo incinci yentambo. Olu hlobo lokhuselo olunamaleko lubalulekile kuba lunika amandla emiqondiso kwaye luthintele iimeko ezigwenxa ekubeni zenze buthathaka ezo mpawu. 

Nangona kunjalo iSignal iseyehla ngamanye amaxesha, nangona kunjalo, uphawu luyehla nangazo zonke ezi maleko zokhuseleko. Ngokulahleka komqondiso, sithetha ngomqondiso oncitshisiweyo. Oku kunokwenzeka ngezizathu ezininzi, kwaye kubalulekile ukuba uzazi. Kule bhlog, uya kufunda malunga neminye imiba enokuthi ikukhathaze nge-50 ohm coaxial cable kunye nokuba inokulungiswa ngokulula kangakanani ukwenza intambo yakho ibonakale. 

I-50 ye-Ohm ye-Coaxial Cable Signal Loss Izizathu

Kukho izinto ezininzi ze-50 ohm coax enokubanakho ukuphulukana nophawu lwakho, nto leyo (ngethemba) ivangeli ehlekisayo kuye nabani na owakhe wazama umbane wokusawula kuyo nayiphi na inkqubo. Ukungcola nothuli okanye i-oyile okanye amanzi anetyuwa aya kuba sisizathu esikhulu ngenxa yokuba konke oku kwenzekayo. Oku kungcola kunokuphazamisana nomqondiso kwaye kwenze buthathaka. Oku kufana nokuphulaphula umntu ethetha xa kukho ingxolo eninzi - izinto ziyaxhuma kwaye awukwazi ukuqonda. 

Ukulahleka komqondiso Esi sesinye sezizathu eziphambili zokulahleka komqondiso, into eyaziwa ngokuba yi-electromagnetic interference. Iziphazamiso ezahlukeneyo zinokubangela uhlobo olunjalo lwezikroba. Oku kunokuquka izixhobo ezifana neeselfowuni, iirotha zeWi-Fi okanye izixhobo zasekhaya ezinjengeemicrowaves kunye neefriji. Ezi zixhobo zivelisa imiqondiso esasazwayo, kwaye le miqondiso yosasazo inokuphazamisana nemiqondiso kwintambo yakho ye-coaxial ekhokelela ekunciphiseni kwamandla. 

Le yindlela umgama oyichaphazela ngayo ilahleko yomqondiso weCable Coaxial

Ngokukwanjalo amandla omqondiso womelele kakhulu, umisela kancinci ulwimi kunye nomgama nawo. Okukhona umqondiso uhamba kwi-coaxial I-rg59 intambo ye-coaxial, iba buthathaka ngakumbi. Le yinto onokuthi uyifumane ukuba intambo yakho ye-coaxial inde kakhulu, okuthetha ukuba nje ukuba uphawu lufikelele kwithagethi yalo ekujoliswe kulo alunamandla njengangaphambili. Yicinge njengokukhwaza usuka kwelinye icala uye kwelinye unqumla iholo, okukhona usimka, kokukhona kuya kuba nzima ukuba umntu kwelinye icala akuve ngokupheleleyo. 

Ukunciphisa uphazamiseko lwesignali kuthungelwano lweentambo ze-coax

Ukuba uneengxaki zesignali kuthungelwano lwentambo ye-coaxial, ke apha siza kubonisa ezinye iindlela zokunciphisa loo miba yesignali. Ukuba uzifumana ulahlekelwa ngumqondiso ngenxa yezixhobo zombane ezimbalwa, jonga ukuba ingakwazi na ukuhambisa intambo yakho ye-coaxial ukusuka kweseleyo ngaphandle kwelo qela lithile, ihamba kanye kuloo mgca uxwesileyo. Ngokufana nendlela ukusuka kwingxolo enkulu kunokukunceda ukuba uve ngcono, oku kuya kunceda ukugcina umqondiso womelele kwaye ucacile. 

Esinye isisombululo esinokubakho ingxaki kukusebenzisa iintambo ze-coaxial eziza nezikhuselo ezimbini zentsimbi. Oku kukhuselwe kabini rg213 intambo. Oku kunokunceda ukuqinisekisa umqondiso ocacileyo oqinileyo kuyo yonke indlela phantsi kwentambo, kwaye uya kunika ukhuseleko olungcono ekuphazamisekeni. 

UkuBuyisa Ukulahleka kweSignali ye-50 Ohm Coax Cable

Kukho into esinokuyenza ukuzama ukusombulula ilahleko yophawu oluqhelekileyo lweentambo ezingama-50 ohm coaxial. Inye indlela elungileyo yokuyilungisa le nto - i-booster yomqondiso. I-Signal Booster — sisixhobo esikhethekileyo esiya kuphucula umqondiso. Ngokwandisa lo mqondiso, iyakwazi ukuya phambili. Amacandelo e-analog kwinkqubo ajika ulwazi lwedijithali lube luphawu lombane olunokuthi ke lugqithiswe ngokufanelekileyo kumgama omde ngaphandle kokulahlekelwa nantoni na. 

Kungenjalo ungakhetha imigca enoxhathiso oluncinci. Iintambo ezinoxhathiso oluncinci zithetha umqobo onganeno kumqondiso oxhomekeke kuwo ngoko kuya kubakho ukulahleka komqondiso omncinci. Ewe, umqondiso uya kuba ngcono ukuncipha kokuchasana kwentambo. 

Ke, ekugqibeleni, ukulahleka komqondiso kwintambo ye-coax kunokwenzeka ngenxa yezizathu ezininzi zokungcola, ukuphazamiseka kwazo naziphi na izixhobo kunye nomgama ohanjwe ngumqondiso. Ngokuziqonda ngcono ezi zizathu, ungasebenzela ukuzilungisa ukuze uqinisekise ukuba inethiwekhi yakho yentambo ye-coaxial isebenza ngcono kakhulu. Unokusebenzisa i-boosters yesignali okanye ukunyanzeliswa okuphantsi ixabiso cable coaxial ukuqinisa umqondiso ukuba unenkathazo yokufumana eyomeleleyo Hlala ukhusela iintambo zakho zokhuseleko oluphezulu. Sebenzisa iingcebiso kunye namaqhinga angasentla ukukunceda ukuba usebenzise inethiwekhi yentambo ye-coaxial ngokufanelekileyo ngakumbi, unikezela ngesandi esicacileyo kunye neempawu zevidiyo.
