Xa kufikwa kumba wokwenza ngokwezifiso iintambo, umgangatho kunye nokusebenza kubalulekile ekufezekiseni usulelo oluthembekileyo nolusebenzayo. Le ntambo idlala indima ebalulekileyo kumashishini ahlukeneyo, kunxibelelwano lwefowuni ukuze usasazwe, kwaye iqinisekise ukuba amandla abo okwenza kunye nokuhambisa ibalulekile. Kweli nqaku, siza kuphonononga izinto eziphambili ekufuneka siqwalasele xa kuvavanywa umgangatho weentambo ze-acaxial kunye nendlela yokujonga amandla abo okwenza kunye nokuhambisa. Ukongeza, siya kuqaqambisa izibonelelo zokusebenza kunye nomvelisi we-coaxial ye-coaxial ye-coaxial ye-coble yesidingo sakho
Ukuvavanya umgangatho wezinto ezibonakalayo ze-coaxial yesiko
Unomgangatho wezinto ezisetyenzisiweyo ngokwezifiso ze-Coaxial Cable yenye yezona zinto zibalulekileyo ekumiseleni ukusebenza kwabo ngokubanzi. Ukusuka kumqhubi wesifundo kwi-inshunzle, icandelo ngalinye lidlala indima ekuqinisekiseni ukuhanjiswa ngokoqobo.
Ukubaluleka kwezinto zokuqhuba:
Umqhubi wesifundo yeyona nto iphambili yayo nayiphi na intambo ye-ceble, enoxanduva lokudlulisela uphawu lombane. Abaqhubi abakwinqanaba eliphezulu benziwa ngobhedu okanye ngolwabiwo lobhedu, njengoko ezi zixhobo zibonelela ngempumelelo. Ezinye iintambo ze-acxial zesiko sokusebenzisa izixhobo njengegolide okanye i-silver-plated yobhedu ukuze ingqibelelo engcono. Xa kuvavanywa intambo ye-acfanial ye-akoial, qinisekisa ukuba umqhubi wenziwa ngemiba yenqanaba eliphezulu eqinisekisa ukunganyangeki okusebenzayo kunye nokuhanjiswa ngendlela efanelekileyo.
Ukukhetha i-interser
I-inshuler ye-inshuler ejikeleze umqhubi ejikeleze ihambo ephambili ekunciphiseni ilahleko yomqondiso kunye nokukhusela intambo kumbandela wangaphandle. I-COAGAIL ye-Coaxial I-Cobble ihlala isebenzisa izixhobo ezinjenge-polythylene, ne-TEFLO, okanye igwebu lenterfayili. Ubungqingqwa kunye neDiectoric rhoqo yezinto zokufakwa kwezinto zichaphazela amandla entambo ukugcina umgangatho womqondiso kumgama omde. Intambo esemgangathweni ephakathi ye-adial kufuneka inyuswe ngokufanelekileyo i-subsal yokuthintela ukonakaliswa komqondiso kwaye kunciphisa ukuphazamiseka kwe-electromagnetic (i-EMI).
Ukukhuselwa ukukhuselwa kwabantu:
Ukukhusela intambo yenye into ebalulekileyo echaphazela ukuhanjiswa kwesiginali kunye nokuqina. Ukufihlwa okuhle kuthintela i-EMI yangaphandle kunye ne-crostalk, enokugqwetha uphawu. Jonga iindibano ze-ceble ze-ceble ze-ableble ezibonisa iindawo ezininzi zokukhusela, ezinjengeebhulukhwe zobhedu, izihlangu ze-foil, okanye zombini, ukuqinisekisa ukhuseleko oluphezulu.
Ngokunikela ingqalelo kumgangatho wezinto ezisetyenzisiweyo, unokuchaza ukuba i-coaxial ye-ac dixial iya kuzisa ukusebenza kunye nokuqina okufunekayo isicelo sakho.
Ukuvavanya ukuqina kweentambo ze-coaxial
Ukuphathwa kothungelwano lweentambo ze-chiaxial kugqitywa kukukwazi kwabo ukuhambisa idatha okanye imiqondiso ngaphandle kwelahleko enkulu, ukugqwetha, okanye ukulibazisa. Izinto ezininzi zinefuthe kumgangatho wokudluliselwa, kwaye ibalulekile ekuvavanyweni kwezi xa ukhetha iintambo ze-ameial.
Ilahleko yomqondiso kunye ne-Attinatus:
I-Attinung ibhekisa kwilahleko yamandla eMiqondiso njengoko ihamba kwintambo ye-avial. Isixa-mali sophuhliso sixhomekeke kuyilo lwentambo, kubandakanya nezinto ezisetyenzisiweyo kunye nobungqingqwa bomaleko weDiectric. I-conves ephakathi ephakathi ye-acyaxial yenzelwe ukunciphisa ilahleko yomqondiso, ivumela umqondiso ukuba uhambe imigama emide ngaphandle kokuthambisa. Unokuvavanya amandla othungelwano ngokukhangela ixabiso lentambo, ngokuqhelekileyo kwi-decibels nganye kwimitha nganye (i-DB / m). Ixabiso eliphantsi lothintelo libonisa umgangatho wothumelo olungcono.
I-Bandwidth kunye nempendulo ye-frequency:
I-bandwidth yentambo ye-coaxial luluhlu lwee-frequem ezinokudlulisela ngempumelelo ngaphandle kwelahleko ebalulekileyo. I-Coloxial ekumgangatho ophezulu Umzekelo, iintambo ezisetyenziswa kusulelo lwedatha ehamba ngesantya esiphezulu, njengebhendi ebanzi okanye i-table ye-thebhu, kufuneka ikwazi ukuphatha imiqondiso ephezulu kakhulu ngaphandle kokugqwetha. Xa kuvavanywa ukubanakho ukuhanjiswa kweentambo ze-acyaial ze-acaxial, qinisekisa ukuba intambo yenzelwe ukuphatha i-bandwidth efunekayo yesicelo sakho.
Buyisela ilahleko kunye nokucingisisa:
Enye into ekufuneka iqwalaselwe kukulahleka kwelahleko, nto leyo ibonakalisa ubungakanani bophawu lokubuyela kumthombo ngenxa yokufumana i-mismatches yentambo. I-conbs ye-akoxial eneelahleko eziphantsi zokubuya ziqinisekise ukuba uninzi lomqondiso ludluliselwa ngaphandle kokucingisisa, kukhokelela ekususeni idatha kunye nokudluliselwa kwedatha. Intambo esemgangathweni ephezulu kufuneka ibe nemfuyo efanelekileyo (ihlala i-50 okanye i-50 yee-OHMS) yokutshatisa iimfuno zenkqubo, ukunciphisa ukucingisisa kunye nokupheliswa kwesiginali.
Ngokuvavanya ezi mpawu zothumelo, ungagqiba ukuba intambo ye-acfanial yesiko iya kuhlangabezana neemfuno zakho zomsebenzi wakho.
