Uma kukhulunywa ngokwezifiso izintambo ze-coaxial, ikhwalithi nokusebenza kubalulekile ekufezeni ukuhanjiswa kwedatha okuthembekile nokusebenza kahle. Lezi zintambo zidlala indima ebalulekile emidlalweni ehlukahlukene, kusuka ekuxhumaneni ngocingo kuya ekusakazweni, kanye nokuqinisekisa ukuqina kwazo nokudlulisela kwazo kubalulekile. Kulesi sihloko, sizohlola izinto ezibalulekile okufanele sizicabangele lapho sihlola ikhwalithi yezintambo zangokwezifiso zokusebenzisa imali futhi ukuthi ungabheka kanjani ukuqina kwazo namakhono okuhambisa. Ngokwengeziwe, sizogqamisa izinzuzo zokusebenza nomkhiqizi wekhebula othembekile wekhebula othembekile wesidingo sakho esithile
Ukuhlola ikhwalithi yezinto ezibonakalayo zezintambo zezezimali ze-coaxial
Ikhwalithi yezinto ezisetshenziswayo ezenziwe ngokwezifiso imihlangano yamakhebula yama-coaxial ngenye yezinto ezibaluleke kakhulu ekunqumeni ukusebenza kwazo jikelele. Ukusuka kumqhubi kuya ekufakweni, isakhi ngasinye sidlala indima ekuqinisekiseni ukuhanjiswa kahle kwesiginali.
Ukubaluleka Kwezinto Zokusebenza:
Umshayeli uyisici esiyisisekelo sanoma iyiphi ikhebula le-coaxial, obhekele ukudlulisa isiginali kagesi. Abaqhubi bekhwalithi ephezulu ngokuvamile benziwa ngethusi noma i-aloy yethusi, njengoba lezi zinto zokwakha zinikeza ukusebenza okuhle kakhulu. Ezinye izintambo zokukhokhisa ngokwezifiso zisebenzisa izinto ezinjengegolide noma zesiliva - zethuli-ezifuywayo zokuthembeka okungcono kwesiginali. Lapho uhlola ikhebula le-coaxial yangokwezifiso, qinisekisa ukuthi umqhubi wesifundo wenziwa ngezinto ezisezingeni eliphakeme eziqinisekisa ukumelana okuphansi nokuhanjiswa kahle kwesiginali.
Ukukhetha ukufakwa okulungile:
Ungqimba olusezingeni lokufakelwa ezungeze umqhubi wesifundo lubamba iqhaza elibalulekile ekunciphiseni ukulahleka kwesiginali nokuvikela ikhebula ekuphazanyisweni kwangaphandle. Izintambo ze-coaxial ngokwezifiso zivame ukusebenzisa izinto ezifana ne-polyethylene, i-teflon, noma igwebu lokufakelwa. Ubukhulu kanye ne-dielectric njalo ye-insulation matering ithonya ikhono lentambo lokugcina ikhwalithi yesiginali ngamabanga amade. Ikhebula eliphakeme lekhwalithi ephezulu ye-coaxial kufanele likhethe kahle ukufakwa okuvimbela ukonakaliswa kwesiginali futhi kunciphise ukuphazamiseka kwe-electromagnetic (EMI).
Ukuvikela ukuvikela okungaphazanyiswa:
Ukuvikelwa kwentambo ezungeze ikhebula kungenye into ebalulekile ethinta ukuhanjiswa nokuqina kwesiginali. Ukuvikelwa okuhle kuvimbela i-EMI ne-Crosstalk yangaphandle, engahlanekezela isiginali. Funa imihlangano yekhebula le-COAXIAL COUXIAL ebeka izingqimba eziningi zokuvikela, njenge-Copper Braids, izihlangu ze-foil, noma zombili, ukuqinisekisa ukuvikelwa okuphezulu ekuphazanyisweni.
Ngokunaka ikhwalithi yezinto ezisetshenzisiwe, unganquma ukuthi ngabe izintambo ze-coaxial zangokwezifiso zizoletha ukusebenza nokuqina okudingayo ukuthola uhlelo lwakho lokusebenza.
Ukuhlola ukuqina kwezintambo zezezimali ze-coaxial
Amandla okuhambisa amakhethini e-coaxial anqunywa ngamakhono abo okudlulisela idatha noma amasiginali ngaphandle kokulahleka okukhulu, ukuhlanekezela, noma ukubambezeleka. Izici eziningana zithonya ikhwalithi yokudlulisela, futhi kubalulekile ukuhlola lokhu lapho ukhetha izintambo zekhemikhali.
Ukulahleka kwesiginali kanye ne-attenuation:
I-Attenuation ibhekisela ekulahlekelweni kwamandla wesiginali njengoba lihamba ngentambo ye-coaxial. Inani le-attenuation lincike ekwakhiweni kwentambo, kufaka phakathi izinto ezisetshenziswayo kanye nobukhulu bengqimba ye-dielectric. Izintambo zekhwalithi ephezulu yezezimali zenzelwe ukunciphisa ukulahleka kwesiginali, okuvumela isiginali ukuthi ihambe amabanga amade ngaphandle kokuwohloka. Ungahlola amandla okuhambisa ngokubheka inani le-attenciation le-Cable, ngokujwayelekile kulinganiswe kuma-decibels ngamamitha (DB / M). Inani eliphansi le-atchenuation libonisa ikhwalithi yokuhambisa engcono.
Impendulo ye-bandwidth nemvamisa:
I-bandwidth yekhebula le-coayial libanga lamafrikhwensi angawadlulisa ngempumelelo ngaphandle kokulahleka kwesiginali okubalulekile. Izinga eliphakeme ngokwezifiso izintambo ze-coaxial ze-coaxial kufanele zisekele ububanzi obuhlukahlukene, kuya ngohlelo lokusebenza. Isibonelo, izintambo ezisetshenziswa ekudluliseleni ngejubane eliphezulu, njenge-Broadband noma i-Cable TV, kufanele zikwazi ukuphatha amasignali afudumele aphezulu ngaphandle kokuhlanekezela. Lapho uhlola amakhono okuhambisa amakhekhe amakhekhe angokwezifiso, aqinisekise ukuthi ikhebula lenzelwe ukuphatha umkhawulokudonsa odingekayo wesicelo sakho.
Buyisela ukulahleka nokuboniswa:
Enye into okufanele icatshangelwe ukulahleka kokubuyiselwa kwemali, okukala inani lesiginali eliboniswe emuva kulowo mthombo ngenxa yokuphazamiseka kwentambo. Izintambo ze-coaxial zenziwe ngokwezifiso ezinokulahlekelwa okuphansi kwembuyiselo ziqinisekisa ukuthi iningi lesiginali lidluliselwa ngaphandle kokukhombisa, okuholela ekuhanjisweni kwedatha okuhlanzekile. Intambo esezingeni eliphakeme kufanele ibe nokulimala okufanele (imvamisa engama-50 noma engama-75 ohms) ukufanisa izidingo zohlelo, ukunciphisa ukuboniswa kanye nokuwohloka kwesiginali.
Ngokuhlola lezi zici zokuhambisa, unganquma ukuthi ikhebula le-coaxial langokwezifiso lizohlangabezana nezidingo zakho ezithile zokusebenza.
Ukuhlola amakhono okuhambisa wezintambo zangokwezifiso zezezimali
Amandla okuhambisa amakhethini e-coaxial anqunywa ngamakhono abo okudlulisela idatha noma amasiginali ngaphandle kokulahleka okukhulu, ukuhlanekezela, noma ukubambezeleka. Izici eziningana zithonya ikhwalithi yokudlulisela, futhi kubalulekile ukuhlola lokhu lapho ukhetha izintambo zekhemikhali.
Ukulahleka kwesiginali kanye ne-attenuation:
I-Attenuation ibhekisela ekulahlekelweni kwamandla wesiginali njengoba lihamba ngentambo ye-coaxial. Inani le-attenuation lincike ekwakhiweni kwentambo, kufaka phakathi izinto ezisetshenziswayo kanye nobukhulu bengqimba ye-dielectric. Izintambo zekhwalithi ephezulu yezezimali zenzelwe ukunciphisa ukulahleka kwesiginali, okuvumela isiginali ukuthi ihambe amabanga amade ngaphandle kokuwohloka.

Ngokuhlola lezi zici zokuhambisa, unganquma ukuthi ikhebula le-coaxial elenziwe ngezifiso lizohlangabezana nezidingo zakho ezithile zokusebenza.
Kungani ukhethe umkhiqizi wekhebula othembekile wekhebula othembekile?
Ukukhetha okulungile okwenziwe ngabakhiqizi bekhebula amakhebula ama-coaxial kubalulekile ukuze kuqinisekiswe imikhiqizo esezingeni eliphakeme ehlangabezana nezidingo zakho ezithile. Umkhiqizi othembekile anganikezeli kuphela kuphela amakhekhe akho asebenza kahle ngokwezifiso kodwa futhi anikeze ukwesekwa okubalulekile kuyo yonke inqubo yokuklama nenqubo yokukhiqiza.
Ubuchwepheshe kanye nesipiliyoni:
Umkhiqizi othembekile uzoba nesipiliyoni esibanzi ekukhiqizeni izintambo ze-coaxial zangokwezifiso ezihlangabezana nezindinganiso zakamuva zezimboni. Kufanele bakwazi ukunikeza umhlahlandlela ekukhetheni izinto ezifanele, izakhi zemiklamo, kanye nemiklamo esuselwa kwizidingo zakho, noma ngabe ukuhanjiswa kwedatha, izinhlelo zokusebenza ze-RF, noma amasiginali wevidiyo.
Izisombululo ngokwezifiso zezidingo zakho:
Ukusebenza nomhlinzeki wekhebula odumile we-coaxial cable kukuvumela ukuthi uvumelanise amakhekhe ekucacisweni kwakho ngqo. Noma ngabe udinga ubude obuthile, uhlobo lwesixhumi, noma ikhambi lokuvikela, umenzi omuhle uzosebenza nawe ukuklama imihlangano yekhebula le-coaxial cable efanelekile yesicelo sakho. Kufanele futhi bakwazi ukwenza ukuhlolwa okuphelele nokuhlolwa kwekhwalithi yekhwalithi ukuqinisekisa ukuthi ikhebula ngalinye lisebenza ngokuthembekile nangokungaguquki.
Ukuxhaswa Kwamakhasimende Nesenzo Sokuthengisa Emuva:
Umhlinzeki othembekile uhlinzeka ngokusekelwa okuhle kwamakhasimende nensizakalo yokuthengisa ngemuva kokuthengisa, uqinisekise ukuthi noma yiziphi izingqinamba ezinezingqinamba zakho ze-coaxial zakho zibhekwa ngokushesha nangendlela efanele. Funa abakhiqizi abahlinzeka ngamawaranti, ukusekelwa kwezobuchwepheshe, kanye neziteshi ezilula zokuxhumana ukuqinisekisa ukuthi ungathembela kubo kuyo yonke imali yezintambo zakho.
Ukugcina
Ikhwalithi, ukuqina, kanye namakhono okuhambisa amakhekhe amakhekhe aqanjiwe yizici ezibalulekile okufanele zicatshangelwe lapho ukhetha izintambo zezicelo zakho. Ngokugxila kwikhwalithi yezinto ezibonakalayo, ukumelana kwezemvelo, amandla okuhambisa, kanye nokusebenza kokudlulisela, ungaqinisekisa ukuthi izintambo zakho ze-coaxial zenziwe zihlangabezana nezidingo zakho futhi zinikeze imiphumela ethembekile, esebenza kahle. Ukusebenza nomkhiqizi wekhebula othembekile wekhebula othembekile futhi umphakeli kuzokusiza ukufeza umphumela omuhle kakhulu, ngezixazululo ezenziwe ngemali kanye nensizakalo yamakhasimende ayingqayizivele.
