M'munda waukulu waukadaulo, pali ngwazi imodzi yokha yomwe imatsimikizira kutumiza kwa data kosalala ndi kulumikizana kopanda cholakwika pamapulogalamu ambiri - 50 ohm coaxial zingwe. Ngakhale ambiri sangazindikire, ngwazi yosadziwikayi imagwira ntchito yofunika kwambiri m'mafakitale kuyambira pa telecommunication mpaka zamlengalenga. Mubulogu iyi, tiwulula zinsinsi za 50 ohm coaxial chingwe ndikuwunika zambiri zaukadaulo, maubwino ndi magwiritsidwe ake. Tiyeni tiyambe ulendowu kuti timvetsetse mizati ya kulumikizana kopanda msoko!
Zaukadaulo ndi kapangidwe kake:
50 ohm coaxial chingwendi chingwe chotumizira chomwe chili ndi vuto la 50 ohms. Kapangidwe kake kamakhala ndi zigawo zinayi zazikulu: woyendetsa wamkati, dielectric insulator, chishango chachitsulo ndi sheath yakunja yoteteza. Woyendetsa wamkati, nthawi zambiri amapangidwa ndi mkuwa kapena aluminiyamu, amanyamula chizindikiro cha magetsi, pamene dielectric insulator imakhala ngati insulator yamagetsi pakati pa woyendetsa mkati ndi chishango. Kutchinga kwachitsulo, komwe kumatha kukhala ngati waya woluka kapena zojambulazo, kumateteza kusokoneza ma radio frequency akunja (RFI). Pomaliza, sheath yakunja imapereka chitetezo chamakina ku chingwe.
Kuwulula maubwino:
1. Kukhulupirika kwa Chizindikiro ndi Kutayika Kwapang'onopang'ono: The 50 ohm khalidwe impedance ya mtundu wa chingwe ichi imatsimikizira kukhulupirika kwa chizindikiro, kuchepetsa kusinkhasinkha ndi kusagwirizana kwa impedance. Imawonetsa kutsika pang'ono (ie kutayika kwa ma sign) pamtunda wautali, ndikupangitsa kuti ikhale yoyenera kugwiritsa ntchito pafupipafupi. Makhalidwe otsika otsikawa ndi ofunikira kuti mukhalebe odalirika komanso apamwamba kwambiri.
2. Wide frequency range: 50 ohm coaxial chingwe imatha kunyamula ma sipekitiramu ambiri, kuyambira ma kilohertz angapo mpaka magigahertz angapo. Kusinthasintha kumeneku kumathandizira kukwaniritsa zosowa zamitundu yosiyanasiyana, kuphatikiza matelefoni, kuwulutsa, kuyesa ndi kuyeza kwa RF, kulumikizana kwankhondo ndi makampani opanga ndege.
3. Chitetezo Champhamvu: Mtundu wa chingwe uwu umakhala ndi chitetezo cholimba chachitsulo chomwe chimapereka chitetezo chabwino kwambiri ku kusokoneza kosafunika kwa maginito amagetsi ndikuwonetsetsa kufalitsa chizindikiro choyera. Izi zimapangitsa kuti ikhale yabwino kwa mapulogalamu omwe amakonda RFI, monga makina olumikizirana opanda zingwe ndi ma seti oyezera pafupipafupi.
Mapulogalamu olemera:
1. Kutumiza mauthenga: M’makampani opanga mauthenga, zingwe za coaxial 50-ohm zimakhala ngati nsanamira yotumizira mauthenga a mawu, mavidiyo, ndi deta pakati pa nsanja zoyankhulirana ndi masiwichi. Imagwiritsidwanso ntchito kwambiri pamanetiweki am'manja, ma satellite communications, ndi Internet Service Providers (ISPs).
2. Asilikali ndi ndege: Chifukwa cha kudalirika kwake kwakukulu, kutayika kochepa komanso ntchito yabwino yotetezera, mtundu wa chingwe uwu umagwiritsidwa ntchito kwambiri m'magulu ankhondo ndi ndege. Amagwiritsidwa ntchito pamakina a radar, ma avionics, ma UAV (magalimoto osayendetsedwa ndi ndege), njira zoyankhulirana zamagulu ankhondo, ndi zina zambiri.
3. Zida zamafakitale ndi zoyesera: Kuchokera ku oscilloscopes kupita ku network analyzers, 50-ohm coaxial cable imagwiritsidwa ntchito kwambiri m'ma laboratories ndi zida zamakampani. Kuthekera kwake kufalitsa ma siginecha apamwamba kwambiri osataya pang'ono kumapangitsa kukhala koyenera pakuyesa kuyesa ndi kuyeza.
Pomaliza:
Ngakhale nthawi zambiri amanyalanyazidwa,50 ohm coaxial chingwendi gawo lofunikira m'mafakitale ambiri, kuwonetsetsa kuti kulumikizana kopanda chilema komanso kutumiza kwa data kodalirika. Makhalidwe ake otsika otayika, chitetezo cholimba komanso kuchuluka kwa ma frequency angapo kumapangitsa kuti ikhale yofunika kwambiri pamagwiritsidwe ntchito pafupipafupi. Ngwazi yosadziwikayi imagwira ntchito yofunika kwambiri pamayendedwe olumikizirana matelefoni, ukadaulo wazamlengalenga, zida zoyesera zama mafakitale ndi magawo ena. Chifukwa chake, tiyeni tiyamikire zodabwitsa za 50-ohm coaxial chingwe, chothandizira mwakachetechete cholumikizira mopanda msoko muzaka za digito.
