Coaxial cable - kuvimbika pamutengo unodhura

Nokuda kwemazuva ano ehurumende, ruzivo rwakakosha pamusika kune mishonga yakasiyana-siyana inovimbisa kusikwa kwehuwandu hwepamusoro uye hwakavimbika hwekufambisa nzvimbo yekufambisa. Chimwe chazvo ndechekodhairi yekambo. Zvinonyatsopupurirwa kana zvichishandiswa nokuda kwezvinangwa zvakasiyana-siyana.

Coaxial digital cable yakashandiswa zvikuru mumabasa akawanda emabasa evanhu. Saka, kunyanya, inoshandiswa pakuparidzirwa kweterevhizheni zviratidzo uye kubva kumakhamera eCCTV. Izvi ndezvokuti zvakakosha pakuendesa kure-frequency pulses. Kugadzirwa kwaro kwakakosha kunobvumira kuwana hukuru hwehutano hwekutakura chero zviratidzo zvisina kurasikirwa. Panguva imwecheteyo, ruzivo runotenderera runogona kutapudzwa pamakiromita akawanda kwazvo uye zvisingamboiti attenuation.

Kazhinji, iyo coaxial cable ine chimiro chinotevera: nheyo iri pakati (yakagadzirwa, semutemo, wemhangura) inowanikwa mune yakakwirira-polyethylene inopisa ine dielectric yemafuta uye yakavharwa neganda rakasungirirwa rematare masimbi esimbi. Pamusoro, yakafukidzirwa nekudzivirira kusungirirwa kwakaitwa ye polyethylene kana polyvinylchloride.

Coaxial cable, kufanana nedzimwe nhepfenyuro yekuendesa nhau, ine zvimwe zvakasiyana-siyana. Saka, zvakakosha kuziva kubva pakutanga, nekuda kweizvi, munzvimbo ipi ichashandiswa, uye chete ipapo sarudza mhando maererano nemhando dzakakodzera.

Saka, somuenzaniso, kambani ye coaxial yevhidhiyo yekucherechedza inofanira kuva nezvinhu zvinotevera:

1. Zvinokwanisika kutumira zvakawanda zvakadai sezvinobvira.
2. Izvo zvingasvibiswa pamiganhu iri pedo inotenderera iyo magetsi inoparidzirwa.
3. Maximum zvinokonzerwa nekudzivisa kune kunze kwezvazvinoita.
4. Kudzivirirwa kusapindira.

Uyewo chinhu chinonyanya kukosha ndiko kukanganisa kunopesana-kutengesa kwepamusoro, sezvo ichi ndicho chirevo chikuru chechigadzirwa chakadaro - chinogona kuiswa kune zvinyorwa zvinoparidzirwa panguva dzakaderera.

Mune dzimwe nguva, iyo coaxial cable inoshandiswa kutumira dhaka pakati pekugamuchira uye kutumira zvigadzirwa. Ndiyo imwe yenzira dzinowanzopfuura dzekutumira terevhizheni uye zviratidzo zvevhidhiyo. Kupararira kwaro hakusi kukonzerwa nekusaderera.

Pane imwe nhamba yakakura yemhando dzakasiyana dzemakanda ecoaxial. Kusiyana kwavo kukuru kunowanikwa mumamiriro avo ezvinhu. Panguva imwecheteyo zvakakodzera kucherechedza kuti chirevo chekuita kwezvinhu zvakasiyana-siyana zvezvigadzirwa zvakadaro zvakafanana.

Kana uchiri kusarudza kuisa pane imwe nzvimbo (pamba kana muhofisi) vhidhiyo kuongorora system, ipapo inonyanya kushandiswa midzi yekutumira ichava iyo coaxial cable. Iwe uchawana nzira yakatendeseka yemari shoma shoma. Uye kupararira uye nhamba yezvipo zvinowanikwa pamusika zvinokubvumira kusarudza chigadzirwa chichasangana neunoda iwe pachako. Ichi chichava mhinduro yakanakisisa yekushandura nzira yemhando ipi zvayo yekuoma kunzwisisa uye branching.
