Chidziwitso pa Udindo wa Feeder Cables mu Telecommunication Systems

Chiyambi:

Zingwe za feeder zimagwira ntchito yofunika kwambiri pamakina amakono amtundu wapadziko lonse lapansi. Izi ndi zingwe zapadera zomwe zimapangidwira kuti zithandizire kuyendetsa bwino komanso kuchita bwino kwa kufalitsa ma siginecha, makamaka pamawayilesi otumizirana mawayilesi. Chofunikira chokhala ndi zingwe zodyetsa chagona pakutha kwawo kupereka mphamvu ndi ma siginecha pakati pa zigawo zosiyanasiyana mkati mwadongosolo chifukwa cha kunyamula kwawo kwakukulu komanso kutayika kwa ma siginecha ochepa.

Mitundu ndi Mapangidwe a Zingwe za Feeder:

Nthawi zambiri, zingwe zodyetsa zimagawidwa m'magulu awiri: coaxial ndi fiber optic. Yoyamba, coaxial, imagwiritsidwa ntchito kwambiri mkati mwa ma radio frequency (RF) chifukwa chodzilekanitsa bwino ndi kusokonezedwa ndi ma electromagnetic akunja. Chingwechi chimakhala ndi kondakitala wamkati, insulator, kondakitala wakunja, ndi sheath yakunja. Kulinganiza kwakukulu pakati pa magwiridwe antchito ndi mtengo nthawi zambiri kumapezeka ndi zingwe za coaxial, zomwe zimawapangitsa kukhala chisankho chodziwika bwino pamsika wamatelefoni.

Kumbali inayi, zingwe za fiber optic zimagwira ntchito ngati njira yabwinoko komwe kumafunikira kufalitsa ma siginecha atali. Zingwe zimenezi zimagwiritsa ntchito ulusi wagalasi m'kati mwa thumba la insulated, zomwe zimathandiza kutumiza deta mwachangu.

Kugwiritsa Ntchito Zingwe za Feeder:

Zingwe za feeder zimagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana, kuphatikiza wailesi, matelefoni, ukadaulo wazidziwitso, zankhondo, ndi zina zambiri. Zomwe zimagwiritsidwa ntchito posuntha ma siginecha kuchokera pakatikati kupita ku mzere wogawa kapena zida zingapo ndizofunikira kwambiri zogulitsa. Zingwezi zimagwiritsidwa ntchito kwambiri pakukhazikitsa ma netiweki am'manja, pomwe ma siginecha amayenera kusamutsidwa kuchoka pagawo loyambira kupita kudongosolo la antenna.

Zingwe za feeder ndizofunikanso pakugwira ntchito kwa maukonde a wailesi yakanema. Iwo ali ndi udindo wonyamula ma siginecha akanema akanema kuchokera komwe kumapatsirana kwambiri kupita ku mlongoti wa anthu ammudzi, kuwonetsetsa kuti chithunzicho chili chabwino pochilandira.

Ubwino wa Feeder Cables:

Makamaka, mawonekedwe odziwika bwino a zingwe za feeder ndi kunyamula kwawo kwakukulu, kutayika kwa ma siginecha ochepa, komanso kukana kusokonezedwa ndi ma elekitiroma. Amapangidwa mwamphamvu kuti azigwira bwino ntchito m'mikhalidwe yovuta. Zingwezi ndizofunikira kwambiri pamakina ambiri owulutsa ndi kutumizirana matelefoni, zingwezi zimathandizira kutumiza ma siginecha molondola komanso mwachangu pamtunda wosiyanasiyana.

Pomaliza:

Pomaliza, zingwe za feeder ndi mwala wapangodya wamakono a telecommunication, makina owulutsa, ndi maukonde opanda zingwe, kuyendetsa dziko lomwe likudalira kwambiri kulumikizana kwachangu, koyenera, komanso kodalirika. Kutha kwawo kuchepetsa kutayika kwa ma sign, kukana kwawo kusokonezedwa, komanso kunyamula kwawo konse kumawapangitsa kukhala gawo lofunikira m'magawo osiyanasiyana azachuma. Pamene ukadaulo ukupitilira kupita patsogolo, pakufunikanso kuwongolera kofananira kwa zingwe zophatikizira, kutsimikizira kufunika kwawo m'dziko lathu lolumikizidwa.
