20 30 50 Pair CAT 3 UTP Telephone Cable 24 AWG BC 1000 FT

Chingwe cha foni cha CAT3 (UTP) ndi chingwe chopindika chosatetezedwa chomwe chimapangidwa kuti chinyamule deta moyenera pa liwiro la 10 Mbps, ndi bandwidth yomwe ingathe kukhala 16 MHz. Ndi cha banja la miyezo ya zingwe zamkuwa zomwe zimagwiritsidwa ntchito tsiku lililonse, zomwe zimaphatikizaponso CAT5, CAT5e, ndi CAT6. Gulu lachitatu linali mtundu wotchuka wa zingwe zomwe zimagwiritsidwa ntchito pa mawu ndi deta kwa zaka zambiri. Pakadali pano, Cat 3 ikugwiritsidwabe ntchito m'makompyuta a mafoni a mizere iwiri, chifukwa nyumba ndi maofesi mamiliyoni ambiri akadali ndi CAT3 yolumikizira mawu. Mwaukadaulo, chingwe cha thunthu ndi chogawa chomwe kampani ya mafoni imagwiritsidwa ntchito kufika kunyumba kwanu kapena ku ofesi kuchokera ku ofesi yawo yayikulu ndi CAT3. Kuyambira kumayambiriro kwa zaka za m'ma 2000, makonzedwe ambiri atsopano a zingwe adamangidwa pogwiritsa ntchito chingwe cha Cat 5e kapena Cat 6, chifukwa chingagwiritsidwe ntchito pa mawu ndi deta popanda kudzaza kwambiri pambuyo pake. Tili ndi zingwe za Outside Plant (OSP) ndi Premise CAT3 zomwe zingakuthandizeni kugawa nthawi yayitali kapena yochepa.

1. Kugwira ntchito kwa chinthu: kupyola zofunikira za mayeso a bandwidth a ANSI/TIA/EIA 568B.2 100MHz;

2. Njira yogulitsira: Gawo laling'ono loyenera la torque limaperekedwa, lomwe lathandiza kwambiri kuti ma transmission agwire bwino ntchito komanso kuti zinthu ziyende bwino;

3. Maonekedwe a chinthu: chivundikirocho chingasankhidwe kuchokera ku PVC, PE ndi LSZH; mitundu yosiyanasiyana ingasankhidwe;

4. Dongosolo lozindikiritsa: chizindikiro cha kutalika kwa chingwe chimaperekedwa kuti chichepetse zinyalala;

5. Dongosolo loteteza: chingwecho chimakulungidwa mu zojambulazo za aluminiyamu ndi waya wothira pansi, kuti

Pewani bwino kusokonezedwa ndi ma elekitiromagineti ndipo perekani chidziwitso chabwino kwambiri

chinsinsi.

Chingwe ichi ndi choyenera kugwiritsa ntchito pafoni, deta, ndi mapulogalamu olumikizirana.
