Chiyambi cha Zamalonda
Zingwe za foni zokhala ndi mawaya ambiri zimakhala ndi mawaya angapo a mkuwa opindika (monga mawaya 25, 50, kapena opitilira 100) omangidwa mu chikwama chimodzi. Zopangidwira zomangamanga zamalonda ndi zamatelefoni, zimathandiza kutumiza mawu ndi deta nthawi imodzi kudzera pa ma netiweki ambiri, zimagwirizana ndi machitidwe a analogi ndi digito, ndipo zimapereka magwiridwe antchito okhalitsa komanso osasokoneza.
Mawonekedwe
Mphamvu yayikulu: Ili ndi ma peya angapo opindika amkuwa (monga ma peya 25, 50, kapena kuposerapo 100) mu chikwama chimodzi kuti mawu ndi deta zitumizidwe nthawi imodzi.
1. Kulimba: Chivundikiro chake chakunja cholimba (PVC kapena PE) chimateteza ku chinyezi, kusweka ndi kuwononga chilengedwe.
2. Kukana kusokoneza: Kapangidwe ka ma twisted pair kamachepetsa kusokoneza kwa crosstalk ndi electromagnetic (EMI).
