Yintoni iCATVinkquboWiring Njani?

 

 

CUkungeniswaNindlela yokubala ye-etwork yeeNkqubo zeNtambo zeCATV:

Le ndlela ichazwa njenge: bonke abasasazi bamasebe abaphantsi bagxunyekwe kwigumbi elibuthathaka langoku, kwaye intambo yokuhamba kanomathotholo ibekwe ngokuzimeleyo ukusuka kwisiphelo ngasinye somsebenzisi (isokethi) kwigumbi langoku elibuthathaka elihambelanayo nokunxibelelana nomhambisi wesebe.

 

Inxalenye ethe tyaba ye Ikhefu Cnako RG6, the calculation method of cnako usage:

 

Average cnako length = (horizontal distance of the farthest user terminal + horizontal distance of the nearest user terminal)/2+2H (H——floor height)

 

Actual average cnako length = average cnako length × 1.1+ (termination tolerance, usually 3)

 

Total number of cnakos required = total number of user terminals x actual average cnako length (m)

 

Phawula:Umgama othe tye kweyona ndawo ikude kunye nendawo ekufuphi yomsebenzisi ngowona mgama ukusuka kwibhokisi yokuhanjiswa komgangatho ukuya kwesona sikhululo sikude sikufutshane nakwezona zikufutshane, kubandakanywa owona mgama wendlela ethe tye. Ukuba ibhokisi yokuhambisa esemgangathweni imiselwe kwimigangatho emininzi, umphakamo ohambelana nayo kufuneka ubandakanywe.
