2.3 Cable Specifications
2.3.1 Cable classification
XGB Fast Enet I/F module takes UTP cable which is over Cat 5. [Table 2-3] shows cable specifications.
Classification Details Purpose
UTP(or U.UTP)
So called unshielded cable used for
HS signal
ㆍ Max. 200MHz
ㆍ Phonetic + Data + low grade of video signal
FTP(or S.UTP)
Cable with cable core only shielded
solely
ㆍ Max.100MHz
ㆍ Electronic impediment (EMI) and electric stability
considered
ㆍ Phonetic + Data + low grade of video signal(
STP(or S.STP)
Double-shielded structure, pair
shielded and core shielded cable
ㆍ Max. 500MHz
ㆍ Phonetic + Data + Video signal
ㆍSubstitute for 75 coaxial cable
[Table 2-3] Cable class
Remark
1) XGB Fast Enet I/F module does not support AUI (10BASE-5).
2) Twisted paired cable unit (above category 5) takes 100Mbps class hub and if network speed is 10 Mbps, it
can be used with 10Mbps class hub (below category 3). Make sure this to install system.
