Temperature -
Most multi-pair PVC 24 AWG twisted pair cables
typically have an attenuation of approximately 8 to 10 dB/100 m (330
feet) at 20
°
C (68
°
F). The attenuation of PVC insulated cable varies
significantly with temperature. At temperatures greater than 40
°
C
(104
°
F), it is strongly recommended that you use plenum rated cables to
ensure that cable attenuation remains within specification.
2.1.2
Coaxial Requirements
The coaxial requirements to use the CTP100T adapter are as follows:
•
A 50-ohm RG-58 A/U type coaxial cable must be used when
making up thin-net cable segments.
•
The thin-net cable segment connected to the BNC port on the
CTP100T adapter must be no longer than 100 meters (330 feet) in
total length.
•
The far end of the thin-net cable segment must have a 50 ohm
terminator.
•
A maximum of 10 nodes may be connected to a thin-net coaxial
segment on the CTP100T adapter. These taps must be at least 0.5
meters (1.65 feet) apart.
Warning:
For safety, one and only one end of any thin-net segment
should be connected to earth ground. Connection to earth ground
at more than one point on the segment may allow for the
occurrence of dangerous ground currents. The BNC port of the
CTP100T is not internally connected to earth ground.
