connecting T1 cables (100-ohm coaxial cables), as shown in Fig. 7.2-7.
Fig. 7.2-7 Connection of T1 Cables
1. Select
T1
cables.
Micro-BTS can be installed outdoors, so PE-sheath T1 cables are used generally.
If common T1 cables are used in an outdoor micro-BTS, PVC pipe should be
added for protection.
2. Lay the T1 cables in order. Keep T1 cables and AC power cables separate with
distance of more than 200mm.
3. When laying T1 cables on a tower, the space between two cable ties should be
less than 0.5m to prevent friction with the tower upon swing of cables and avoid
damage of T1 cable sheath.
