Item
All cables are connected securely and reliably. Pay special attention to the
communication cable connections and cable connections at the bottom of the
cabinet.
The cables are neatly and tightly bound. The cable ties are evenly spaced and face
the same direction.
Different types of cable, such as the power cable, ground cable, feeder, optical cable,
E1/T1 cable, and FE cable are separately bound.
The cable layout facilitates maintenance and future capacity expansion.
All the labels at both ends of the cables are legible.
The extra length of the indoor cable ties is cut, and the cut surfaces are smooth
without sharp edges. The extra length of 3 mm to 5mm of the outdoor cable ties is
reserved when the cable ties are cut.
The idle port that no cable is connected to is properly protected.
The connectors of the RF cables are fixed in position to avoid false connection that
may cause an abnormal voltage standing wave ratio (VSWR).
