Appendix F Engineering labels for cables

Engineering labels are affixed to both ends of the cables to identify the physical positions of cables on
different devices. Labels on the cables facilitate correct and orderly connection of cables, and easy
maintenance after the installation.
NOTE:
If there is special requirement of the equipment on the description method of the labels, the labels should
be printed accordingly. However, this must be stated in the self-check report.

Type and shape

There are two types of engineering labels, specialized for the power cords and signal cables respectively.
The power cords include the AC power cords and DC power cords (excluding the power cord that
connects the distribution box and the cabinet). The signal cables include external cables of alarm box,
Ethernet cables, optical fibers, trunk cables and subscriber cables (excluding the antenna feeders).
