However, in geographical areas that have above normal lightning activity, Airspan
can supply an optional DC surge protector adapter (see Part II, Chapter 18, "Power
Cabling").
2.4. Cabling
Warning: Cables with exposed ends (i.e. not yet crimped) should be covered
with protective polythene bags during external cable installation processes.
Warning: Disturbance of cables on an In-Service exchange can cause loss o
f
service. Extreme care must be taken when installing cables at any customer o
r
subscriber premises.
Warning: The standard maximum cable length between the outdoor radios and
indoor switch/hubs (IDU/ODU) is 100 meters using the standard CAT 5 cable.
However, you can extend this cable to up to 300 meters. See Appendix F,
"Extending IDU/ODU Cable Length".
2.4.1. Considerations
The following issues should be considered during cabling at the ASWipLL Base
Station and customer premises:
 Cable routes are to be defined in a site-specific documentation.
Note: A minimum separation of 200 mm should exist between power and data
cables. However, it is permissible to allow these cables to cross each other a
t
right angles.
 Observe recommended minimum bend radii when installing copper cables.
Wherever a cable changes direction, ensure that it does so in a smooth curve
with a radius of at least 50 mm to prevent damage.
 Plastic ties and wraps are to be used to secure cables at regular intervals to trays,
guides, and mounting pole/bracket. Ensure all trimmed ends are disposed of
safely and at regular intervals.
