Outdoor copper Cat5e Ethernet cable
Outdoor Cat5e cable is used for all connections that terminate outside the building. For example,
connections between the ODU, surge suppressors (if installed), UGPS receivers (if installed) and the
power supply injector. This is known as a “drop cable” (
Figure 27 ).
The following practices are essential to the reliability and longevity of cabled connections:
• Use only shielded cables and connectors to resist interference and corrosion.
• For vertical runs, provide cable support and strain relief.
•
Include a 2 ft (0.6 m) service loop on each end of the cable to allow for thermal expansion and
contraction and to facilitate terminating the cable again when needed.
• Include a drip loop to shed water so that most of the water does not reach the connector at the
device.
•
Properly crimp all connectors.
• Use dielectric grease on all connectors to resist corrosion.
Order Superior Essex type BBDGe cable from Cambium Networks ( Table 43 ). Other lengths of this
cable are available from Superior Essex.
