Grounding the Buried Fiber
The buried fiber drop cable to the subscriber premises used in this application can be one of
the following:
• Non ‐ armored: the non ‐ armored fiber drop cable has a metal strand for locating purposes.
Skip this procedure if the fiber drop is non ‐ armored.
• Armored drop: when the fiber drop cable is armored, grounding of the cable sheath is
required at the ONT. A UL Listed ground shield connector is used to ground the armored
fiber. If the fiber drop is armored, complete the following steps to ground the fiber:
1. Install the ground shield connector assembly on the fiber drop cable.
2. Place black electrical tape tightly around the connections to prevent water intrusion and
corrosion.
3. Attach a ground strap to the ground termination lug.
Ground Wire Connection
WARNING
!
Extreme care must be taken when attaching the ground connectors to the
utility (earth) ground rod. If the ground is interrupted or disturbed in any
way, an unsafe condition will exist. Refer to the National Electrical Code
(NEC) and state/local codes for details on grounding requirements.
Complete the ground connection by completing the following steps:
1. Remove the rubber grommet from the housing (see Step 1 in Figure 12 ).
2. Insert a 6 AWG solid copper ground wire through the rubber grommet (see Step 2 in
Figure 12 ). Terminate the ground wire at the ground bar as shown in Figure 13 on page
25.

3. Reinsert the rubber grommet with the ground wire into the ONT housing (see Step 3 in
Figure 12 ).
4. Ensure the ground wire is routed as shown Figure 13 on page 25.
