Q

Because fiber drops come in pre-made lengths, you may have to store excess fiber in the ___.

A

The Pedestal or vault.

11
Q

If the Status LED on the FTTP RFoG ONU is red, this means.

A

Optical Power Input is poor

12
Q

During a FTTP installation, what are the two bonding options inside of the ONU enclosure?

A
  1. Install a ground block in the coax connected to the RF side of the ONU.2. Eliminate the ground block and connect the ground wire to the ground lug on the ONU.
