How to Install a Fiber Optic Modem?



Steps to install a fiber modem:


  1. Hook up the modem with the female DB25 connector found on the device that will be used to run the modem. If the power is not furnished via the DB25 connector, then proceed to Step 2. If it is provided through the DB25 connector, then move on to Step 3.


  1. Insert a wall power supply into the nearest wall outlet. Join the plug attached to the end of your power supply's wire with the modem's power input port. You'll find this port adjacent to the fiber connectors.
