Connecting Fiber Cables

To connect fiber cables to the transceiver:

1.Remove the plastic protection caps from the fiber optic port only when ready to install cables. Transceiver ports that are not in use should remain capped.

2.Ensure that transmit and receive cables are clearly marked or color coded and are connected to the appropriate ports on the Transceiver.

3.Ensure the cables have been properly cleaned with an appropriate fiber optic cleaning solution before installation.
