 Fiber-to-the-Antenna (FTTA) Installation and Maintenance Testing
Connect
There are three basic principles that are critical to achieving an efficient fiber optic connection:
y Perfect core alignment
y Physical contact
y Pristine connector interface
Today’s connector design and production techniques have eliminated most of the challenges to achieving core
alignment and physical contact.
What remains challenging is maintaining a pristine endface. As a result, contamination is the #1 reason for
troubleshooting optical networks.

Fiber Connections
Optical connections are made for one of two reasons:
. Completing a System Light Path (TX to RX) Connectors are used extensively throughout optical networks. They
give us the ability to re-configure the network and provision services. If contamination is present in the light
path, system performance will be degraded.
NOTE: Always inspect and, if necessary, clean the contamination from the optical port and optical cable before connecting.
. Connecting a Test Device to Part of the System Test devices are frequently connected and disconnected to
elements of the network. Often, test leads are systematically connected to each port in a network element
in sequence. This duty cycle makes test leads especially prone to contamination and damage. If a test lead is
contaminated, it can quickly spread that contamination through a large portion of the network.
NOTE: Always inspect and, if necessary, clean the contamination from the network port and test lead before connecting.
