3.17.4 Fiber Identifiers
The Photodyne 8000XG fiber identifier (Fig. 3.59) is designed for fast
accurate identification and traffic testing of fiber-optic lines without
cutting the fiber line or interrupting normal service. Ideal for use dur-
ing routine maintenance and line modification, this small handheld
unit can be used to locate any particular fiber line, identify live fibers,
and determine whether or not traffic is present. Features of the
8000XG include:
• Light weight, portability, and battery operation
• Automatic self-test after each fiber insertion
