Description: This three-day class has been developed with 16 hours of classroom lecture and 8 hours of handson
design exercises to teach attendees to apply critical issues such as customer take rate and density to outside
plant design. This course covers FTTH network field configurations, design benchmarks, and installation
parameters for active Ethernet and PON systems. Attendees will create their own FTTx network designs in
classroom break-out sessions, applying the learned objectives to distributed split, centralized split, home run, and
point-to-point systems.
Prerequisites: This class requires knowledge of fiber optic theory and terminology, as well as field experience,
equivalent formal training such as the Certified Fiber to the Professional (classroom or online) course, or viewing
the Light Brigade Staff Development DVD set.
