INTRODUCTION TO FIBER OPTIC TECHNOLOGY – 3 days
This three-day course has been developed with 12 hours of classroom and 12 hours of hands-on skills labs to provide a strong foundation for understanding the basic principles of fiber optic technology. Beginning with a short history of the industry and major growth steps to the state of the art today.
Topics covered include fiber construction and fabrication techniques, numerical aperture, multimode and singlemode transmission theory, intermodal and intramodal dispersion, fiber attenuation, bending losses, fiber scattering mechanisms, fiber splicing and connector termination hardware, system testing and troubleshooting.
Fiber transmission theory is supplemented with hands on training in the safe handling of fibers, removal of the buffer coating, fiber cleaving, mechanical and fusion splicing, connector termination, insertion and return loss measurements, and optical time domain reflectometry.

ADVANCED FIBER OPTIC TESTING AND MEASUREMENTS – 2 days
DAY ONE
You will receive an in depth understanding of the technology and how it has evolved to its present state, nearly at the limits of speed and distance. Learn how fiber is made, how it can be made stronger than steel and how it handles today’s incredible bandwidths. You will understand the causes of insertion and return losses and what determines connector performance. Most importantly you will receive hands‐on training in he proper methods for field testing of installed networks and equipment.
Day one will include the following hands on training
- Learn hands on how to inspect and clean connectors in the field
- Learn how to repair damaged connectors
- Select the right light source for the fiber being tested
- When to use a mandril wrap with your light source
- Measure patchcord losses and identify problem connectors
- Understanding connector endface geometry how it effects return loss
- Measure system end to end loss
- Learn to identify a single mode fiber from a multimode fiber
DAY TWO
Optical Time Domain Reflectometry (OTDR)
The focus will be on OTDR theory and measurements. Students will be presented a thorough overview of current OTDR technology and equipment available. In addition you will learn how to optimize each adjustment of the OTDR to obtain the best possible trace for the desired measurement. Valuable hands‐on training will simulate all aspects of OTDR trace analysis with actual network simulation and real life testing situations.
You will get to do the following hands on experiments
- Simulate a 50Km network with various faults
- Learn to recognize a catastrophic break from an unmated connector
- See the difference between a contaminated connector and a clean one
- Identify a fusion splice from a mechanical splice
- Visualize return loss at each event
- Observe ghost spikes after a reflective event
- Measure fiber attenuation at various wavelengths
- Locate faults or problem areas in a systems
- Understand non-reciprocal losses in systems
