Essential GPON and FTTx networks

A 5 day
HANDS ON
training course

Essential GPON and FTTx networks training course description

Designed to benefit those requiring an in depth knowledge of the principles and applications of Ten Gigabit and Gigabit Passive Optical Networking and Fibre to the X in NG Networks applications and their associated equipment, its flexibility and function within a modern transmission network.
Using an effective mix of “hands on” equipment instruction and correlation to theory based learning the delegate will gain a complete understanding of the equipment and the tasks to be undertaken in a real life situation.

Key outcomes from this course

By the end of the course delegates will be able to:
  • Compare PON/FTTx systems.
  • Explain network elements and designs.
  • Support applications and network interfaces.
  • List circuit provisioning and bandwidth requirements.
  • Understand upstream & downstream issues.
  • Describe headend & network elements/OLT-ONT.
  • Perform network testing with OTDR test sets.

Essential GPON and FTTx networks training course details

Who will benefit:
Anyone working with GPON and FTTx.
Prerequisites:
Introduction to data communications and networking.
Duration:
5 days

Training approach

This structured course uses Instructor Led Training to provide the best possible learning experience. Small class sizes ensure students benefit from our engaging and interactive style of teaching with delegates encouraged to ask questions throughout the course. Quizzes follow each major section allowing checking of learning. Hands on sessions are used throughout to allow delegates to consolidate their new skills.

Why Choose Us

SNT trainers score an average of over 90% on the three main areas of:
  • Ability to teach
  • Technical knowledge
  • Answering questions
“Excellently presented by a very knowledgeable and enthusiastic trainer.” P.D. General Dynamics

We limit our maximum class size to 8 delegates; often we have less than this. This ensures optimal interactivity between delegates and instructor.
"Excellent course. The small class size was a great benefit…" M.B. IBM

We write our own courses; courseware does not just consist of slides and our slides are diagrams not bullet point text. A typical chapter provides clearly defined objectives with a chapter overview, slides with text underneath, a quiz at the end to check the learning of the students. Hands on exercises are at the end and are used to reinforce the theory.
