Fiber-optic Installation Seminar

Course Description

Optical infrastructure is the paradigm of the day to provide roads of glass, satisfying the ever-growing demand for data-rates and bandwidth. While coaxial infrastructure close to the customer still serves its purpose and will continue to do so for a few more years, newly installed infrastructure should certainly be optical fiber.

Fiber optics come with a different set of cables, equipment and operational specifications. Professional technical competence can only be achieved by understanding the operational principles behind optical communications, as well as by learning the everyday handling and troubleshooting of optical equipment and the working with optical fiber.

AXP optical fiber training seminars are designed to deliver precisely this knowledge.

  • Fiber training seminars can be modified to the customer’s specific needs.
  • Custom modules designable
  • Onsite- and online presentation
  • Presentation in English or German

Target Audience:

This course is recommended for both independent cable and multi-system operator (MSO) engineering and technical professionals, including mid- to senior- level technicians; maintenance and installation technicians; and technical operations (TechOp) personnel.

Course Length:

7 Modules of ca. 2 hours each

Course Modules:

  1. Fundamentals of optical communications (Fttx, PON)
  2. Planning and design of optical networks
  3. Deployment of optical technology in the field
  4. Installation of optical fiber and equipment
  5. Measurements on optical networks
  6. Troubleshooting optical networks
  7. Advanced optical solutions (Fiber deep, DAA, EPON, GPON, XGS PON)
