Designed for all skill levels, this course provides all
the information required to operate confidently and
Assess the quality of an optical fibre
transmission link.

This course will provide a comprehensive awareness of a
variety of commonly used commissioning techniques and
tooling, including tri-band OTDR testing. Attendees will also
learn techniques to develop carrier-approved commissioning
reporting, including nbnTM and TelstraTM.
