This course provides attendees with skills to confidently test and fault-find
NBN’s Fibre Optic network across the three different
architectures: TFN, DFN and LFN / MTLFN.
This course is designed for individuals with minimal
experience and ensures that learning outcomes can be applied
immediately to field activities using our advanced real-world
and hands-on learning environments.
On completion, learners will have the confidence to test
and commission the nbnTM Optical network to the published
standards using modern equipment and techniques.

  discussed

Evaluating overall Link Quality

• Understanding network testing thresholds
• Calculating loss/attenuation budgets
• File naming conventions and trace file formats/structure
