Certified Optical Network Associate (CONA)®

About Course

The CONA credential provides a foundational introduction to optical networking, focusing on single-channel and multi-channel systems (CWDM/DWDM) widely deployed in commercial networks. This course covers metro networks, core networks, mobile backhaul, 5G, Fibre to the Antenna (FTTA), Data Centre Interconnect (DCI), NREN, and Satcom links. As Africa’s bandwidth demands explode, certified associates who understand high-capacity optical link design are essential for reliable, high-performance infrastructure.

• Infrastructure Assessment – Evaluate existing fibre quality and suitability for different systems

• Component Specification – Specify and configure transmission link components

• Amplifier Application – Determine when and where optical amplifiers are needed

• Power & Loss Budgets – Calculate optical power budgets and loss budgets for transmission links

• Dispersion Management – Determine when chromatic dispersion compensation (DCM) is required

• Performance Verification – Validate link viability for power levels, CD limits, and PMD levels
