Now, network operation managers need to be able to rapidly deploy a plethora of new high-quality services. In turn, field engineers are faced with the need to complete a wide array of tests to verify critical transport parameters which assure compliance and quality. In the field, I see a lot of variation in the testing regimes used and every day I am surprised to come across outdated and highly inefficient practices to address today’s Ethernet services. Let’s take a few moments to understand how to address the challenges of Ethernet Testing 3.0.

40G or 100G coherent systems on long-haul dense wavelength-division multiplexing (DWDM) networks provide great benefits that even go beyond “simply” boosting your bandwidth. However, they also bring about new test and measurement challenges, particularly for optical spectrum analyzers (OSAs)—test instruments that are vital to optimal DWDM system commissioning and troubleshooting.

Are you in charge of a mobile backhaul network? Are you faced with dispersion challenges that are increasing your bit error rates (BERs)? Do you know what dispersion tests work best for mobile backhaul deployments?Although dispersion testing was traditionally performed in metro and core networks, it is now, more than ever before, moving closer to the network edge in mobile backhaul deployments or client-side rollouts. But why?
