Last month in an air conditioned switch room of a UK-based mobile operator, I joined one of our clients trying to commission an Ethernet backhaul circuit. Despite the equipment manufacturer’s claims of a plug-and-play solution, this particular link didn’t want to “play”. The air-con was obliged to work a little harder as both the frustration levels and temperatures rose.

The telecom industry seemingly has a firm grasp on 40G/100G coherent detection systems, with deployments extensively deployed in many regions across the globe. Coherent systems are heralded as an impressive solution to compensate for Polarization Mode Dispersion (PMD), thanks to advanced algorithms and advanced modulation formats. But do they actually deliver the results?

Customers have little patience for poor coverage. This is when churn comes in play and becomes the biggest challenge for mobile network providers. In order to meet their SLAs, they need to provide:High speed connections (LTE/LTE-A), good and constant coverage as well as rapid service to their entire subscriber base. Evolution in the RAN technology and fronthaul networks aim at overcoming these challenges.

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 In the field, I see a lot of variation in the testing regimes used and every day I am surprised to come across outdated and highly inefficient practices to address today’s Ethernet services.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.

Two of the most important applications of NFV—the virtualizing of EPC (evolved packet core) and IMS (IP Multimedia Subsystem)—demand especially high and predictable performance and stable, seamless interconnection between virtual and physical networks.

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.
