Many optical spectrum analyzer (OSA) users need to decide what type of OSA is required to analyze these signals in the field: traditional grating-based OSAs or a new generation of OSAs? There have been some comments that operators should select the high-resolution OSAs, which provide higher resolution bandwidth (RBW), for optimal analysis. Is this hype really founded?

Voice over LTE (VoLTE) is the talk of the town. Everyone in the industry is rushing to deliver VoLTE and the rich communication services that will tag along. However, many seem to profoundly underestimate the complexity underlying this new technology. VoLTE is not an upgrade of a previous technology–it’s a whole new game when compared to the good ol’ copper wires.

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 In the field, I see a lot of variation in the testing regimes used and every day I am surprised to come across outdated and highly inefficient practices to address today’s Ethernet services.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