Roshene McCool and Matthew Guinan advise how operators can meet the connectivity distribution and densification challenge

Massive connection point distribution and optical fibre cable densification is occurring in access and data centre networks. Each connection point needs an optical fibre, so the number of fibre strands needed to deliver network connectivity is spiralling upwards, while space and physical pathways to route these fibres is fixed or rapidly being consumed.

Mathieu Bergont and Francois Couny look at the challenges that come with PIC testing and measurement

Photonic integrated circuits (PIC) are already deployed in commercial products and are steadily replacing traditional optical subassemblies, providing an improved level of miniaturisation while reducing electrical consumption. Data center interconnects (DCI) currently drive the demand for PIC, but 5G is also expected to benefit from PIC in the near future, indirectly affecting PIC testing and measurement requirements.

Ana Pesovic discusses the three core elements required in creating a smart city

For centuries, humanity has looked for new ways to build smarter cities; ways that improve city operations, grow the economy and create a better place for people to work and live. From the aqueducts in Rome to the more recent technology innovations that help simplify the challenges of urban life, cities are, and have been, getting smarter throughout history.

Over the last year, you may have heard proponents espouse the benefits of OM4+ multimode fibre. For instance, they claim it is better for single-wavelength applications, and it’s comparable to OM5 for multiwavelength application support. While OM4+ may have some useful attributes, which vary from company to company, that variation is a clue to the fact that in all cases it is proprietary, meaning it is not standardised. Essentially, the public is being asked to take OM4+ proponents at their word. As New York Yankees legend Yogi Berra once said, ‘It’s like déjà vu all over again’.
