Technological advances to aid the increasing demand for bandwidth, on the path towards the terabit network, should lead to optical signals that are flexible and adaptive, like water, argues Dr Maxim Kuschnerov and Dr Yin Wang
Oclaro's Adam Carter and Dan Tauber examine which modulation schemes – DMT, PAM4 or coherent – are likely to prevail in the race to higher-speed transmission for more cost-sensitive links
Scaling the capacity delivered by optical systems is becoming increasingly difficult, even as data traffic continues to grow exponentially. Pauline Rigby investigates new techniques that could postpone the inevitable ‘capacity crunch’
Geoff Bennett examines the evolution of coherent super-channels and how the use of software programmable modulation formats gives operators new options for network optimisation
With providers facing the challenges of keeping up with internet traffic growth, terabit-scale systems are on the rise, Robert Roe writes
To exploit machine learning and artificial intelligence, optical transmission systems require greater automation, finds Andy Extance
Roshene McCool and Matthew Guinan advise how operators can meet the connectivity distribution and densification challenge
John D'Ambrosia explains how various Ethernet standards developed in IEEE 802.3 over the past decade are enabling a myriad of products to find their way into deployment throughout the Ethernet eco-system
Mathieu Bergont and Francois Couny look at the challenges that come with PIC testing and measurement
Geoff Bennett outlines three myths surrounding optical capacity, and how they can be dispelled
