This course provides an introduction to optical networking and the types of systems that are in widespread commercial deployment. It focuses on networks that use either a single channel per fibre, or multiple channels using CWDM and DWDM technology, providing typically up to 10 Gb/s per channel and up to 80 channels per fibre. This may include metro or core networks, ‘mobile backhaul’ or ‘dark fibre’ links and long haul systems that also use fibre amplifiers.
Cost and compatibility can make a compelling case for pushing 100Gb/s bandwidth over a single optical channel, both as individual links and supporting 400Gb/s Ethernet, finds Andy Extance
Robin Mersh takes a look at how the industry is creating next-generation optical access fit for 5G
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
