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.
CableLabs is spearheading efforts to develop a proposal that uses coherent optics to dramatically boost the capacity of hybrid fibre coaxial networks, reports Andy Extance
Systems vendors are using intelligent software to squeeze more performance from optical networks. Pauline Rigby reports on developments at OFC 2017
