The three factors that determine spectral efficiency
For many fibre applications, spectral efficiency is a key performance criterion. This white paper focuses on why spectral efficiency matters, how the relationship between wavelength capacity-reach and spectral efficiency has changed, and the three key factors determining spectral efficiency.
The Optical Fiber Communication (OFC) conference and exhibition took place from 6-10 March. Here is a roundup of just some of the technology and product announcements, demonstrations and industry news from the event.
The European Commission has proposed a comprehensive set of measures to ensure the EU's security of supply, when it comes to semiconductor technologies and applications.
This white paper explores the component-level and systems-level innovations enabling ROADM evolution along seven vectors related to wavelength capacity-reach, fibre capacity, add/drop and degree flexibility, footprint, openness, operations and manageability, and network availability.
