Qorvo has introduced five new low-power four-level pulse amplitude modulation (PAM4) integrated circuits (ICs) aimed at delivering higher performance in data centre and client-side applications. The family of transimpedance amplifiers (TIAs) and drivers gives customers the broadest range of PAM4 options as their migrate their optical networks to 100G to 400G data rates.
As data demand ramps ever higher, researchers are looking to innovative amplifier designs to help transport a broader light spectrum through optical fibres, finds Andy Extance
Duncan Ellis shares his views about the increased focus on automation from network operators, and how the physical layer has so far stubbornly resisted the move
Switching off copper networks where fibre has been deployed is the end game, so why are so few operators doing it, wonders Pauline Rigby
With demand for fibre to the premises increasing, Keely Portway looks at the role training plays in ensuring installation skills remain available to meet this growing demand
