Multi-fibre connectivity such as MPO is playing an increasingly important role in modern fibre networks as higher-density architectures are adopted to meet growing capacity demands. While the technology has existed for many years, its use is accelerating alongside new applications and deployment models. In this eBook, VIAVI Solutions and US Conec share insights from a survey of over 300 fibre network professionals involved in specifying, installing, and operating MPO-based networks. The report highlights key challenges, practical considerations, and emerging trends, including the move towards Very Small Form Factor (VSFF) connectivity.
