Welcome to Issue 88 of SubTel Forum, our Subsea Capacity edition. This issue delves into the burgeoning demand and developments in subsea telecommunications capacity. As the industry experiences a surge in activity, with full order books and extensive kilometers of cable to manufacture and install, we explore the implications of this growth. Key articles include a global capacity outlook by Kieran Clark, an analysis of whether a terabit is sufficient by Derek Cassidy, and insights into optical designs for greater power efficiency by Alexei Pilipetskii and colleagues. As companies navigate this dynamic landscape, the question remains: how long will this growth continue? Join us as we explore these themes and more in this edition.
