Watch Now: Jon Hjembo and Brian Lavallée Talk Data Centers


By Jayne MillerMay 10, 2018


Growth in global bandwidth consumption won't be slowing down any time soon. It's no surprise that this trend is fueling the need for more data centers and, subsequently, network capacity to interconnect data centers.

As cloud and content providers steer network and data center development, our own Jon Hjembo and Ciena's Brian Lavallée sat down to discuss the latest data center trends driving subsea connectivity growth.

Colocation Highlights

In between talking about where networks converge, content, and cables, Jon covered three different types of colocation markets: low growth, sustained growth, and growth spurt markets.


When it comes to "growth spurt" markets, it's not uncommon for smaller markets to see bursts of growth followed by stagnation. "In places where there's a small established base of colocation capacity, moves by a single operator can have dramatic effects," Jon said.

"In places where there's a small established base of colocation capacity, moves by a single operator can have dramatic effects."

Conversely, in markets that already have a large established base of capacity, there can still be a lot of activity with relatively "low growth" rates. Multiple operators may deploy new sites, but the effect of that growth on the overall established base of capacity may be relatively small.

Looking at sustained growth markets, we see continued growth despite having a well-established capacity base. In massive markets like London, Amsterdam, Dallas, and Hong Kong, even moderate growth rates can indicate significant amounts of ongoing deployments by multiple operators.
