In conversations with hyperscalers and communication service providers (CSPs), one trend stands out: data center interconnect (DCI) remains the fastest-growing part of the network, with annual growth exceeding 50%. With analysts like Vlad Galabov at Omdia indicating that data center capital expenditures could surpass $1 trillion in 2030, the data center construction boom shows no signs of slowing.
The quest for real estate and power is driving data center builds into more diverse geographies than ever before. Around the globe, one can see existing data centers expanding and new ones being built nearly everywhere.
So, how can data center owners and the network operators that provide wholesale transport services cost-effectively meet today’s DCI demands while keeping up with tomorrow’s rapid growth? Three key technologies will help define the path forward.
Coherent Pluggables
While embedded optical engines that deliver 800 Gb/s or 1.2+ Tb/s wavelengths remain the workhorse of optical transport networks, coherent pluggables are the rising star. 800G ZR/ZR+ coherent pluggables are now available and ramping to meet rapidly growing demand.
Thanks to deep vertical integration, advanced 3nm digital signal processing (DSP) geometry, and sophisticated modulation techniques previously only available in sled-based embedded engines, industry-leading 800G ZR/ZR+ coherent pluggables deliver 800 Gb/s wavelengths up to
