The Backbone of the Global Telecommunications System

Wavelength services are the backbone of the global telecommunications system, providing high-speed, dedicated bandwidth for businesses across the world. At GCX, we operate the world’s largest private subsea network with end-to-end connectivity up to 400G, offering a variety of routing options to meet the increasing demand for bandwidth.

High-Speed Bandwidth on a Privately-Owned Network

Our Wavelength Services are built on our own privately-owned subsea network, stretching from New York to Tokyo via the Atlantic, Europe, the Middle East, India, and South East Asia. Our network includes several subsea cables, including FA-1, HAWK, FALCON, FEA, and FNAL, providing our clients with a diverse range of routing options.

Our network offers Wavelength services up to 400Gbps, making it the network of choice for Telcos, OTTs, data center operators, and enterprises looking for high-capacity dedicated connectivity within the Mediterranean, Middle East, Asia, or across the Atlantic. And because our network is privately-owned, upgrades and bespoke routes can be handled swiftly and efficiently.

Key Building Blocks of the Digital Ecosystem

Our network has been transformed to connect the world’s digital ecosystems at speeds of up to 400Gbps (and beyond). By interconnecting to key locations across our next-generation global network, we have ensured that we are in all the locations our clients need us to be in, offering reliable, high-capacity, end-to-end connectivity.

Our network provides connectivity from APAC to EMEA to NA, all via our own privately-owned network.
