Crosslake Fibre has achieved another major milestone: the CrossChannel Fibre subsea cable is now carrying live traffic, providing modern, direct connectivity between Slough, UK and Paris, France. This is the first subsea route across the English Channel in two decades.
The system includes a 149 km subsea span from Brighton to Veules-les-Roses, within a ~550 km total route. It delivers ultra-low latency (< 5.5 ms round-trip) and features physically diverse routing for higher network resilience. Key infrastructure includes the landing in Brighton, integration at Equinix LD4 in Slough, and connectivity to Interxion PAR3 / Equinix PA7 in Paris.
The service offers dark fibre as well as scalable capacity via advanced optical technology from Ciena, along with real-time capacity scaling via MCP and Liquid Spectrum tools. Initial capacity is set between 600–800 Gbps with the flexibility to grow with demand.
