01. Everything starts
in the server

Inside the SFP+/QSFP transceiver, a laser fires infrared light pulses into the optical fibre. Each flash represents billions of bits — the start of a possible intercontinental journey.

02. Light
leaves the rack

Patch panels organise and route hundreds of optical connections simultaneously. Connected to core switches with multi-Terabit capacity, data finds the right path in fractions of a millisecond.

03. Beneath
the ocean

Portugal is a landing point for cables such as MAREA and Ellalink, connecting Europe to the Americas and Africa. Data crosses oceans through glass cores thinner than a human hair, at the speed of light.

Transmission — Inside the Fibre

04. Light at
200,000 km/s

Inside the glass core, photons travel by total internal reflection. With DWDM, dozens of wavelengths coexist in the same fibre, multiplying capacity. Optical amplifiers regenerate the signal every 80 km without converting to electrical — the light never stops.

05. From the POP
to the workstation

The packet reaches you via the best connections and peering with eyeball networks. Wired or wireless — a journey that started in a datacenter laser and ended here, in a few milliseconds.
