Nokia and Telefónica are already testing symmetrical 20 Gbps FTTH fiber connections

Nokia and Telefonica have announced the first tests of 25G PON technology to take a leap in the fiber speeds that they currently offer to their customers. In these first tests They have managed to reach speeds of up to 20 Gbps symmetric.

25G PON is capable of working with current FPON and XGS-PON technologies, so it would not be necessary to deploy new cables or infrastructure to be able to offer symmetrical 20 Gbps. We talked about almost 2.5 GB/s download and upload speed a through FTTH, figures that may not be very successful in the domestic market at the moment, but that can be very useful in certain businesses and specific uses where high bandwidth is required.

Telefónica specifically mentions new technologies such as the “metaverse”, making 25G PON prepare their networks for the speed and low latency needs that virtual worlds will demand as they evolve to systems of higher quality and complexity.

To achieve these 20 Gbps with 25G PON, Nokia has used devices with its Quillion chipset, demonstrating that they can live with current technologies for future deployment. Its theoretical maximum speeds are 25 Gbps symmetric and 25 Gbps download and 10 Gbps upload in asymmetric mode through fiber optics.

At the moment there are no estimated dates for the arrival of the final deployment,
