Under lab conditions, Telefónica tested symmetrical data transmission using Nokia's fiber glass technology XGS-PON and achieved a transfer rate of 10 GBit/s in both directions.
A downstream of up to 10 GBit/s has already been achieved in the past with this next-generation technology, but the limit for upstreaming data is currently 2.5 GBit/s, only one fourth of the data transfer rate now possible.
Telefónica intends to use the high bandwidths to expand its 5G mobile service network. A well-developed fiber glass infrastructure is the basic requirement for the ultra-rapid fifth-generation network. "The technology for stationary Internet access points has to be further developed to enable new services, competition and future symmetric ultra wideband access. We are convinced that XGS-PON is the perfect choice for meeting the requirements of gigabit bandwidths and supporting the higher symmetrical bandwidths, which are to form the basis of 5G technology in the future", Francisco Javier Fabián, Fixed Access and Real State Director at Telefónica, claims.
