Nokia and Vodafone announced the successful testing of a new passive optical network (PON) technology that enables speeds up to 100 Gbps. This is several times faster than the fastest modern networks that are available today.
The tests were carried out at the Vodafone laboratory in Eschorn, Germany. The 100 Gbps speed was achieved using the existing optical line with a maximum speed of 25 Gbps in combination with special digital signal processing (DSP).
Nokia says that once this DSP technology is adopted, it will be relatively easy to scale to 50 or 100 Gbps, and such speeds may be commercially available in the second half of this decade.
The prototype tested in this test is also the first application of flexible bit rate in a passive optical network. This technology groups fiber optic modems with similar network characteristics, such as loss or dispersion, to reduce network latency and cut power consumption in half. Such technology could ultimately help build more scalable networks to deal with congestion during peak hours.
Of course, it will take time for such speeds to become available to users, but successful tests confirm that scientists are close to implementing the plan.
