T-Mobile Austria has conducted 400G optical transport tests within the existing network, resulting in 475km no-bit-error transport of 10G/100G/400G (16QAM) hybrid DWDM signal.

ZTE says the test included smooth capacity upgrade of the existing 10G/100G DWDM network, by implementing 400G between Vienna and Graz, extending the link capacity. The capacity increase is important for future network evolutions towards new technologies, like cloud operation and big data.

Faster data connections and more capacity for different services, like high-speed internet, video conferencing, TV and gaming, etc. are the main benefits to customers of T-Mobile Austria.

T-Mobile Austria, the second-largest mobile operator, performed the 400G (dual-carrier 16QAM) 475km ULH transport (Vienna-Graz-Vienna) adjacent to the 10G and 100G channels. The demo showed performance efficiency, seamless upgrade and advanced future evolution of the existing network to 400G and beyond-400G.

The software-defined optical modules of 400G boards can accommodate the metro, long-haul and other scenarios by adjustment of modulation modes and spectrum.

ZTE is the supplier of existing DWDM network. ZTE’s optical network products accounted for 13 percent of the global market share, ranking No. 2 in the world.
