ZTE completed a field demonstration of a 8x 216.4 Gbps WDM transmission through a 50GHz optical spectrum grid.
The demonstration utilized patented ZTE high-frequency technology to accomplish a 200 Gbps polarization multiplexing QPSK signal transmission at 50GHz through 1,750km of standard single model fiber optic cable.
ZTE said its trial established a 25% increase in spectrum efficiency and an increase in transmission efficiency, proving that a 200G system is possible.
