ZTE has demonstrated a fiber-optic network is the next generation.
In the test system used technology WDM (Wavelength Division Multiplexing) - Multiplexing Wavelength Division. It allows you to simultaneously transmit multiple data channels on a single optical fiber at different carrier frequencies. WDM significantly increases the throughput of the link. It is reported that ZTE data transferred immediately to eight channels, each of which provided a speed of 216.4 Gbit / s. As a result, the combined capacity of connections reached 1.7 Tbit / s. Tests were conducted using standard single-mode fiber-optic cable. The distance between the sender and the recipient was 1750 km. For information on when to expect the appearance of commercial networks with a capacity of 216.4 GB / s per channel, not reported.
