Bell Labs Tests 400Gbps Fiber Speed

Bell Labs Tests 400Gbps Fiber Speed Bell Labs recently found a new method that can transmit at high speeds at extreme distances, reaching 400 Gbps in tests. The experiment draws on the basic concept of a similar silencing headset: Researchers send two beams of light in opposing places because of overlapping of two lights, which can avoid signal distortions in the medium, and long range.

Using this principle, Bell Labs achieved a 400Gbps speed on the 7594-mile fiber test under the condition of ocean testing, while maintaining the high signal strength and high transmission speed of the fiber. In the near future, we will see the dual-optics technology put into practice. Can the Internet giant Alcatel-Lucent completely free broadband?
