Chinese team claims 3.2 Pb/s optical-fiber transmission record

A Chinese research team reports transmitting data in real time at 3.2 petabits per second over a 10.3-kilometre, 24-core optical fiber. The demonstration combined multiple wavelength bands and spatial-division multiplexing; the researchers say its hardware architecture is commercially compatible, though the supplied reports do not establish commercial deployment.

• The team reported a real-time, bidirectional transmission rate of 3.2 petabits per second using a 24-core optical fiber.· 1 source
• The test used 10.3 kilometres of fiber and combined S, C and L wavelength bands with space-division multiplexing.· 1 source
• The researchers say the result exceeds their earlier 2.5 Pb/s demonstration; reports describe the increase as roughly 28% or almost 30%.· 2 sources
• The team says it used commercially compatible hardware architectures. The reports describe potential applications in network capacity, but do not report that the system has been commercially deployed.· 2 sources
