Data Transmission System Uses 4-Core Optical Fiber, Sets Distance Record TOKYO, July 22, 2021 — A research team led by Benjamin J. Puttnam at the National Institute of Information and Communications Technology (NICT) reported that it transmitted data over a distance of more than 3000 km (1860 miles) at a rate of 319 Tbit/s and a transmission bandwidth of greater than 120 nm, across the S-, C-, and L-bands. The team used a 4-core optical fiber with a 0.125-mm outer diameter to transmit the data, setting a record for data transmission over an optical fiber with a standard cladding
