Japanese Team Targets 24-Tbps Optical Fiber By 2014
Credit: SuperComputingOnline.com
The Japanese government is sponsoring a project to boost data transmission speeds over optical fiber, with a target of 400 Gigabits per second per channel by 2014. Researchers at Fujitsu, NTT, and NEC will collaborate to combine 60 channels using the new technology, with hopes of achieving a total data transmission rate of about 24 Terabits per second over a single optical fiber.
The researchers plan to advance current techniques for multiplexing and modulation of signals, and address the degradation of optic signals over large distances. The companies will seek to make the new network technology as adaptable as possible to handle sudden fluctuations and changes in the network. A major goal is to reduce power consumption to less than half of that used by current technologies.
Fujitsu, NTT and NEC also are focused on developing a single device that can both modulate and demodulate traffic, for more overall network flexibility. Part of the aim of the research is to establish networks that are fast and flexible enough to quickly recover when base stations are knocked out by large-scale natural disasters.
