KDDI transmits optical data 1,000km at 100Gbps without correction

2 May 2008

KDDI Corp’s R&D Laboratories unit has reportedly developed an optical transmission technology capable of transmitting data at speeds of up to 100Gbps over a regular Ethernet network at distances of 1,000km without the need for signal correction. Current Ethernet protocols have been developed to allow data transmissions of up to 10Gbps by using a bundle of ten lines and a set of ten transceivers. AsiaPulse reports however, that KDDI’s research arm is using multiplexing technology based on orthogonal frequency-division multiplexing (OFDM) to send data at 100Gbps without the problem of faster signal attenuation, meaning that the transmission does not require signal correction.
