Gen 6 networks will reach 128Gbps by combining four 32Gbps connections into what logically looks like one, FCIA president Mark Jones said. Those four links can take the form of separate wire strands in a copper cable or separate wavelengths of light in an optical fiber, he said.
The upcoming specification includes advancements for reliability and energy efficiency as well as speed, FCIA Chairman Skip Jones said. Gen 6 adds a standard form of forward error correction, which predicts transmit errors and corrects them without the need for time-consuming retransmission. For power saving, the standard includes a way for optical connectors to dim their lights when there's no data to transmit, then immediately come back to full strength, he said.
