In one embodiment, a 10 Giga-bit Ethernet conversion system is provided that is operable to be inserted in 10 Gigabit optical fiber Ethernet systems, wherein each optical fiber Ethernet system includes an electrical-to-optical interface presenting electrical signals to an optical interface for converting the electrical signals to optical signals, the electrical signals being organized into a plurality of channels, wherein each channel carries Ethernet idle characters between data frame transmissions. The system includes: a transmission alignment circuit operable to detect a unique synchronization code (SC) in the idle character transmissions in the channels, the transmission alignment circuit operable to delay each channel by a variable delay period determined by the period between detection of the SC in the channel and the detection of the last SC in the remaining channels such that the channel having the last SC is not delayed with respect to the other channels, the transmission alignment circuit thereby forming a plurality of aligned channels; and an encoder for modulating each aligned channel into an electrical multiple-bit-per-baud signal, the encoder thereby providing a plurality of multiple-bit-per-baud signals corresponding one a one-to-one basis with the aligned channels.
