Fujitsu Laboratories Ltd. today announced that it has developed the world's first optical transceiver circuit in which multiple circuit lanes can be laid out in parallel, paving the way for higher-capacity data transmissions between CPUs in future servers and supercomputers. Re-timer circuits handle the waveform and noise reduction needed for high-density transmitter circuit and high-speed transmission signals. Because individual re-timer circuits are susceptible to coupling from adjacent ones, it has been difficult to lay them out in close proximity to each other.
