Abstract
An optical module switch device includes a first serial-parallel-converter coupled to first signal-lines coupled to optical modules, and second signal-lines, a number of the second signal-lines being greater than the first signal-lines thereof, and configured to transmit/receive first signals at a first transmission-rate to/from the optical modules by using the first signal-lines, respectively, a second serial-parallel-converter coupled to second signal-lines coupled to the first serial-parallel-converter, and third signal-lines, a number of the third lines being greater than the second signal-lines thereof, and configured to transmit/receive second signals at a second transmission-rate lower than the first transmission-rate to/from the first serial-parallel-converter by using the second signal-lines, respectively, and a switch circuit coupled to the third signal-lines, and configured to transmit/receive third signals at a third transmission-rate lower than the second transmission-rate to/from the second serial-parallel-converter by using the third signal-lines, respectively, to perform routing processing based on the received third signals.
