An out-of-band to optical conversion component is provided that uses a transmit disable signal and a receive loss of signal (LOS) signal built into optical small form-factor pluggable transceiver and cable to pass the out-of-band protocol between serial attached SCSI enclosures. The transmit disable signal, when asserted, turns off the optical output, while the receive LOS signal detects the loss of signal. The out-of-band to optical conversion component sits in line on the serial attached SCSI data traffic and strips off the out-of-band signals from the serial attached SCSI expander so that only data flows over the optical cable. The out-of-band to optical conversion component sends the out-of-band signals to the other enclosure using the transmit disable pin on the small form-factor pluggable transceiver and cable. The other enclosure receives the message on the receive LOS signal and transmit it back onto the serial attached SCSI receive data pair.
