scope:

This part of IEC 61291 describes the optical amplifier command set (OACS) for use in communicating with and controlling intelligent optical amplifiers. These amplifiers can receive and possibly respond to such commands by using resident firmware or may be optical amplifiers controlled by a microprocessor. This standard addresses the structure and content of the command set to control optical amplifiers. It does not cover the physical or hardware interface, which is assumed to exist for communication of this command set to the optical amplifier. The specification of a physical interface will be the subject of a separate Part to be developed in the IEC 61291-6 series. The command set described in this standard is intended to enable a user or host to retrieve the amplifier module's status and/or adjust its settings. This standard lists all of the commands currently defined and supported within the OACS framework. The commands described cover a wide range of applications, and not all commands will be applicable to every amplifier. To determine the supported commands on an OACS compliant amplifier, please refer to the product specification supplied by the manufacturer. All OACS compliant amplifiers support the full set of "universal" OACS commands. Other commands, usually specific to a design or implementation, may support some or all of the "optional" commands.
