Figure 4 Interface with Blinking Orange Indicator
        When a Moduletek SFP-25G-SR optical module is installed with a fiber jumper connected, the module establishes a normal LINK, and the port indicator lights green.
        The switch correctly identifies module details including type, serial number, wavelength and transmission distance. DOM data can be read normally and stays within the normal threshold range without alarms.
        Note: To view detailed interface, module and DOM information, run:
            show port <port_number>
