When optical modules are deployed on switches, it is often necessary to read their internal data to check operating status—including link connectivity and real-time parameters such as optical power and temperature. Reading module information also helps verify coding compatibility between the optical module and the switch. This article explains how to check the operating status and internal information of optical modules on RAISECOM switches.
        This guide uses the RAISECOM ISCOM2624GF-4C-HI-AC switch paired with Moduletek’s SFP-10G-SR optical module as an example to demonstrate the steps for querying optical module information. For more details about this switch, please refer to: Showcase Of RAISECOM ISCOM2624GF-4C-HI-AC Switch.
1. Check Optical Interface Status
        Run the command:
            show interface <interface-type> <interface-number>
        This command displays the interface speed, module link status (a link status of UP is a prerequisite for normal optical module operation), and basic traffic statistics, which are used for fault troubleshooting.
        Note: <interface-type> <interface-number> refers to the port number where the optical module is inserted, which can be confirmed from the switch panel. If the port number is unknown, omit this parameter; the system will then output information for all interfaces.
2. View Basic Optical Module Information
        Run the command:
            show transceiver information <interface-type> <interface-number>
        This command outputs basic module identification information, including module type, model, transmission distance, wavelength, serial number, and other coded data stored in the optical module.
3. View Optical Module DDM Diagnostic Data
        Run the command:
            show transceiver ddm <interface-type> <interface-number>
        This command displays the Digital Diagnostic Monitoring (DDM) data of the optical module, mainly including real-time diagnostic data and threshold status judgment. By focusing on indicators such as transmit optical power, receive optical power, temperature, and operating current, you can confirm whether the optical module is working normally on both connected devices.
