Figure 1 Optical Transceiver
1. View Port Link Status
        Run the command:
            display interface HundredGigE 1/0/29
        It displays link status and operating speed of port 1/0/29.
2. Query Transceiver Identification Information
        Run the command:
            display transceiver interface HundredGigE 1/0/29
        It shows transceiver model, fiber connector type, transmission distance and operating wavelength.
3. Check Transceiver DOM Diagnostic Data
        Run the command:
            display transceiver diagnosis interface HundredGigE 1/0/29
        Note: QSFP-40G-BIDI-SR-MM850 transceiver does not support DOM monitoring function on H3C S6850-56HF switch, real-time temperature, voltage, bias current, TX and RX optical power cannot be queried.
