Can I view the optical module types of switch and the receiving and transmitting power of the optical modules

You can use commands to view the information.

To view the type of an optical module inserted into an optical interface, run the display interface interface-type interface-number command.

To view the receiving and transmitting power on all interfaces, run the display transceiver diagnosis interface command.
To view the receiving and transmitting power on an interface, run the display transceiver diagnosis interface interface-type interface-number command.
For example:

The display transceiver diagnosis interface GigabitEthernet 0/0/1 command displays the following information:

Port GigabitEthernet0/0/1 transceiver diagnostic information:
Parameter Current Low Alarm High Alarm
Type Value Threshold Threshold Status
------------- --------- --------- ---------- --------
TxPower(dBm) -4.83 -11.02 -2.00 normal
RxPower(dBm) NA -18.01 -1.00 NA
Current(mA) 6.38 2.00 14.00 normal
Temp.(C) 44.00 -20.00 90.00 normal
Voltage(V) 3.31 2.90 3.70 normal
