How to view the type of an optical module

0

If the optical module has been inserted into an interface, you can run the display transceiver interface command to view the type of the optical module.

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

How to view the serial number of an S series switch
Serial numbers of S series switches fall into two categories: - Equipment serial number (ESN): indicates the serial number of a switch. The ESN of a modular switch is also called the chassis serial number. - Serial number (SN) of each component: indicates the serial number of a card, subcard, optical module, power supply, or fan module. Select one of the following methods to obtain the ESN or SN of a switch or component: Method 1: View SN labels. Equipment or chassis SN: View the SN label attached to the device panel. (There is a slight difference between label locations on different models. For example, the label can locate on the front, rear, or top of the chassis.) Card serial number: View the SN label on the panel (upper-right or upper-left corner) or PCB (remove and check the card). Method 2: Run a command. Run the display elabel command to view the electronic label of each component. The BarCode field indicates the serial number. Method 3: Through the web system. When the web system is enabled on a device, view the chassis serial number through the web system. EasyOperation web system (supported only in V200R005 and later versions) Log in to a device through the web system and click Monitor on the toolbar to enter the Monitor page. You can view device information, including the chassis serial number. Web system classical version Log in to a device through the web system and click Device Summary on the toolbar to view device information, including the chassis serial number.

Specifications and types of DCM optical modules
DCM optical modules are classified into multiple types, which correspond to compensation distances of 5 km, 10 km, 20 km, 40 km, 60 km, 80 km, 100 km, 120 km, 160 km, 200 km, and 240 km.

Which type of optical module is used by the MCU optical port: single-mode or multi-mode optical module? How can I choose the optical module?
The MCU board supports only the SFP optical module. Set the IP address to the IP address of GE0 port. Whether an optical module is a single-mode or multi-mode optical module is determined by its optical module attribute settings. To use an optical module, set the attribute to optical port module. When an optical module connects to an optical port, the system automatically switches to the optical port module mode. By default, the multi-mode optical module is delivered with the product. The customer can choose a single-mode optical module if required during the order process. The optical module, like network cables, is not the default configuration; therefore, you need to purchase one. If you select the optical module, the multi-mode optical module will be delivered and charged by default.
