How to view optical power parameters

0

Run the display transceiver interface command to view optical power parameters.

For example:

Function of the rated optical power parameter for OBU1 and OAU1
When optical cross-connections are used, this parameter serves as the reference for automatic optical power adjustment of OPA. When optical amplifier units and ROADM units are used in a network, you need to set this parameter for the optical amplifier units. You need to configure the values of the rated input and output optical power of the optical amplifier units to be the same as the values measured when the optical amplifier units operate normally. When the function of automatic optical power adjustment is enabled, this parameter affects the optical power budget of the optical path of the system.

How to view the type of an optical module
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. display transceiver xgigabitethernet 2/0/0 XGigabitEthernet2/0/0 transceiver information: ------------------------------------------------------------- Common information: Transceiver Type :XFP-STM64-LX-SM1310 Connector Type :LC Wavelength(nm) :1310 Transfer Distance(m) :100000(9um) Digital Diagnostic Monitoring :YES Vendor Name :HUAWEI Vendor Part Number :02315208 Ordering Name : ------------------------------------------------------------- Manufacture information: Manu.

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.
