Verifying transceiver modules

You can verify the genuineness of a transceiver module in the following ways:

Display the key parameters of a transceiver module, including its transceiver type, connector type, central wavelength of the transmit laser, transfer distance and vendor name.
Display its electronic label. The electronic label is a profile of the transceiver module and contains the permanent configuration including the serial number, manufacturing date, and vendor name. The data is written to the storage component during debugging or testing.

To verify transceiver modules, execute the following command in any view:

Task	Command
Display key parameters of the transceiver in a specified interface	display transceiver interface [ interface-type interface-number ]
Display part of the electrical label information of transceiver in a specified interface	display transceiver manuinfo interface [ interface-type interface-number ]

# Display the main parameters of the transceiver plugged in interface GigabitEthernet 3/0/3.

<Sysname> display transceiver interface gigabitethernet 3/0/3

Table 20: Command output

Field	Description
Connector Type	Type of the connectors of the transceiver: SC—Fiber connector, developed by NTT LC—1.25 mm/RJ-45 optical connector developed by Lucent. RJ-45 CX 4
Wavelength(nm)	Fiber transceiver—Central wavelength (in nm) of the laser sent. If the transceiver supports multiple wavelengths, every two wavelength values are separated by a comma. Copper cable—Displayed as N/A.
Transfer distance(xx)	Transfer distance, where "xx" represents the distance unit: km (kilometers) for single-mode transceivers and m (meters) for other transceivers. If the transceiver supports multiple transfer medium, every two values of the transfer distance are separated by a comma. The transfer medium is included in the bracket following the transfer distance value. The following are the transfer media: 9 um—9/125 µm single-mode optical fiber 50 um—50/125 µm multi-mode optical fiber 62.5 um—62.5/125 µm multi-mode optical fiber TP—Twisted pair CX4—CX4 cable
Digital Diagnostic Monitoring	Support for the digital diagnosis function: YES—Supported NO—Not supported
Ordering Name	Product code.
