FAQ-How to Check the Output Power and Input Power on the ME60

Publication Date:  2012-07-27 Views:  55 Downloads:  0
Issue Description
 Q:
How to check the output power and input power on the ME60? 


 
Alarm Information
 Null 

 
Handling Process
 A:
Do as follows:
[ME60]_h
//Enter the hidden view.
[ME60-hidecmd]sfp-debug 10 0 0
//The parameters following sfp-debug indicate the slot ID, subcard number, and port number.
XFP module temperature: 29.43 (C)
//Temperature of the module
XFP Tx bias current: 57.19 (mA)
//Current of the module
XFP Tx output power: 1.47 (dBm)
//Output power
XFP Rx input power: -2.73 (dBm)
//Input power
XFP Laser Temperature: 33.54 (C)
//Temperature of the module laser
XFP 5.0V supply: 4.95 (V)
//Voltage of the module
Note:
1. The version is irrelevant to the optical power.
2. The command is irrelevant to the type of the POS optical module.
3. The command cannot be used to check the information about FE and GE modules. 

 
Root Cause
 Null 

 
Suggestions
 The optical power can be checked only when the interface uses the POS optical module or eSFP optical module. If the interface is a POS interface, you can run the sfp-debug command in the hidden view to view corresponding information. The difference between SFP and eSFP needs to be clarified.
SFP is short for Small Form-factor Pluggable; eSFP is short for enhanced Small Form=factor Pluggable. An SFP module and an eSFP module are the same in terms of main functions and services. As long as the optical power, sensitivity, and distance are the same, they can be exchanged with each other. Their difference is that eSFP has some additional functions. For example, an eSFP optical module supports the monitoring of optical power, whereas a traditional SFP optical module does not support such monitoring.
