| Q: |
What are some of the common failures found that inhibit GBIC/SFP transceivers from working properly? |
| A: |
When a GBIC/SFP transceiver fails to work properly, please check for one of the following:
a)Whether the GBIC transceiver is properly inserted.
b)Whether the transceiver gives out alarms normally.
c)Whether the output optical power of the GBIC transceiver module is normal.
d)Whether GBIC transceiver is shut down by the ¡®¡±TX Disable¡± signal.
e)Whether the receiving optical power of the GBIC transceiver module is within the operation range.
f)Whether the power supply is right (in the range of 3.13V-5.5V) and the host board is working normally.
g)Whether the information in the EEPROM of the module is accordant with the GBIC MSA specification (SFF-8053).
h)Whether the proper fiber is used.
i)Whether the GBIC transceiver modules are working in pairs; whether the situation of having a 850nm transceiver on one host and a 1310nm or 1550nm GBIC transceiver on the other host is happening.
j)Whether the fiber¡¯s end-face is obscured by any contamination. If yes, please clean with proper cleaning procedures.
k)Whether the transceiver¡¯s receptacle or fiber¡¯s connector is damaged. If yes, please replace it with a new one. |
