    type is 10Gbase-(unknown)  <<<< Why is this nt getting recognized.

    name is CISCO-AVAGO    

    part number is SFBR-5766PZ-CS1

    revision is    

    serial number is  AGXXXXXXXXX

    nominal bitrate is 1300 MBit/sec

    Link length supported for 50/125 um fiber is 550 m

    Link length supported for 62.5/125 um fiber is 270 m

    cisco id is --

I think I have an idea what's going on ...

PID "SFBR-5766PZ-CS1" is a 1000BaseFX SFP and you are running NX-OS 4.X.

Is this SFP module installed in a M148 line card?  If not, then you need to upgrade the NX-OS to the appropriate level as stated in the Release Notes (Table 4).

Based from the following output:

You put a 1GE SFP into the M132 line card and M132 only support 10GE SFP. The conclusion is your are using the wrong SFP.
