[c-nsp] SFPs (Third party) - ordered "standard" LH, but got "ZX"

[Mack McBride]

If they are 1310nm then they definitely are not ZX which are 1550nm.
EX are also 1310nm which are generally 40km.
I am guessing it is just a bug in the ASR.
As others have said, cisco doesn't always work right even with their own
Optics.  If you didn't have to resort to transceiver permit pid all or transceiver unsupported
When placing them in equipment then consider it a win.

The light levels are consistent with LX/LH.
EX transmit levels are above -1 db
And ZX transmit levels are above 0 db.

Oh one more thing:  I’ve noticed that some 10KM SFPs come as 20km capable:

Date Code: 150213
1000Base-LX
extended compliance_code 0
Distances:
        SMF - 20 km
        SMF - 20000 meters
        OM4 - 320 meters
Wavelength: 1310.00nm

It’s possible that the router interprets >10km as ZX.
