[j-nsp] 3rd party DWDM SFPs

You can get a *little* more info from "show chassis pic":

FPC slot 2, PIC slot 1 information:
  Type                             4x G/E SFP, 1000 BASE
  ASIC type                        SFP GE FPGA
  State                            Online
  PIC version                  1.5
  Uptime                        175 days, 7 hours, 57 seconds

PIC port information:
                          Fiber                    Xcvr vendor
  Port  Cable type        type  Xcvr vendor        part number     Wavelength
  0     GIGE 1000LH       SM    FIBERXON INC.      6128C-SL5051G   1510 nm
  1     GIGE 1000LX       SM    CISCO-FINISAR      1000BASE-LX     n/a
  2     GIGE 1000LX       SM    CISCO-FINISAR      1000BASE-LX     n/a
  3     unknown cable     SM    CISCO-FINISAR      F-WDM-1530      n/a

So here we have a 1510nm SFP in 2/1/0 and a 1530nm SFP in 2/1/3. However,
it's not the complete EEPROM contents by any means...
