ISR 4331 show transceiver wavelength

[matthew-d-rogers]

Is there a command for the ISR 4331 running 16.12.03 (Gibralter) to show an installed transceiver's wavelength?

I have an ISR 4331 with an SM-X-16G4M2X module installed. I am using DWDM optics in the 10G ports. I can get just about all the information for these interfaces except the wavelength:

Router# show hw-module subslot 1/0 transceiver 20 idprom
IDPROM for transceiver TenGigabitEthernet1/0/20:
  Description                               = SFP or SFP+ optics (type 3)
  Transceiver Type:                         = SFP+ 10GBASE-ER (276)
  Product Identifier (PID)                  = XCVR-S80W34-IO
  Vendor Revision                           = 01
  Serial Number (SN)                        = V29W9W80
  Vendor Name                               = INTEGRAOPTICS
  Vendor OUI (IEEE company ID)              = C8.DE.51 (13164113)
  CLEI code                                 = 
  Cisco part number                         = 
  Device State                              = Enabled.
  Date code (yy/mm/dd)                      = 19/07/10
  Connector type                            = LC.
  Encoding                                  = 64B/66B (6)
  Nominal bitrate                           =  (10500 Mbits/s)
  Minimum bit rate as % of nominal bit rate = not specified
  Maximum bit rate as % of nominal bit rate = not specified

Router# show hw-module subslot 1/0 transceiver 20 status
The Transceiver in slot 1 subslot 0 port 20 is enabled.
  Module temperature                        = +29.906 C
  Transceiver Tx supply voltage             = 3309.1 mVolts
  Transceiver Tx bias current               = 40476 uAmps
  Transceiver Tx power                      =  0.7 dBm
  Transceiver Rx optical power              = -18.4 dBm

Running "show interfaces" does not display the wavelength either, I'm afraid. Any help would be most appreciated. Thanks.

To answer my own question (and for anybody else who has the same question):

show hw-module subslot 1/0 transceiver 20 idprom detail

That produces a lot of useful output, but the zero in on the wavelength:

show hw-module subslot 1/0 transceiver 20 idprom detail | include wavelength

Router#show hw-module subslot 1/0 transceiver 20 idprom detail | i wavelength
  Nominal laser wavelength                  = 1550 nm.
  DWDM wavelength fraction                  = 1550.92 nm.
