Show transceiver specs on Cisco ASR 9000

The equivalent of a “show inventory” or a “show interfaces transceiver” on a Cisco ASR 9000 is “show controller”:

# show controller tenGigE 0/0/0/0
[...]
Phy:
    Media type: R fiber over 1310nm optics
    Optics:
        Vendor: FxxxxxR
        Part number: FTLXxxxxxxxxL
        Serial number: AxxxxxU
# show controller tenGigE 0/0/0/0 internal
[...]
Pluggable Type      : SFP-10G-LR
# show controller tenGigE 0/0/0/1 internal
[...]
Pluggable Type      : DWDM-SFP-5494

It shows you the phy details of a specific interface transceiver, while “internal” shows you its type (LR, SR, DWDM, …)
