How can I find what optic is in an interface for a Juniper MX-series router?

Question

As the title states, how can I see what optic I have installed in an interface for an MX router?

You need to be looking under the show chassis hardware stanza. That gives you all the inner-workings of the devices plugged into the chassis, including VC members.

On an MX platform, this is along the lines of what you'd expect:

user@host> show chassis hardware

^{Sample information derived from Juniper TechLibrary}

Or perhaps you don't buy everything from Juniper and/or you live in a multi vendor environment (like me). Your system will look eerily similar to this:

FPC 0            REV 20   750-045402   LX0XXXXXXXXX      EX4550-32F
  CPU                     BUILTIN      BUILTIN           FPC CPU
  PIC 0                   BUILTIN      BUILTIN           32x 1G/10G SFP/SFP+
    Xcvr 0       REV 01   740-021309   ARS0HB7           SFP+-10G-LR
    Xcvr 1       REV 01   740-021309   ARS0HB2           SFP+-10G-LR
    Xcvr 12      c        NON-JNPR     FNS0838H4CB       SFP-LX10
    Xcvr 13               NON-JNPR     FNS0838H4AJ       SFP-LX10
    Xcvr 14      M        NON-JNPR     FNS0835T08U       SFP-LX10
    Xcvr 15               NON-JNPR     FNS0838H4B0       SFP-LX10
    Xcvr 16      U        NON-JNPR     FNS0835T0C2       SFP-LX10

Although this is on an EX4550, the transceivers marked NON-JNPR would show up the same on an MX platform. It's not a malfunction, the system just doesn't recognize the device signatures. If you want additional information on them, such as the vendor, fiber wavelength, or fiber type, use the show chassis pic fpc-slot <FPC> pic-slot <PIC>.

rj@MHN00525CN01> show chassis pic fpc-slot 0 pic-slot 0
FPC slot 0, PIC slot 0 information:

  Uptime                         56 days, 6 hours, 5 minutes, 6 seconds

  16   GIGE 1000LX10     SM    CISCO-FINISAR      FTRJ-1319-7D-CSC  1310 nm  0.0

Most of the time, though, show chassis hardware will be more than sufficient.

Have a look at the output of

show chassis hardware

and

show chassis pic fpc-slot <X> pic-slot <Y>

In general:

show chassis hardware

In particular, if you don't get enough information there you can try:

show chassis fpc pic-status

show chassis pic pic-slot PIC_ID fpc-slot FPC_ID (substitute with the proper IDs of course)

Although this is a nice diagram, it doesn't seem to answer the question. The OP is asking to discover which type of optics are actually installed , not what the port numbers are. – Ron Maupin Mar 20 '16 at 17:46
