you can also get QSA adapters to convert from a QSFP form factor port to a SFP+ port. This should allow SFP+ WDM transceivers.However, the MX 10k family still only shows as being compatible with two QSFP cards. And yes, you can get a QSFP-SFP+ breakout cable, but those don't let you use SFP+ CWDM/DWDM transceivers.
