Hello, all!

There is new switch X870 with QSFP28 ports.
Would it be normal working QSFP+ in this ports?

As I saw - wavelenght and formfactor the same.
Also Juniper have normal compatibility in such case.

Thank you!

the 870 ports can be 100, 50, 25, 40, 10 gig.  if they are configured for 40 or 4*10 then the regular qsfp+ cabling will work.  so the part numbers for qsfp+ are correct as well for 40gig qsfp+ optics and twinax cables.
