SPF+ and XFP Compatiblity

[rasmus]

Are SFP+ and XFP are compatible (i.e. can be used at the end of point-to-point fiber link) if they are with same specification, e.g. SM, 10Gbps, 10km

Note: actually i want to terminate a 10Gbps link on Juniper EX-3200 (with EX-UM-2x4SFP) and SRX3600 (with XFP module)

That is a typical deployment. That will work fine.

I currently have a EX4500 SFP+ connected to a NS5400 XFP, all is working well.

Should there be a standardisation for XFP and SFP+?

What would be the finer differences between SFP+ and XFP?

There is... both XFP and SFP+ are standardized form factors.

The difference is physical.  XFP is larger than SFP+.  An XFP optic cannot be used in an SFP+ port, and vice-versa.

Simply put -- the two are not interchangeable, but they are compatible.  Meaning they can be used at opposite ends of a physical link, as long as they conform to the same wavelength and signaling rate.

For example, a 10Gbps Ethernet Single Mode LR XFP on one end will work fine with a 10Gbps Ethernet Single Mode LR SFP+ on the other end.
