Hi,
I'm getting a little confused with max distances with qfx qsfp+.
QFX-QSFP+-40GbaseSR4 are given for distance of 100m over om3 mmf, 150m over om4 MMF.
I get it that we can configure the QSFP+ as a 40G unique channel or as 4 separate 10GbaseSR interfaces.
Simple question :
when split to 4x10GBaseSR separate interfaces,
-1/ does the max distances stated for QFX-QSFP+-40GbaseSR4 (100m@om3, 150m@om4) remain the max distances available on each 10GbaseSR interface ?
-2/ ... or does the max distance becomes the same as a native SFP+ 10GBaseSR interface (300m@om3, 400m@om4).
Not talking about the ESR4 qsfp+ here, just the basic SR4 qsfp+.
Juniper representative told me 1/ was correct.
Cisco told me 2/ was correct (on their boxes...).
So... who's right and who's wrong ...?
