QSFPP-4X10GE-LR @ 40Gb?

‎07-02-2018 05:33 PM

Can a QSFPP-4X10GE-LR optic operate as a single 40Gb interface? Or does it work only as 4x10Gb channelized?

Hi Folks,

Based on my understanding QSFPP-4X10GE-LR QSFP+ 4x10GbE can be used as only 10GbE interface and not as a single 40GbE interface. You will need a 4X10G BREAKOUT cable to connect to the other end.

 

The below has few pointers on 10G-40G QSFPP Second Generation PTX Series PICs,

I actually believe the answer is yes, that it can support 40GE (via 4 x 10GE wavelengths) or be used with break-out cable. If you go to Pathfinder here - https://apps.juniper.net/hct/model/?component=QSFPP-4X10GE-LR&tab=sPlatforms and hover over the red "i" circles, the info appears to say that this transceiver can be used in either configuration.

 

The first question I might ask is, for which Platform are you planning to use this specific transceiver?

This optics supports both the 40GE in 4 parallel single mode fiber (PSM4) link configuration and 10GBASE-LR IEEE Standard in 4xbreakout application.

To use this Optic in 4 x 10GE, one would need to go in and configure channelization of the interface.  Otherwise functions as 40GE (via 4 x 10GE parallel wavelengths).

 

YES?

Sorry for the late response Smiley Happy

 

This would be for a QFX10002-72Q. If I channelize this optic and use an MTP->LC breakout, will each channel run at 1310 so that I can use standard LR's on the other end?

Yes.  See here for specs - https://apps.juniper.net/hct/model/?component=QSFPP-4X10GE-LR

 

From there it states:

 

Transmitter wavelengths (range).          1260 nm through 1355 nm (this is 1310)

 

All this info can be found on-line.

 

HTH.  Regards.

Update: Unfortunately this optic (for some unknown reason to me!) is NOT certified for use on any QFX capable platform.  See here - https://apps.juniper.net/hct/model/?component=QSFPP-4X10GE-LR&tab=sPlatforms

 

At the same time, since all optics are standards based, the optic should/will work fine, and you can considered as you would as a 3rd party optics.  At least at the present time.

 

I will check further, and update if I find any additional info.

Oh, interesting. But I do see it here under a different name:

OK.  I suspect they each call out same Optic, but I'll check into it.  Thanks for the info.  Best for any QFX usage that you order JNP SKU if possible.
