Re: [j-nsp] ACX5048 - 40 gbps ER 40 km optic

We have some QFX´s here with 40gigs  and 100gigs optics from Precision
optics too for about a year in production without a single hitch..

[Alain Hebert]

    Well,

    We had a few issues with FS.com devices in our QFX's.

    We're still looking if its the platform or FS.com.

    Although we replaced them with Juniper certified devices from 
optic.ca and its going better for the past 3 weeks.

As Sebastien mentioned above, this output means that you don't receive any
light. -40 dBm is just a fancy way to say "darkness". At the same time you
see some emitted power, this means you "send" light to the other end.
Check it on both sides: if A doesn't see what B emits or vise-versa, it
normally means you have a problem in the middle. Check your cabling (make
sure that it's not MMF :) NB: as 40GE is technically 4×10GE (wavelength
multiplexed in this case), you have four lanes for each port, this is why
it's called Quad-SFP and ER4.

When you manage to have the light on the other side of your fiber, you
might face another problem. As this is an ER, you can saturate your
receiver if you don't have enough attenuation. So either use an attenuator
or the above mentioned common trick with turning the fiber around your
finger to let the light escape through the cladding (fix it with tape). See
Chuck's comment for more details.

Or just replace the optics with a QSFP-DAC )

Insert a 3dB or 7dB attenuator pad for lab testing.  In a pinch (no pun 
intended) you can take a fiber jumper and bend it tightly into a loop (like 
1/4" diameter) to attenuate the signal, but I would use a disposable jumper for 
that.  Use a twist tie or similar to hold it in the tight loop.  Monitor the 
receive power level while adjusting the tightness of the loop until it is lower 
than -5 dBm but higher than -20 dBm.

Re: [j-nsp] ACX5048 - 40 gbps ER 40 km optic

[Alexandre Guimaraes]

Aaron,

   I use them, yes, not in the lab, in the real world, the distance is 37km.

   40Km transceiver use high power, much more than 10km transceivers, you have 
to attenuate to decrease power and fit the threshold.
Use “show interface diagnostic optics et-0/0/x” to check the levels.

The acx or any other Juniper switch will disable the interface if the 
signal does not match the threshold.

Hi Aaron,

 

Juniper does not list that modul as supported for your platform:

 

https://pathfinder.juniper.net/hct/product/#prd=ACX5000

 

Maybe the power budget per port is not high enough for the 40km laser.

 

And you should not connect them directly because you may blow up the receiver - 
launch power is higher than the receiver might can handle:

 

Average launch power per lane

–2.7 through 4.5 dBm

Average receive power per lane
–21.2 through -4.5 dBm

Re: [j-nsp] ACX5048 - 40 gbps ER 40 km optic

[Pavel Lunin]

The command you are looking for is called "show interfaces diagnostics
optics".

Re: [j-nsp] ACX5048 - 40 gbps ER 40 km optic

[Sebastian Becker]

Hi Aaron,

Juniper does not list that modul as supported for your platform:

https://pathfinder.juniper.net/hct/product/#prd=ACX5000 


Maybe the power budget per port is not high enough for the 40km laser.

And you should not connect them directly because you may blow up the receiver - 
launch power is higher than the receiver might can handle:

Average launch power per lane
–2.7 through 4.5 dBm

Average receive power per lane
–21.2 through -4.5 dBm

[j-nsp] ACX5048 - 40 gbps ER 40 km optic

[Aaron Gould]

I put this into my ACX5048 in the lab today. actually 2 of them.
QSFP+-40G-ER4 (aka QSFPP-40GBASE-ER4) SMF 40 km 1310 nm optic

 

Optic is seen in cli, but I see no led's on chassis and when I plug them
into each other, interfaces stay up/down.

 

Is there something I need to do to make this 40 gig optic work in the
ACX5048 (JUNOS 15.1X54-D61.6) ?
