Juniper SFP's

Hey all,

<rant>

Juniper are really pissing me off in regards to their SFP's.

As an example:

CTP-SFP-1GE-SX (0)
EX-SFP-1GE-SX (163)
JX-SFP-1GE-SX (2)
QFX-SFP-1GE-SX (5)
SRX-SFP-1GE-SX (4)

Is there ANY actual difference between these SFP's? They are all the same
price from the distributor but they all have different availability - see
number above for example from one of my disties.

I recently deployed some MX80, EX4200 and SRX240 and had to order different
SFP's for them all.. and the SRX one took ages...

There is likely to be no difference, but will JTAC tell me to get lost if I
use an EX one in an SRX or MX or vice versa?

*Frustrated*

Does anyone have experience with the compatibility of the generics?
Agilestair or so on? I really am happy to sell genuine Juniper SFP's, but
why the hell are there different codes for each one? Why am I waiting for
stock for 3 weeks for an SRX one when they have 163 EX ones.

</rant>

Have a nice day ;-)

Re: Juniper SFP's [In reply to]

Skeeve,

I can't speak to the differences in the Juniper SFP types, but I can tell you I've seen generics of all kinds work in EXs, MXs, Ms, and SRXs.

I've never had one go bad and I've never had JTAC mention the generic-ness of them when opening tickets. YMMV, however.

Agreed.

Yes. The QFX3500 actually requires QFX-specific SFP/SFP+ and even the
Juniper OEM ones for other Juniper products will not function in a
QFX3500, at least as of 11.3. A little bird told me that they will
remove the optics lock-in sometime this year. The sooner this
happens, the better.

I, too, am not willing to wait for Juniper to supply me with SFPs,
especially since Juniper is honestly pretty bad at supply chain /
logistics, and does not even offer colored SFPs for some of these
products. Cost is not the overriding concern here, it is
AVAILABILITY.

We literally shipped a QFX3500 to a third-party optics vendor's lab
and had them figure out how to re-flash generic optics so they would
work in it. This because our SE gave us an incorrect answer about
whether or not it would work with generics -- turns out it doesn't.
One of my clients was so angry about this that they returned some of
their QFX3500s and got their money back over this, and bought another
manufacturer's product instead.

I can only guess that the reason Juniper has different SKUs for the
optics for different product families is that this is the mechanism
they use to credit the optics revenue to the correct product group,
and this must be why the QFX won't work with Juniper optics from other
product lines.

We've been using generic SFPs and XFPs in Juniper M and MX routers
for many years. Never had a problem except, as others also have noted,
not all 1000baseT SFPs work equally well.

At one point I was using LX optics from one platform in another (I think it
was MX in SRX, but that could be backwards). They worked fine, but DOM was
showing really odd values (33 volts, module temperature of several hundred
degrees, etc.). The counters looked normal once I switched them out for
the "right" optics.

They were third party optics but they were programmed for those platforms.
I don't have any Juniper optics in that variety so I don't know whether
they'd behave the same.

I've had good luck with Approved Optics. I try to stick with Juniper on
devices that have a lot of optics (since it would be a pain to change them
all out if JTAC tried to blame the optics for a problem), but I might
change that strategy if I had enough devices to warrant sparing Juniper
optics (for JTAC-compatible changeouts) in appropriate quantities.

One of my clients has informed me that 11.4R2 appears to fix the "link up" issue for some generic Copper SFPs. Spectacularly undocumented of course, but if you don't mind living on the bleeding edge, give it a go.

Re: Juniper SFP's [In reply to]

Hi Jeff , we used an ex optic in a qfx and it was ok - also noticed the
part number is the same..... Didnt realise there was any lock ??

Re: Juniper SFP's [In reply to]

+1 :)
I'm willing to give them the benefit of the doubt, but are they different
enough to warrant all the different part numbers? How about a universal
SFP that works across similar products. I can't comment on the others but
I've seen the EX and MX/M SFP's interchanged. More often than not it
happens by accident. Juniper adds to the fun by not printing the part
number on most of them.

Re: Juniper SFP's [In reply to]

my SE in our local US office told me that juniper do this to "claw back R&D
costs". Now that may be hearsay but it certainly makes sense on how they
position their different SFP's and prices. I was a Juniper advocate back in
the late 90's up until mid naughties, but now they are losing the plot. It
was inevitable they would go down the cisco route in attitude and pricing.
Shame really.
