Hi,
Back last year, I experienced less than expected reliability with
QFX and their QSFPs.
We prefer to use optic.ca since they're a few minutes from our DC's
and will respond within the day, with platform and firmware changes,
which we can test in lab before shipping to our
Another vote for Approved here, awesome group of people and very thorough in
their testing and fault analysis. We buy from them for Juniper, Ciena,
Mellanox, Intel and a bunch of other random stuff.
I’ve had mixed results with FS. Some stuff works fine, others we have high
failure rates on
I've got a whole bunch running with no issues.. Mostly MM/850nm though, so
maybe a bit different than their SM stuff. Also have a handful (literally)
of the SM ones, and haven't had any issues (yet).
Only "problem" I've had is a copper SFP from them which may have burned out
and fried a

I have a few hundreds of them, started buying from them about 3 years ago, not
a single issue so far.
I'm going to buy their box soon, so I could recode a Cisco optic into an HP
one, easier on spares
We have had some failures with 10G BiDi optics coded for Juniper. We buy a
ton of other stuff from FS but for optics we have moved over to Approved
Optics for everything but active ethernet residential subscribers.

I have had some fail and SFP+ & QSFP28s that my Juniper MC480s refuse to
recognize even though I ordered 'branded Juniper' optics.
99% of my stuff is from FlexOptix (https://www.flexoptix.net/). They are a bit
more expensive but I've had 100% reliability and they have worked in all
systems

We buy them extensively and have had zero data problems with more than 300
parts in the field. Some switch/router manufacturers’ firmware poutily refuses
to let you read snmp stats from any “unauthorized” SFPs modules, and some oem
salespeople lyingly claim that using them voids your warranty,
Had some issues in the past with Juniper-coded LR4 with sporadic
disconnections. Apart from those I don’t have any complaints beyond the odd
DOA.

Biggest issue I've seen is it may work on some Cisco models and not others. I
got their flashing box to just reflash the firmware and that has fixed even
"dead" optics.

Yes. I never have seen a failure in the last few years.
We have used Cisco compatible 1G / 10G DAC, SR, LR, and DWDM.
Buy spares if you are concerned, they are priced so you can.
We do like having spares in a rack drawer.
Thank you,

It boils down to a business case.
In my travels we see a high failure rate -- higher than I'd like to see
--, but $boss likes the price, and, as Jason pointed out below, for the
price, it can be a "successful" business model.
In a nutshell:
For someone on a budget, they're great; buy
We have maybe 1:50 DOA, but they’re so cheap, we just throw them out because
it’s not worth the RMA.
That said, I can’t remember the last time we’ve had any of these fail in the
field, or have had any issues with variablity in TX/RX power. We have tens of
thousands of these in the field, from

YMMV.

I've had no complaints about reliability. In terms of transmit power
and receiver performance, they seem to have a bit more variability than
some of the bigger brands' offerings, but
