    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 remotes.


    The price difference is made reducing downtime in our case.

For someone who doesn't want to deal with outages, call-volume, hands

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 longer term after 18 months give or take a little bit. The 
failed units typically come from interfaces that run at very high utilization 
levels 24x7 but have never done any more correlation than that.

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 switchport... oops.

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 management.

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 I've put them in.

And if you buy them coded to said switch/router vendor (or code them yourself 
with the "fs box" which is reasonably priced), said switch/routers usually 
start cooperating for you.

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, but this is just 
an attempt to keep customers captive to insanely overpriced OEM parts.

FS.com’s bi-di modules are particularly ingenious, letting you add 
bidirectional fiber to devices the oem manufacture doesn’t even sell optics for 
in an attempt to create artificial product segmentation.

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.

Anyone have experience with fs.com's lasers? Are they reliable?

RE: sfps from fs dot com

[Kevin McCormick]

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,

Kevin McCormick

Indeed.  My tune would be very different if we had 1:50 fail in the field.

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 they seem to always be within 
spec.


They're cheap enough to keep several spares around and still come out 
ahead of buying name-brand let alone OEM vendor-branded optics, too.
