Hello All,

Does anybody have experience with fs.com dwdm equipment in their production environment? Are you they working without any issue? How’s their warranty support if the issue arises?

Thanks in advance for all the answers and help.

I tryed SFP, MUX, DEMUX and OADM, all working as expected.

They have solid product and good support, I bought many SFP+ for Nexus, Juniper, Force10 and never had a problem with them.

We’ve purchased many SFP modules from fs.com for Cisco gear, and the only problem we run into is that Cisco IOS seem unwilling to expose the error counters via SNMP. This is kind of annoying, because that’s how we get early warning of fiber problems. I suspect IOS does this deliberately because it notices the module is not OEM. But the cost savings with fs.com is tremendous, so we put up with this inconvenience.

On a side note, their sales support is always prompt and very personable. Technical support seems to be limited to offering free advance warranty replacement shipping. With a few hundred modules, we’ve had maybe two dead ones. So less than 1% iinfant mortality on pretty complex optics.

For managing them, do you use the actual software they ship with it? When I last checked, it requires a MSSQL instance with hard coded “sa” user access which was an immediate no go for me. I still have them sitting in a box in our lab as a teaching aid really.

We use it. A lot of it. No problems. Never a need for warranty support.

Samir,

I have purchased over a thousand SFPs from Fiber Store. I can recall less than 5 having problems when we received them (not all even DOA) and I know less than 10 dead even after deployment. Some we have ad running for 4+ years. We have done very little with their SFP+ equipment, really only testing and a few lower priority links.
The only downside to the SFPs that we found was the variance of power. Say an Adtran, Cisco, Juniper, HP SFP is rated from -3dB to -8 db (all units I have used them with), the equivalent FS direct SFP we have seen as hot as 3dB and as weak as -15dB. These extremes are fairly rare but we have still seen them.
Distribution (approximate):
80% SM single fiber SFPs (mostly 10km - 40km, some 60km & 80km)

7% 1Gb Copper

5% MM SFPs
5% SM dual fiber SFPs
3% others (SFP+, GPON, testing, etc)

I have not used them for any DWDM applications and only used them a few times on an older CWDM link that used standard SFPs into a MUX. This was not over great distances (less than 40 miles). With WDM SFP power consistency was important so we did not play much with it, granted most of the SFPs I am purchasing are in the $10-$25 range so take the extremes with a grain of salt.

Their sales has always been very responsive and helpful. The support/engineering, the few times I worked with them, were helpful but the language barrier was harder here.

I concur. I have also used CWDM and DWDM optics and they are fine. I have had one QSFP+ optic go bad.

Hi,

I have both 1Gig and 10Gig DWDM optics from SF.com being using in Cisco and Mikrotik switches.

Never had an issue with them. Work flawless .. for years.

Kind regards,
