FlexOptix will give you the programmer for the SFP’s if you buy a
minimum lot of SFP's. They have profiles for all of the major
manufacturers that will tell the equipment it’s a branded SFP. For
the items they don’t have a profile for you just need one of the
manufacturers coded ones to suck the configuration out and blow it
back into a FlexOptix SFP. Works great. You can even have them
modify a profile for a SFP if you need to lie to the equipment about
what it is you installed - like a BIDI single mode pretending to be a
standard multimode.
German company but they ship Fedex overnight at reasonable cost.

That is the case with many if not most vendors that use SFPs.
Even back in the SONET days, Alcatel would not gracefully talk to
Fujitsu. They would talk but there were all kinds of alarms on both
ends.

And the random SFP I tried a few years ago actually worked perfectly
fine by the way. The only difference was the Compact would toss alarms
about it on a regularly schedule. So apparently you can use any SFP as
long as you're willing to ignore the alarms.

Hi Adam
Telrad show two transceivers for Compacts on their Zendesk site.
I think this one is Single mode.

I have asked FS.com if they have a compatible module.

Save yourself the hassle and never use multimode for anything.
Multimode is always a mistake at some point in its lifetime.
Singlemode is forever.
Single mode is better in all cases.
The only reason for multimode was that the the transmitter for
single mode is a laser and lasers were expensive. Multimode uses
LED transmitters which were cheaper. VCSEL Lasers turned that
upside down and single mode is the cheaper one now. The fiber
itself costs about the same.
There are always exceptions. Last I knew the only "approved" SFP
for a Telrad Compact was a multimode one. The device will toss
alarms if you put in any other SFP module.
....and I'll grant you that I last tried a 3rd party SFP about 2
years ago, so this could have changed, but it was definitely true
in 2015 & 2016. So all of our Compacts have a multimode fiber
cable. Cest La Vie.
It was also the case that SFPs with industrial temperature spec
were cheaper in multimode. I'm not sure if that's still true, but
it was for awhile.
