Either you take 2 Cisco SFP-10G-LR modules with a fiber to connect them together (preferably Corning OS2 or Commscope TerraSpeed), or you take the Cisco AOC cable (orange) which is complete with the SFP+ connectors
It was this one…
Look at this one, it seems correct.
CISCO SFP-10G-LR 10G LR Gigabit 1310nm Transceiver Module - NEW & SEALED 882658782497 | eBay
Be careful not to take the version with S at the end, it is not compatible with all protocols (ethernet etc…), but I don’t remember what… Maybe SPaul who seems sharp on the subject knows it.
For Cisco, I cannot recommend a reliable supplier.
I received them from a good friend from the US who works in IT, but I can tell you that on the Cisco website there is a section where you can check, by serial number, the SFPs.
I can also tell you that in the application of my switch the Cisco SFP appears as a Finisar product, which is also the reason why many audiophiles use Finisar.
I recommend a seller, who is an audiophile enthusiast, who sells audiophile equipment for the network: Project Constellation FIBER - AfterDark
For Finisar, he is a reliable supplier:

Do you have holograms on your CISCO ?
Yes, at least read this thread: Finisar SFP+ Modules for Audio Grade Network Switch (Group Buy for Audiophilestyle.com) - Page 8 - AfterDark (Sponsored) - Audiophile Style

@SPaul, @PatriceP Thanks guys for the advice : Cisco SFP-10G-LR modules with a Corning fiber between RS130 and RSA720 is indeed a better combo than my previous ELFCAM SFP+ modules, and definitely in another league than the modules and single fiber provided by ROSE…
@SPaul You should try them again !
With pleasure!
Great care in purchasing SPF modules. There are many fake modules and so-called “compatible” modules on the market.
The difference is like from heaven to earth! I have shown above how an original Cisco module can be checked.
Regarding the “compatible” modules, it should be taken into account that they are produced by OEM companies and compatibility is obtained by writing the EPROM to be compatible with Cisco equipment.
The most important are the SFP modules, and the type of laser used in them.The most commonly used are, FP (Fabry Perot Laser), VCSEL (Vertical-Cavity Surface-Emitting Laser), DFB (Distributed Feedback Laser) also known as DML (Directly Modulated Lasers), and EML (Electro-absorption Modulated Lasers).

Yes, I will try again, maybe one of the modules did not work, or maybe the fiber was interrupted.

Hello,
Do you have a reference number for the optical cable and where did you order it from?
Which is better for RSA720-RS130: Cisco or Corning?
Thank you
