Which SFP modules should I choose to connect HP and D-Link?

Question

Computer networks

Good afternoon!

Please tell me which SFP modules to rip out to connect 2 switches
1. HP 1910-8G-PoE JG350A (SFP modules J4858C, J4859C, J8177C, JD089B, JD118B, JD119B, JD493A, JD494A)
and
2. DGS-1210-10 ( Module List DEM-302S-BXD, DEM-302S-BXU, DEM-302S-LX, DEM-310GT, DEM-311GT, DEM-312GT2, DEM-314GT, DEM-315GT, DEM-330R, DEM-330T, DEM- 331R, DEM-331T, DGS-712)

I noticed that HP has all modules with 2 ports, and I have one fiber. Singlemode.
Previously, there was already a similar question, DEM-330 seemed to work. (And they are with one port)
And using HP on the one hand and D-Link on the other does not seem to work, maybe they have different wavelengths?

I will be glad to any advice, tk. I am facing this issue for the first time.

Thank you!

Answer 1

If you only have one fiber, you are limited to WDM modules only. For single mode fiber as you report.
WDM modules transmit at one wavelength and receive at another. Accordingly, a pair of modules is needed, in which the wavelengths coincide "crosswise" - one module broadcasts on a certain wave, the second listens. And vice versa. If at the same time they also have the same speed, then there will be peace, traffic and happiness between them ... and, as a rule, do not care about the vendor, I worked (and in some places still work) complementary pairs of the wildest combinations.
No, it's still half the battle. The SFP module is a fairly intelligent machine. And in order for it to work correctly and successfully in the switch, it must be acc. stitched in a way. And here I have bad news for you - if D-Links are quite "omnivorous", and SPFs get along with them, as a rule, "sparkling", then HP equipment is rather capricious in this sense. And you need to check a specific switch and a specific SFP - whether one will start in the other, or not. But here, either experimentally or upon purchase, clearly indicate that SFP will work at HP.

See modules with the DWM option, and select according to their characteristics. Well, or buy modules from alternative manufacturers. Yes, and it all depends on the single-mode or mogo-mode fiber, the first is preferable.
