does these items will work together?
Mikrotik CRS317-1G-16S+RM
SFP+ direct attach cable, 3m (S+DA0003)
HPE Ethernet 10Gb 2-port 530SFP+ Adapter ( 652503-B21 )
I run successfully (out-of-the-box)
HP Mellanox 10GbE Connext-2 1Port 10GbE 671798-001
Cisco 3M SFP+ direct attach cable
Mikrotik CRS326-24G-2S+RM
Of course not a guarantee that your setup works …
Why bother with DAC? Transceivers are not much these days.
I use Intel X520 SR1 (comes with Intel transceiver)connected to CRS317-1G-16S (MW-SX+MM-US transceiver) using an actual fiber patch cable as it was intended.

Whilst I understand that product recommendations are off topic can anyone help by explaining what the critical factors are when looking for SFPs that are going to be compatible with a new service?
Is wavelength a defining factor that should be considered/matched or should anything else be used to guide selection?
Sorry I am new to 10G BASE-SR and I can’t seem to find a good resource that can confirm if an SFP supported in a Cisco Nexus 5548UP will be compatible with a new service The new service is described as ‘10 Gigabit Ethernet LAN PHY IEEE 10G BASE-LR10.3125 Gbps +/- 100 ppm 1310nm’
Ultimately I need to understand if a ‘cisco sfp-10g-sr’ for which the transmitter wavelength spec is described as 850nm is usable.
Thanks for your patient, i plan to take it and any site recommend?

No it will not be usable. 850nm is only used for multimode fibre. You need a single mode 1310nm LR (long range e.g 10/20Km) SFP. Mikrotik’s can take generic SFP’s or Mikrotik branded SFP’s and some branded SFP’s. For a Cisco nexus you would want original if you want “support” or get a coded one from fs.com if TAC support is not important.
