Dears,

We have 12 SFP from Finisar RJ-45 (FCLF-8521-3 1000BASE-T 1.25GB / S) connected to our CCR-1016-12S-1S, but none link at Huawei Switch or Notebook).
The CCR-1016-12S-1S identifies the SFP's has (Vendor Name: FINISHER CORP., Vendor Part Number: FCMJ-8521-3, Vendor Serial: PJ2392X) but does not link!

I tested with Auto Negotiation, No Auto Negotiation, I forced 1000M full (on both sides), 1000Mb Half and not working.

Has anyone used this interface?
Did you have to do any special configuration?

The RouterOS version of CCR is 6.45.1 (stable).

Thank you!

The solution was.

Keep each SFP with a following configuration:
- Disable Auto Trading
- Tx Flow Control = Off
- Rx Flow Control = Off
- Speed = 1000M-full
- Auto Trading = no

After
- Disable and Enable all SFP's again;
