Hi, I had two orders for the SFP+ modules S+85DLC03D 300m from the same dealer, the difference between those orders around 6 months
The modules look different and information about the modules from winbox is different
Module #2 have a label on it says that it is for 300m but from winbox its an 80m

If you have any suggestion, why the same model and the same revision are so different, please share it here

Please take look at two different S+85DLC03D

• Link Lenght 50um: 300m vs 80m
• Link Lenght 62um: 150m vs 30m
• Vendor, Themperature, SN format
• Design

* Please take a note that the serial numbers are different from the winbox screenshot and photos because I took photos of same but unused modules

It is weird. I have 4 modules, just like the ones You thought fake. They are about 2 and half years old now, and working perfectly.

Also, take a look at the official wiki:

Run a search for "STST". It is exactly what I see with the four I have. Never though about the sfp-link-lenght, since mine are just 50 meters long.

Thank you, yeap, this is weird, anyway I also have only a few meters, so there are no difference 300 or 80 m for me

I have the same situation: two modules with same vendor part number, but different parameters. Is it Official Mikrotik or fake?
