S-31DLC20DI vs S-31DLC20D

Hi all,

We have ordered some S-31DLC20D SFP modules and received S-31DLC20DI instead. They seem to work fine, but they are physically different from other S-31DLC20D we have. I cannot find any differences on any website, and the S-31DLC20DI is not even on Mikrotik’s site.

Anyone can shed some light?
