Hi guys.
I'm trying to connect 2 switches between 2 sites (300m far away each other), on the main site I'm using CRS328-24p-4s+rm with S-31DLC20D SFP, the other site is JetNet 3705f Switch with 1 x 100 Base-FX, both devices are using wavelength 1310nm (single mode). The problem is on Mikrotik sfp port show run but the traffic can not go through sfp (there is no Rx traffic). Is there any one who have faced this problem? Thank for your advice.
