Hello,
I have installed two 1000BASE-LX/LH SFP (GLC-LH-SM) each with Cisco SF300-24 and Cisco 2960 in order to establish a backbone connectivity between two departments. The distance between the two departments is around 600 metres
Normal Ping Response is fine as per the below output (highlighted in GREEN):
