Hello we have a fiber link with our ISP but it has some problems of transmission.
From ISP side there is a Cisco GLC-LH-SM= 1000BASE-LX/LH SFP, from our side there is MikroTik S-31DLC20D SFP Dual, 1.25Gbps, SM LC, 1310nm, 20km and the CRS125-24G-1S-RM.
We have big latency to ping the other side (ISP is 1,5 Km distance from us), is there some known incompatibility with Cisco transceiver?
