Hi Forum,

i want to connect a RB2011UiAS-2HnD and a CRS210-8g-2s+IN using LWL. Therefore y bought 2 Mikrotik S-85DLC05D, one for each router. But i'm not able to establish a link between the 2 Routers.

CRS210 shows me on interfaces / ethernet / sfp-sfpplus1 / status a link, but RB2011 don't. RB2011's yellow led above the blue one also don't shine.

After further testing, using a allnet switch using a sfp, RB2011 shows the link and works over the lwl connection. but CRS210 don't work.

So i think my problem is on CRS210's side.

Is S85DLC05D the right sfp-module for usage on CRS210 for a 1GB Link to RB2011?

The same problem , works within two 260gsp, when plugged CCRS light sfp is on but not pass data , we've tried uncencking Auto-negotiation. upgraded to lastest firmware 6.28
