Single or Multi Mode

Short Range MultiMode, 850nm, LC

Thanks , and for " F5-UPG-SFP+LR-R " it is Single , right ?

 

if i have both types , which is better for traffic interfaces & which is better for HA interfaces ?

 

Indeed it is. There's no difference in performance, just maximum distances. MM is usually a bit cheaper, both for optics and cables.
