Yeah, you can get up to 80km on a passive unit using SFP+ and up to 120km =
using XFP. =A0To cover the distance you are considering, you would need to=
insert an amplifier. =A0Depending on the number of channels you require, =
a passive solution with an amplified would still be less expensive than an=
active solution. =A0When I was conducting my research, I could not find a=
