Negative Positive
Title: Works good until they go South
Review: We use these for several Fiber connections between our City locations. Problem is it seems when they have been on for "years" and then you take power away from them they seem to never come back up.They do the job but in the past 5 years I have had to replace 6 or 7 units and we ONLY have 6 in production. Haven't tried any others and when I asked could I go to a different brand my answer was to stay with what we have. So I have 2 replacements at all times.....
