1. Maximum segment length is greatly dependent on factors such as fiber quality,
and number of patches and splices. Please consult RuggedCom sales associates
when determining maximum segment distances.
2. All optical power numbers are listed as dBm averages.
3. Distance ratings are typical but will depend on type of cabling, number of
connectors and splices.
4. FG54 and FG73 transceivers have an operating temperature range of -20°C to
+85°C. All other transceivers have an operating temperature range of -40°C to
+85°C.
