Fiber Optic Ethernet Port Specifications
The following details the specifications for fiber Ethernet ports that can be ordered with the RUGGEDCOM
RS940G.
NOTE
• All optical power numbers are listed as dBm averages. To convert from average to peak, add 3 dBm.
To convert from peak to average, subtract 3 dBm.
• Maximum segment length is greatly dependent on factors such as fiber quality, and the number
of patches and splices. Consult a Siemens sales associate when determining maximum segment
distances.
