Fiber Optic Ethernet Port Specifications

The following details the specifications for fiber Ethernet ports that can be ordered with the RS900G.
NOTE
• 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.
• 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.
• All cabling is duplex type unless otherwise specified.
