Fiber Optic Ethernet Port Specifications
The following details the specifications for fiber optic Ethernet ports that can be ordered with the RUGGEDCOM
RMC.
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.

Supported Networking Standards
IMPORTANT!
The RUGGEDCOM RMC features Link Pass Through support. When loss of link is detected on either the
fiber side or the copper side, link pulses are no longer transmitted on any of the RUGGEDCOM RMC
ports. This feature allows for prompt loss of link detection and user correction.
