5.5 Fiber Optical Specifications
The following sections detail fiber optical specifications on ports that can be ordered with the
M2200 series Ethernet switch. The user determines the type of optics at time of ordering, and can
determine the modules installed on a particular unit by reading the factory data file via the
RuggedSwitch ROS
TM
user interface. The following sections detail specifications of fiber optic
modules in Gigabit Ethernet (1000Mbps).
5.5.1 Gigabit Ethernet (1000Mbps) Modules
For maximum flexibility RuggedCom Inc. offers a number of different transceiver choices for
Gigabit fiber optical communications. The following table details fiber optic specifications based on

NOTES:
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 cabling is duplex type unless otherwise specified.
3. All optical power numbers are listed as dBm averages.
4. These transceivers utilize a distributed feedback (DFB) type laser and are rated for -20°C
to +85°C operation only.
