Typical.
Typical distance. The maximum distance is greatly dependent on factors such as cable type, the number of connectors and
number of splices. Consult a Siemens sales associates when determining maximum distances.
Gigabit Ethernet (1 Gbps) Optical Specifications
Note
These transceivers utilize a distributed feedback (DFB) type laser and are rated for -20
to 85 °C (-4 to 185 °F) operation only.

All optical power numbers are listed as dBm averages.
Typical distance. The maximum segment length is greatly dependent on factors such as fiber quality, and the number of
patches and splices. Consult a Siemens sales associates when determining maximum segment distances.
