The media converter can be connected to either
of the EQP controller RS-485 communication
ports (Port 1 or Port 2). Figure 3-14 illustrates
a typical Class B wiring connection (single
mode) between two EQP controllers in a
redundant configuration using Port 1. Note: If
Port 2 is preferred, the Serial Interface Board
must be purchased.
Figure 3-13 shows a typical Class X wiring
connection (single mode).
Figure 3-14 shows a typical Class X wiring
connection for Phoenix (multi mode).
For more information regarding selection and
installation of fiber optic media, please contact

The maximum distance of a particular optic
link given the optical budget is calculated as:
Fiber Length = [Optical budget] – [Link Loss]
[Fiber Loss / km]
where link loss includes number of end
connectors, splices and safety margin.
Example: 10 db link budget
Cable Attenuation: 0.4 db / km
2 connectors: (1 each end) with
0.5 db ea.
Safety margin: 3.0 db max
Max. Distance = 10 – (2 x 0.5) – 3.0 = 15 km
