Operating mode ”Redundant optical ring“
CH3 is activated in this operating mode
if S3 and S4 are in Position 1.
CH2 is activated in this operating mode
if S1 and S2 are in Position 1. Note: This operating mode must always be set at both of
the optical channels of a repeater.

4.6.3 Reducing the optical transmitting
power
Attention! The following details only apply for the
S7 default position (S7 = 0)!
The OZD Profi 12M P1x PRO and OZD Profi 12M G1x
(EEC) PRO have a high level of optical transmitting
power. Optical overloading may result if these repeaters
are connected with non-OZD Profi devices using plastic
optical fiber cables, particularly if short cable lengths are
used.
In this case the optical transmitting power can be
reduced. The DIL switch S5 is used to set the transmitting power
of CH2 .
The DIL switch S6 is used to set the transmitting power
of CH3 .
Leave S6 in Position 1 (default) if the
optical fiber link to CH3 functions
correctly in this position.
Leave S5 in Position 1 (default) if the
optical fiber link to CH2 functions
correctly in this position. Switch S6 to Position 0 (reduced) if over-
loading is detected at a non-OZD Profi
device at CH3.
Switch S5 to Position 0 (reduced) if over-
loading is detected at a non-OZD Profi
device at CH2.

Notes:
- When using OZD Profi 12M G1x-1300 (EEC) PRO,
transmission power must be set to Default (S5/S6 in
Position 1).
- When using PCF fibers, transmission power must be
set
- to Default (S5/S6 in Position 1) for 660 nm
- to Reduced (S5/S6 in Position 0) for 850 nm.
- S6 has no function on devices with only one optical
channel.
