Connecting the fiber optic cables (SC duplex)

WARNING: Danger of eye injuries
During operation, do not look directly into the
transmitter diodes or use optical aids to look into
the fiberglass! The infrared light is not visible.
NOTE: Malfunction
Do not exceed the following FO lengths:
– 22 km with F-G 62.5/125; 0.8 dB/km
– 27 km with F-G 50/125; 0.7 dB/km
– 45 km with F-E 9/125; 0.4 dB/km
Avoid contamination.
Do not remove the dust protection caps until just
before the connectors are connected.
When using fiber optics, observe the fiber optic
installation guidelines, DB GB IBS SYS FOC
ASSEMBLY, Order No. 9423439.
Standardized SC duplex connectors are used with the
PSI-MOS-RS232/FO 1300 E.
Figure 14 Fiber optic connection
• Connect the fiber optic cable to the SC duplex connec-
tor for the transmit and receive channel. Push the con-
nector down until it you hear it snap into place.
Due to the integrated optical diagnostics, there is no need to
measure the path.

When connecting two FO converters, note the signal direc-
tion of the fiber optics:
– Fiber connection "TD" (transmitter) at device 1
– Fiber connection "RD" (receiver) at device 2
Please note the transmit and receive channel
crossover.
Due to different operating wavelengths,
PSI-MOS-RS232/FO 660 ...,
PSI-MOS-RS232/FO 850 ... and
PSI-MOS-RS232/FO 1300 E
devices should not be connected directly with one
another via fiber optic cables.
