7.1. Optical Fiber (FO) Connection
1. Connect the optical fiber cable to the B-FOC (ST
)
connector for the send and receive channel and
push the connector clamp mechanism downwards.
2. Secure the connection with a quarter turn to the
right (Figure 11).
General Notes
Follow the cable manufacturer's technical data when
handling the various optical fiber cables. In order for the
communication path to be protected against
interference, the permissible values for the bending
radii, strain, and pressure strengths must not be
exceeded.
ST® is a registered trademark of AT&T.
7.2. Diagnostic Indicators
Link Control Optical Fiber Path (FO):
The line monitoring checks the connected cable
segment for an interrupt. To do this, the partner must
send link or data signals. The LED (green) lights up if
no error has occurred. An interface that is not being
used or a terminal device that is switched off is
indicated as an error and the LED goes out.
Data Control Optical Fiber Path (FO):
The data LED (yellow) flashes depending on the
amount of data that is received by the optical fiber
interface.
Protective caps should only be removed
just before the connectors are
connected. They protect the send and
receive elements. The same applies to
the protective caps for the connectors.
During operation, do not look directly
into send diodes, or use visual aids to
look into the glass fibers. The infrared
light is not visible.
Be aware of the optical fiber cable signal
direction when coupling two medium
converters:
Module 1 fiber connection "TD" (sender)
to module 2 fiber connection "RD"
(receiver).
