State Meaning Remedy
On Monitoring of incoming fiber optic cable. If the
previous participant
•
has optical line diagnostics, the system
reserve for optical transmission has been
exceeded
• does not have optical line diagnostics, a
control of the optical transmission power is
not possible
Check the incoming fiber optic cable for cable
quality, correct connector installation, bending
radius, etc. Use the special optical diagnostics
of the CMD tool or a fiber optic measurement
instrument for further localization of faults.
Off Incoming fiber optic cable is functioning
properly -
State Meaning Remedy
On Monitoring of continuing fiber optic cable. If the
next participant
•
has optical line diagnostics, the system
reserve for optical transmission has been
exceeded
• does not have optical line diagnostics, a
control of the optical transmission power is
not possible
Check the continuing fiber optic cable for
cable quality, correct connector installation,
bending radius, etc. Use the special optical
diagnostics of the CMD tool or a fiber optic
measurement instrument for further
localization of faults.
Off Continuing fiber optic cable is functioning
