Connecting the fiber cables
....................................................................................................................................................................................................................................
Background information
The LC attenuator which will be determined in the procedure
described below should be placed on the INPUT port because this is
the furthest physical point on the fiber line from the OUTPUT port
and takes all connector losses into account.
Before you begin
Be sure that all fiber connectors are clean. A cleaning procedure is
described in Appendix A, section
Procedure
DANGER
Injury to eyes caused by invisible laser radiation.

™
MSS systems operate with invisible laser
radiation. Laser radiation can cause considerable injuries to
the eyes.
Never look into the end of an exposed fiber or into an
open optical connector as long as the optical source is
switched on. Always observe the laser warning
instructions (cf.
Proceed as follows to establish a network:
............................................................................................................................................................
1
Connect an optical fiber to the OUT port of one optical circuit pack.
............................................................................................................................................................
2
Move to the next NE. At the IN port of the respective optical circuit
pack measure the received optical power from the far-end transmitter.
Important! The optical power meter must be set to the appropriate
wavelength range.
..........................................................................................................................................................
3
Check that the measured value is within the range shown below (see
section
“Optical power and wavelength ranges” (8-8)
