Background information

The 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

1643 AM/AMS 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.

"Laser safety" (p.

Proceed as follows to establish a network:

...................................................................................................................................................................................................

Connect an optical fiber to the OUT port of interface LP1.1 or LP2.1.

...................................................................................................................................................................................................

Move to the next NE. At the IN port of the respective optical interface (LP1.1 or

LP2.1) measure the received optical power from the far-end transmitter.

Important! The optical power meter must be set to the appropriate wavelength

range.
