Connecting the fiber cables
.................................................................................................................................................................................................................................
Overview
This section provides a procedure for establishing a network via fiber connections from
NE to NE. A protected ring configuration will be used as example. However, the
procedure described below is in principle also valid for other network topologies.
Safety
DANGER
Laser hazard
LambdaUnite
®
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.
CAUTION
Destruction of the detector diodes caused by too high an input
power.
Connecting the input ports of optical circuit packs with a transmit power exceeding the
maximum overload values (see chapter 1, section
“Optical circuit pack specifications”
) will cause the destruction of the detector diodes, as the input power is then
too high.
Where an overload has been detected replace the existing LBO by an appropriate one
(see appendix A, section
“Replacing LC-type LBOs” (p. A-23)
CAUTION
ESD hazard
Electronic components can be destroyed by electrostatic discharge.
Always observe the ESD instructions (cf.
“Electrostatic discharge” (p. 1-20)
