Procedure 8-8: XC and CTL protection test
Overview
This test verifies the XC and CTL 1+1 equipment protection functionality.
OTE: This test should only be performed if XC and/or CTL 1+1 equipment protection is
used.
Safety
1675 LambdaUnite MSS systems operate with invisible laser radiation. Laser radiation
can cause considerable injuries to the eyes.
ever 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.
Connecting the input ports of optical circuit packs with a transmit power exceeding the
maximum overload values (see chapter 1, section
(p. 1-14)) 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
Electronic components can be destroyed by electrostatic discharge.
Always observe the ESD instructions (cf.
