Bending radius
NOTICE
Risk of cable break
As a result of too small a bending radius, optical fiber cables may break.
To avoid cable break, ensure that the bending radius of optical fiber cables is not less
than 38 mm [1.5 inches] or 20 times the diameter of the cable (whichever is greater).
Risk of fire due to overheating
Inadequate heat dissipation can cause heat accumulation or even a fire in the network
element.
You must therefore ensure that:
• the fan unit is installed,
• the individual fans are not obstructed,
• the minimum separation is maintained between two shelves in a rack (follow the
installation instructions given in the 1675 LambdaUnite MSS Installation and
System Turn-up Guide).
Detector diodes
NOTICE
Destruction of the detector diodes caused by too high an input power
Connecting the output and input of optical circuit packs with a transmit power in excess
of -3 dBm over short distances will cause the destruction of the detector diodes, as the
input power is then too high.
Use an optical attenuator pad of approx. 10 to 20 dB when establishing connections over
short distances for test purposes.
