In addition, all fiber optic connections must be inspected and cleaned before they are
assembled. Carefully follow the inspection and cleaning steps described in the next pages.
Additional safety information appears in
Laser Safety on page 95.
CAUTION: Ensure that you remove the fiber optic protective covers from the front
and back modules before installation. Take care to avoid touching the fiber optic
connections. Thoroughly clean the connections before installation. Remove power
from the frame before installing or removing back modules.

CAUTION: To prevent overload damage, ensure that you observe the following:
For best results, do not install high-sensitivity (APD) optical receivers on multimode
fiber. Due to its dispersion characteristics, multimode fiber is typically limited to
shorter distance applications with very little signal attenuation. The resulting
power levels may damage the receiver.
Before connecting any standard-sensitivity (PIN) or high-sensitivity (APD) optical
receiver to a fiber network, ensure the power level is tested to fall within the
published specifications of the receiver. Failure to verify optical power before
connection will void the warranty.
To ensure error-free operation, the input power must be less than -7 dBm.
