Chapter 2: Installation and Operation
CAUTION
To prevent overload damage, ensure that you observe the
following:
Harris Corporation does not recommend installing 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.
The input power on the high-sensitivity receivers must not exceed
0 dBm. To ensure error-free operation, the input power must be less
than -7 dBm.
