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.
