tion while the source is operating at the minimum intensity in angular range into the minimum half-angle range at the maximum Link Length.
***)
maximum intensity in angular range at Minimum Link Length must not cause receiver overdrive distortion and possible related link errors.
If placed at the Active Output Interface reference plane of the transmitter, the receiver must meet its bit error ratio (BER).
For more definitions see the document “Symbols and Terminology” on the Vishay Website (http://www.vishay.com/docs/82512/82512.pdf).
