4. D is the effective diameter of the detector image on the plane of the fiber face. The numerical value is the product of the actual
detector diameter and the lens magnification.
5. Measured at the end of 100/140
μ
m fiber optic cable with large area detector.
6. Propagation delay through the system is the result of several sequentially-occurring phenomena. Consequently it is a combination
of data-rate-limiting effects and of transmission-time effects. Because of this, the data-rate limit of the system must be described in
terms of time differentials between delays imposed on falling and rising edges.
7. As the cable length is increased, the propagation delays increase at 5 ns per meter of length. Data rate, as limited by pulse width
distortion, is not affected by increasing cable length if the optical power level at the receiver is maintained.

Note 4
CAUTION: The small junction sizes inherent to the design of these components increase the components’
susceptibility to damage from electrostatic discharge (ESD). It is advised that normal static precautions be
taken in handling and assembly of these components to prevent damage and/or degradation which may be
induced by ESD.
