5 MBd Logic Link Design
If resistor R1 in Figure 2 is 70.4 :, a forward current I
48 mA is applied to the HFBR-14x4Z LED transmitter. With
I
teed to work with 62.5/125 μm fiber optic cable over the
entire range of 0 to 1750 meters at a data rate of dc to 5
MBd, with arbitrary data format and pulse width distor-
tion typically less than 25%. By setting R
transmitter can be driven with I
to economize on power or achieve lower pulse distortion.
The following example will illustrate the technique for
selecting the appropriate value of I
+5 V
NOTE:
IT IS ESSENTIAL THAT A BYPASS CAPACITOR (0.01 μF TO 0.1 μF
CERAMIC) BE CONNECTED FROM PIN 2 TO PIN 7 OF THE RECEIVER.
TOTAL LEAD LENGTH BETWEEN BOTH ENDS OF THE CAPACITOR
AND THE PINS SHOULD NOT EXCEED 20 MM.

DISTANCE =
Maximum distance required = 400 meters. From Figure 3
the drive current should be 15 mA. From the transmitter
data V
The curves in Figures 3, 4, and 5 are constructed assum-
ing no inline splice or any additional system loss. Should
the link consists of any in-line splices, these curves can
still be used to calculate link limits provided they are
shifted by the additional system loss expressed in dB. For
example, Figure 3 indicates that with 48 mA of transmit-
ter drive current, a 1.75 km link distance is achievable
with 62.5/125 μm fiber which has a maximum attenua-
tion of 4 dB/km. With 2 dB of additional system loss, a
1.25 km link distance is still achievable.
