29、4x4Z LED transmitter. With I F= 48 mA the HFBR-14x4Z/24x2Z logic link is guaran- teed to work with 62.5/125 m ber 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 1= 115
30、, the transmitter can be driven with I F= 30 mA, if it is desired to economize on power or achieve lower pulse distortion. The following example will illustrate the technique for selecting the appropriate value of I Fand R 1 . Figure 2. Typical Circuit Conguration. +5 V SELECT R 1TO SET I F R 1 I F

TOTAL LEAD LENGTH BETWEEN BOTH ENDS OF THE
32、CAPACITOR AND THE PINS SHOULD NOT EXCEED 20 MM. Maximum distance required = 400 meters. From Figure 3 the drive current should be 15 mA. From the transmitter data V F= 1.5 V (max.) at I F= 15 mA as shown in Figure 9. The curves in Figures 3, 4, and 5 are constructed assum- ing no inline splice or an
33、y 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 m ber 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. = - = - = 233 R mA 15 I 1.5V 5V V V R 1 F F CC 1
