HFBR-0507 Series
125 MBd Data Link
Data link operating conditions
and performance are specified for
the HFBR-15X7 transmitter and
HFBR-25X6 receiver in the
Recommended Operating Conditions for the Circuits in Figures 1 and 2.
Link Performance:
recommended transmit and receive application circuits.
Notes:
1. If the output of U4C in Figure 1, page 4 is transmitted via coaxial cable, terminate with a 50 Ω resistor to V
2. Run length limited code with maximum run length of 10 µs.
3. Minimum link performance is projected based on the worst case specifications of the HFBR-15X7 transmitter, HFBR-25X6 receiver,
4. Typical performance is at 25°C, 125 MBd, and is measured with typical values of all circuit components.
5. Standard cable is HFBR-RXXYYY plastic optical fiber , with a maximum attenuation of 0.24 dB/m at 650 nm and NA = 0.5.
6. Optical Power Budget is the difference between the transmitter output power and the receiver sensitivity, measured after
7. The Optical Power Margin is the available OPB after including the effects of attenuation and modal dispersion for the minimum

Extra low loss cable is HFBR-EXXYYY plastic optical fiber, with a maximum attenuation of 0.19 dB/m at 650 nm and NA = 0.5.
HCS cable is HFBR-H/VXXYYY glass optical fiber, with a maximum attenuation of 10 dB/km at 650 nm and NA = 0.37.
1 meter of fiber. The minimum OPB is based on the limits of optical component performance over temperature, process, and
recommended power supply variation.
link distance: OPM = OPB - (attenuation power loss + modal dispersion power penalty). The minimum OPM is the margin
available for longterm LED LOP degradation and additional fixed passive losses (such as in-line connectors) in addition to the
minimum specified distance.
