Plastic Optical Fiber (1 mm POF) Transmitter Application Circuit: Performance of the HFBR-15X7Z transmitter in the recom-
mended application circuit (Figure 1) for POF; 1-125 MBd, 25°C.

mended application circuit (Figure 1) for HCS; 1-125 MBd, 25°C.
Notes:
1. Average optical power is measured with an average power meter at 50% duty cycle, after 1 meter of fiber.
2. To allow the LED to switch at high speeds, the recommended drive circuit modulates LED light output between two non-zero power levels.
3. High and low level LED currents refer to the current through the HFBR-15X7Z LED. The low level LED “off” current, sometimes referred to as

The modulated (useful) power is the difference between the high and low level of light output power (transmitted) or input power (received),
which can be measured with an average power meter as a function of duty cycle (see Figure 3). Average Modulated Power is defined as one
half the slope of the average power versus duty cycle:
“hold-on” current, is prebias supplied to the LED during the off state to facilitate fast switching speeds.
Average Modulated Power =
