Minimum link performance is projected based on the worst case specifi cations of the HFBR-15X7Z transmitter, HFBR-25X6Z receiver, and POF cable, and the typical performance of other components (e.g. logic gates, transistors, resistors, capacitors, quantizer, HCS cable). 4. Typical performance is at 25°C, 125 MBd, and is measured with typical values of all circuit components. 5. Standard cable is HFBR-RXXYYYZ plastic optical fi ber , with a maximum attenuation of 0.24 dB/m at 650 nm and NA = 0.5. Extra low loss cable is HFBR-EXXYYYZ plastic optical fi ber, with a maximum attenuation of 0.19 dB/m at 650 nm and NA = 0.5. HCS cable is HFBR-H/VXXYYY glass optical fi ber, with a maximum attenuation of 10 dB/km at 650 nm and NA = 0.37. 6. Optical Power Budget is the diff erence between the transmitter output power and the receiver sensitivity, measured after 1 meter of fi ber. The minimum OPB is based on the limits of optical component performance over temperature, process, and recommended power supply variation. 7. The Optical Power Margin is the available OPB after including the eff ects of attenuation and modal dispersion for the minimum 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 fi xed passive losses (such as in-line connectors) in addition to the minimum specifi ed distance. 2

Average optical power is measured with an average power meter at 50% duty cycle, after 1 meter of fi ber. 2. To allow the LED to switch at high speeds, the recommended drive circuit modulates LED light output between two non-zero power levels. The modulated (useful) power is the diff erence 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 defi ned as one half the slope of the average power versus duty cycle: [P @ 80% duty cycle - P @ 20% duty cycle] Average Modulated Power = avg avg (2) [0.80 - 0.20] 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 “hold-on” current, is prebias supplied to the LED during the off state to facilitate fast switching speeds. 3
