Notes:
1. If the output of U4C in Figure 1, page 4 is transmitted via coaxial cable, terminate with a 50
2. Run length limited code with maximum run length of 10 s.
3. Minimum link performance is projected based on the worst case specifications of the transmitter, receiver, and POF cable, and the
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

available for long term LED LOP degradation and additional fixed passive losses (such as in-line connectors) in addition to the
minimum specified distance.
