Link Budget Examples
Cable
Typical transmit couple power to fiber (µW)
Minimum LED responsivity (A/W)
Available current (µA)
Minimum ACS103 sensitivity (nA)
Link Budget (dB)
Above examples using nominal "B" spec. LED diodes. "A" spec. LEDs offer superior performance, e.g. > 12 dB link budget
on 50 µm fiber. "A" spec. LEDs are available from Acapella.
Input current is mainly attributed to pull-up resistor, so it applies when input is Low. The High input current is <
