Will modulating an IR LED at higher frequency reduce its range? If so, why?
You won't have reduced range if you use parts and circuit suitable for 15 MHz modulation. They just needs to be quite performant parts and circuits, carefully selected and designed. For example ...

Will modulating an IR LED at higher frequency reduce its range? If so, why?
The modulation frequency must be in the receiver's capture range,
and most receiver designs are wideband. That implies that
a high modulation frequency is associated with wideband receiver noise

Communication protocol for using 2 pairs of CAT 5 cable
Cat5 cable has four pairs; you can use two pairs for Ethernet,
or for POE (power over Ethernet) and network, and one pair for
video of the analog type (PAL or NTSC if it has to be in color).
USB isn'...

Communication protocol for using 2 pairs of CAT 5 cable
RS-485 also does not convert to USB, and USB can't pass through more than 5 meters in any case, and CAT5 has incorrect impedance for USB.
Send the video as analog over one pair. Use second pair for ...

Confused about the right sequence or order of receiver DSP functions
There's different equalizers and different phase, timing and frequency recovery method, and the order depends on which ones you use.
For example, a decision feedback equalizer necessary happens after ...
