None of he cable Internet systems I know use higher than 900 MHz 
frequencies. 

The cable Internet connections typically use normal TV brodacasting 
frequencies (or frequencies between normally allocated channel 
freqencies) in 110-900 MHz frequency range for data going to users
(typically a group of cable modems share on around 5-6 MHz wide 
channel on the cable). 
The data from user to head end uses lower frequencies, 
typically from 5 Mhz to 30 or 60 MHz (the upper level depends on 
the system used). 
 
So a properly designed splitter designed up to 900 MHz would be 
more than sufficient for cable data applications. That't for 
what the other components in the cable TV system are designed for.
