[Ronja] Modulation at lower frequencies, CdRom lasers.

[Saad Shakeel]

Greetings every one,
   
  I was wondering that can we modulate the Ronja at a frequency lower than 1Mhz?
  Would it still remain ethernet compatible (slowing of data rate not a problem here)?
  I just cannot find any LED here with less than 1 microsecond risetime.
   
  Some one suggested that i use the laser diode of a Cd Rom. Ignoring the safety concerns for a while, i'm sure it can handle the higher modulation speeds but i'm not too sure about the changes we'll have to make in the circuits and the resulting range of it?
   
  Any ideas?
   
  Thanks,
   
  Saad
