I understand that they use different frequency ranges, but why can't the DSL freqencies be converted and sent over fiber somewhere between the CPE and the DSLAM ? On Thu, Dec 10, 2009 at 11:41 PM, Dmitry Kiselev dmi...@dmitry.net wrote: Hello! On Thu, Dec 10, 2009 at 08:48:27PM -0800, Yuri

[c-nsp] DSL signals vs DOCSIS

2009-12-10 Thread Yuri Bank
Why can't DSL signals pass through fiber optics, yet we have HFC networks that obviously have no issues going from copper to fiber. The modulation techniques DOCSIS and DSL use are similar, so what prevents this from working with DSL? Is it that the RF is to weak and the conversion process messes
