Re: Verizon Bites CableCard Bullet (New Set Top Boxs)
said by rashid11  :FIOS' all-optical network means very low SNRs which translates to QAM-256 - giving FIOS the fattest pipe and they are not quite starved for BW like satellite companies are, for example. That's not the main benefit. Most cable operators do 256QAM as well. Just Fios saves the bandwidth that cable operators would use for VOD, Internet, and Voice, since those services are on it's on wavelength carried via IP.
Not to mention its a 54-864 MHz output, when many cable systems only go to 750 MHz.
My area for example has 4 256QAMs for VOD, and one for HSI/Voice. That's 5 QAM slots that could be saved if they were on a different fiber/wire/wavelength/etc....
Some area's have even more QAMs for VOD and Data. Sure the SNR is great, but no ones pushing 1024QAM.... |
