Re: The Network Port on the back of the Ultra TV PlayersThe media players use MoCA, and the signal comes from the gateway. MoCA operates around 1200mhz.
As MoCA works differently than traditional cable television wiring architectures, time must be taken to understand the differences between the two. The basic components of the home network include cable, splitters & amplifiers.
Traditional home wiring cable loss Cable loss RG-6 (@100 feet) 1.0dBmv @30 MHz 1.5dBmv @55 MHz 5.5dBmv @750MHz
MoCA home wiring cable loss Cable loss RG-6 (@100 feet) 7.0dBmv @ 1.2GHz
Splitter loss up to 1 GHz Two Way - 2x 3.5dBmv Three Way - 1x 3.5dBmv & 2x 7.0dBmv Four Way - 4x 7.0dBmv Eight Way - 8x 11.0dBmv
Splitter loss at 1.2 GHz Two Way - about 6dBmv @ 1.2 GHz Three Way - about 10dBmv @ 1.2 GHz Four Way - about 10dBmv @ 1.2 GHz Eight Way - about 14dBmv @ 1.2 GHz
Traditional house amplifiers don't pass MoCA frequencies well if at all in the reverse path, however, do pass the MoCA band reasonably well on the forward path even though the upper band limit indicates a pass band up to 1000MHz.
All MoCA traffic is between a media gateway and up to five media players. In general, the maximum cable distance supported between the media gateway and the media players is about 150 feet or 10dBmv of cable and the maximum splitter attenuation permitted is about 30dBmv or a total link loss of 40dBmV between the media gateway and media players. |
