| So, does this actually do anything for the consumer? From a quick Wikipedia scan (google rfog site:wikipedia.org), it appears the only advantages are:
1) ability to run PON concurrent with RFoG on the same fiber
2) better quality line
So, to the consumer, unless the carrier actually installs optical equipment, it's exactly the same as DOCSIS over good coax. yes?
It seems this is only valuable to the carrier as a path to future "true fiber" connections. |

Jewett City, CT | Yes and no. As you mentioned the big benefit is having a medium to every home that is almost unlimited in terms of future bandwidth demands. Reliability comes in the form of fiber, less "moving parts" between the customer and the source, and also battery backups at each home.
In the short term it matches the same amount of bandwidth most PON systems like FIOS use for video service (860Mhz) and still has capacity left over for ~24 bonding channels for DOCSIS 3 which equates to ~1Gbit/sec of bandwidth. To put that into perspective most of the DOCSIS 3 deployments today that are competing with GPON/FIOS are only 4 or 8 channels. So it addresses both short and long term bandwidth demands. I'm guessing in most cases the long term upgrade path will be 10G-EPON instead of GPON. |

As for the 'only' advantages:
3. Analog is King. NO VIDEO COMPRESSION.
4. Immunity to interference.
5. Future proof technology.
to name a few. |

Plus no more "overloaded" nodes. Everyone has their own node/38 dwn 27 up DOCSIS bandwidth pool. |

When I had Road Runner, they could never get me a good stable low-error connection, in three different houses in Austin.
3. Analog is King. NO VIDEO COMPRESSION.
Compression and analog/digital are orthogonal. You can have uncompressed digital or compressed analog. In general, all else being equal, digital is better than analog for many reasons. This is one of the things AT&T got right with U-verse, everything's a digital IP stream.
4. Immunity to interference.
5. Future proof technology.
yep. |
