Re: Advanced Fiber Network claim said by JRW2:Excuse me?? Hybrid fiber network, or fiber to the home.... Hmmmm, I wonder which ACTUALLY delivers faster speeds, and which can consistently deliver them?? That has everything to do with network design, and very little to do with the underlying transport technology. The MSOs could scale down to 16-32 homes per HFC node and easily go head-to-head with FiOS, if they had reasonable justification to make the investment.
Case in point: into the home from the ONT, even FiOS is copper via either MoCA or Cat5. The transmission medium does not matter -- the design and scaling of the network do.
said by JRW2:I would also add, which has a better PQ than the other... On digital transmissions it's not going to make a huge difference. Few are foolish enough to suggest that 1s and 0s are "sharper" on fiber than copper.
said by JRW2:And to add the FINAL nail in the coffin, which company offering high speed internet/TV/Phone, OWNS a huge amount of the internet backbone that all data travels on???? Verizon Business / UUNet / MCI / Alter.net has a vast network, but it doesn't carry as much traffic as you are implying. With the heavy reliance on providers like Level(3), Global Crossing, and Cogent, Verizon doesn't even rank in the top 5 for traffic volume.
Of course, the backbone operations group is also completely different from the broadband services group. Different balance sheets, different staff, different equipment standards, different call centers, different customer base. The only thing they really share in common is the ticker symbol. | |

00000 | Actually PQ is different on copper or fiber but it goes back to your point of scability. Digital doesn't having any meaning in terms of quality because PQ is subject to compression. I can compress a digital feed so much that it is unwatchable. And when an MSO is trying to 'cram' channels into their limited bandwidth, they'll compress the snot out of it and PQ goes to hell. FTTH, theoretically, having higher capacity means the provider doesn't have to compress the snot out of it to add channels to a line up. | | |

Fiber *IS* better than Copper. Here is the reasons:
1. More bandwidth. Technically, Fiber can handle 1+Tbps connections. Add multiple wavelengths and it'll go even faster.
2. Longer distances. I think 25 miles without a repeater is freakin' awesome.
3. Reliability. No more crappy coax connections and no ugly signal fluctuations.
..and if you want compatibility, you can split your video, data, and phone from the feed and put them in their places (Coax, RJ45, and RJ11).
What's the benefit of Coax to the home?

1 edit | said by Simba7:Fiber *IS* better than Copper. Here is the reasons: I'm not going to dispute that fiber often has advantages over copper on the provider side. What I'm saying is that you, as a customer, sign up for a service based on the features it provides -- be it Internet access speed, number of TV channels, or telephone features. The factors that influence each of those options is only loosely related to the underlying transport medium.
said by Simba7:1. More bandwidth. Technically, Fiber can handle 1+Tbps connections. Add multiple wavelengths and it'll go even faster. The frequency breakdown in FiOS today is using mechanical means (prisms), which means home visits are required and complete ONT swapouts required to tap into additional capacity. So yeah, you can upgrade, but be prepared for a massive bill of materials to accomplish it.
said by Simba7:2. Longer distances. I think 25 miles without a repeater is freakin' awesome. With ZR optics you can go 80km without amplification, but keep in mind that fiber span needs to be absolutely clean. Any bulkhead connections at fiber junction boxes or splice points from recovering cable cuts will substantially reduce that distance. Still, as an end user buying a service, why the heck do I care what the distance benefits are for fiber? I only care if I can get the service or I can't.
said by Simba7:3. Reliability. No more crappy coax connections and no ugly signal fluctuations. True, with fiber you're not going to have to deal with EMI/RFI, transient voltages, or grounding issues. You still have to deal with issues of patch panel termination faults, failed connectors that allow the fiber to spin and change the connection characteristics, and any events that cause the glass to bend beyond specs or break.
Bad events can still occur with fiber: just last month the local DiecTV rebroadcast facility lost 50% of it's capacity when water flooded into a fiber conduit that was cut open when new road signs were placed by the state. After an unusually warm February day, which allowed the snow to melt and flood the conduit, there was an extreme cold snap that followed that resulted in the water freezing in the conduit and snapping the fiber. Since the conduit was also frozen solid, that prevented new fiber from being blown through the conduit as well.
said by Simba7:What's the benefit of Coax to the home? This is easy:
•Large base of infrastructure already installed
•Able to be spliced very cost effectively (no need for fusion splice gear like with fiber) in the event of a break
•Able to be split into multiple feeds using inexpensive splitters
•Less expensive amplification hardware for copper | |

What's the benefit of Coax to the home? 1TBps to your home? Not today, not in 5 years. Probably not even in 10 years. Keep dreaming.
Longer distances, I agree. That is why cable companies run fiber to local nodes and why they are making the nodes smaller now.
Reliability. I agree with that, but to be honest the cable on the poles (hardline) is tough as nails and will last for decades. Besides, with HFC the copper portion of the cable plant is not that big anymore.
Definitely fiber is better. But HFC matches what FiOS is offering today. When they offer something more, cable can step up its game for a lot less cost than FiOS, by running fiber to the home since the longest part of their network is fiber. | |
