    Our company is just about to roll out multi gig speeds (1, 2, & 5 Gbps) via FTTP, and we are already looking at increasing our HFC top tier speeds as well (we currently offer 1 Gbps X 50 Mbps via Coax and I believe are looking to possibly go 2Gbps X 100 (ish) Mbps.

      Thanks for the details @BillyWilliamsJr your company is doing great things! Keeping up with subscriber demand is more than a full time job, but offering 2 Gbps x 100 Mbps is certainly in the right direction.

    we mostly use the eero products for a separate wifi device so the modem doesn't need to be replaced. the hitron wifi modems are put in small homes, and mdu that only get the basic 350mbps speeds. my areas have most customers just getting the 350 with only a few getting the 1gig for cost reasons. upstream congestion is still the biggest issue with trying to keep our nodes small. node 0 and node +1 has been our upgrades for almost 10 years now. i don't know anything about the r-macphy being done in my small systems, and seems our engineering dept doesn't know how to implement it either. i just know there is a pallet on its way to me with the gear. i think we will just do maybe 100mbps up and 1 gig or more down as it would be a big expense to swap all the actives for such a small customer base in a small town. i'm not sure how much the equipment costs, but not having a 5k/mo power bill for the headend should pay for it in savings pretty quick.

      Hi @sragga 1 Gbps down and 100 Mbps up seem to be the standard this year. That is fantastic that you guys are doing it. Thanks for watching and best of luck on the new gear. Keep us updated on the progress.

      ​@@Volpefirmthat's interesting cuz the cable co that I contract for offers 1.5 down & 150 up. Strangely, my Hitron DP3 (aka XM2) speed test results Show 2 gig down & 200+ up!

      That is great news @grabasandwich. As we discussed in the video, 1 out of 3 homes now have 1 Gbps speed. Seeing operators provide more than 1 Gbps down and 100 Mbps up is great to see. The OVBI data definitely shows that our super power users will consume it. As in the movie Field of Dreams - "if you build it, they will come" 🙌

    I wanted to know if you guys have any experience working around nodes designed to run fiber to the premise and use an RFOG to convert light to coax at the side of the home. Unlike GPON style networks where the fiber feeds directly to the gateway.

    • @Volpefirm
      @Volpefirm  2 місяці тому

      Hi @Jlogo yes, we have worked with RFOG before. It does not play well with OFDMA in the upstream. OFDM in the downstream works fine, but RFOG does not support OFDMA.

      @@Volpefirm Great videos! They are definitely helping me understand the intricacies of the industry not just the what happens more so about why it does. I’m struggling with RFOG systems and finding noise on occasion. It’s often either really easy to find or dang near impossible.

    As a residential contractor, I feel like they're beating a dead horse by trying to exploit the existing coax any further. At least it's not twisted pair, but the coax in many areas I work in is horrible condition. Couple that with what seems to be Reactive Network Maintenance (see what I did there? 😉) and its no wonder so many of my customers are having a terrible experience. Granted, there are a lot of variables within the home, but there seems to be a ton of repeat troubles that I feel are plant issues. But they're so intermittent, and I don't have the training or resources to pinpoint that. So then we got multiple techs going out, swapping equipment, replacing cables and changing ends till we're blue in the face...
    I heard rumors that the company might be abandoning HFC, but like the telco, it'll take YEARS to roll that out.

      Hey @gabasandwich, this is a whole topic 😁 Short story. Cable is already run the to home, yes it sucks, but its there. Fiber is expensive and labor intensive to run and test. Next to you need to convince each and EVERY subscriber to switch over. Every modem needs converted to an ONT. Test equipment changes. Existing video distribution needs to change. Provisioning needs to change. And so on. The lift and cost becomes huge. Suddenly the coax in the ground looks really good again. Everyone decides "we can make it work a little longer". Fiber - next year. And here we are again. :) BTW, the in home wiring issues you face will be the same with fiber. The ONT just replaces the cable modem. You have job security :)

      i personally lived in a neighborhood that had persistent upstream reductions in SNR/performance, it never got fixed in the whole 5 years i lived there. This was maybe 2013-2018. I eventually had to move. My newest place is the same ISP and has occasional bursts of uncorrecteds on the downstream but is lights years better and actually reliable for WFH.

    16:40 I have a question. I understand that congestion has mostly become a thing of the past (where I am) but don't ISPs use some form of traffic shaping (or whatever the proper term is) to help prevent those abusing or saturating their connection? I know very little about transport, etc but as a residential tech, I see a lot of weird, intermittent issues where I can't find anything wrong, nor can I prove it's back end related. It's so frustrating.

    • @Volpefirm
      @Volpefirm  8 місяців тому

      Hi @grabasandwich cable operators used to implement a lot of "throttling" or "fair use" policies, which did exactly what you described. It limited the super heavy users after a point. However, Covid hit. That changed everyones behaviors. So many cable operators stopped throttling (fair use) and have not gone back to using these technologies that are part of DOCSIS, which help manage network congestion, especially during peak utilization hours. It can also help defer node splits, which become problematic during peak hours. Not saying the node doesn't need to be split, but you can't do everything at once, so managing it more effectively so that end users have better QoE is a step in the right direction from my perspective.

    Funny to see John's complete reversal on upload speeds, and he now claims he's been "evangelizing" higher upload speeds lol. In your own video from 3 years ago ("The Road To DOCSIS 4.0") he becomes irate at the suggestion of anyone needing higher upload speeds, and says symmetrical is completely unnecessary. "Why?? Why would anyone need that?!" he shouts.
    Well... we now have every cable company in North America doing mid-split, high-split, or DOCSIS 4.0.
    Funny for him to act like he's always been on this page, when he was saying exactly the opposite 3 years ago... and it's on video!
