From: Chris Fabien Sent: Thursday, February 15, 2018 10:53 AM To: af@afmug.com Subject: Re: [AFMUG] Outdoor PON OLT Chuck, I would love to hear your lower cost idea. Right now we use mainly HDPE handholes, not load rated, and place them so it's unlikely to see heavy traffic. We have had one crushed so far by a tractor, so its not perfect (but the fiber was OKAY). But they are $75ea vs $200 for a polymer concrete, worth having to replace one or two a year. This video I only recently found, but it explains this tapping architecture very well. https://www.youtube.com/watch?v=k78dC2z1mWc I wish I had seen this video 5 years ago. It seemed a lot more "wierd" when we were suggested the idea by another fiber upstart guy. Mark, I've done lots of drawings of distributed splits inside a 12-count main and folding legs back along the mainline and what not. Certainly a viable approach. I think it is overly complicated, especially when at some handholes you are splicing drops to go north and at some you are splicing to go south and what not. I think the tapped trunk layout is working very well for us in our area, certainly has some compromises but I'm happy with it. You do have to have the loss values worked out upfront. If you leave some extra margin you can tolerate cutting in an extra splitter here or there as houses are built and what not. Chuck, its very much same idea as Coax taps in CATV, the math pretty much the same. Chris On Thu, Feb 15, 2018 at 10:44 AM, <ch...@wbmfg.com> wrote: What are you using for handholes? Full traffic rated handholes are a large expense. I am working on a lower cost idea, but if something equivalent to my idea already exists I would rather just buy them.

There's just a range parameter that needs to be set. We ordered C+ optics and see a real optical budget of 33dB. The OLT is about +5.5 tx and -34 min rx sensitivity. The ONU about + 0.5 tx and -28 rx sens. I've been very impressed with the optical performance. We did test the ubnt as well.

The other reason I would think about GPON is that if a larger company wanted to purchase our network down the road I have to think about what THEY will prefer. They'll probably prefer PON. Humans are horrible at assessing their own biases, but I probably have a bias towards ethernet because it's familiar. I try to bear that in mind too. ------ Original Message ------ From: "Chuck McCown" <ch...@wbmfg.com> To: af@afmug.com Sent: 2/12/2018 1:13:18 PM Subject: Re: [AFMUG] Outdoor PON OLT When doing full throttle Calix GPON we have about $570 invested in cpe electronics, splitter, ont/olt/onu etc. Everything but fiber and outdoor cabinets.

From: Mark - Myakka Technologies Sent: Monday, February 12, 2018 9:55 AM To: Adam Moffett Subject: Re: [AFMUG] Outdoor PON OLT Adam, There are some ranging things you have to consider. "The requirement when deploying ONTs are the maximum distance between two ONTs cannot exceed 20Km." The way we have done this is to reuse fibers as we travel down long stretches of roads between neighborhoods. We will deploy a 1x32 splitter in the field. We will splice that into the last 3 ribbons/tubes of our fiber. Example, if we were using a 144 count cable, ribbons 10-12 will be spliced into. After a few miles depending on density or distance, we will splice in another 1x32 splitter to ribbons 10-12. We just keep doing this until we run out of light budget. We build to the lots passed, so we are not trying to optimize max usage per port. Currently, we average about 50% utilization on our ports. -- Best regards, Mark mailto:m...@mailmt.com Myakka Technologies, Inc. www.MyakkaTech.com ------ Monday, February 12, 2018, 11:38:39 AM, you wrote: Maybe I need to review the math.

As I'm looking at hypothetical power budgets for PON, I'm finding that if I run the line down the road and put splitters on the pole I can split 5-6 times and then I'm getting too low on db to keep going down the road. At 5 or so houses per port, a 1U, 8 port ONT is no denser than a 1U switch. Your stated reasons for PON are all correct. The numbers just aren't seeming to work out for me. I also figure if I install enough fibers for AE, I can still switch to PON some day if I want to. We would never max out the PON port, but looking back on the past 15 years of growth in consumption I wonder if I should ever say "never". In AE I can put 100Gig in every house if I have to. I'll "never" have to do that as far as I can imagine, but my imagination could be limited. -Adam ------ Original Message ------ From: "Josh Reynolds" <j...@kyneticwifi.com> To: af@afmug.com Sent: 2/11/2018 9:28:34 PM Subject: Re: [AFMUG] Outdoor PON OLT A few reasons... Port cost is still fairly high. More splicing. More fiber required. Larger chassis required. More power required. More battery backup required. Consumers not even close to using up 1-2 generations back of PON capacity in most places.
