Re: [AFMUG] Outdoor PON OLTIn the olden days, 20km restriction was related to timing delay.

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. When doing active Ethernet you can come in closer to $100 per customer. For non regulated greenfield, I am having a hard time convincing myself to do PON.

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. I was figuring on several small splitters along the route. I didn't compare to a 1x32 in the cabinet because I figured if I brought every fiber back to the cabinet then I didn't save anything versus ethernet. ------ Original Message ------ From: "Mark - Myakka Technologies" <m...@mailmt.com> To: "Adam Moffett" <af@afmug.com> Sent: 2/12/2018 11:30:46 AM Subject: Re: [AFMUG] Outdoor PON OLT Adam, How far are you going? We are pushing almost 20 miles on a 1x32 split. Are you using one 1x32 or multiple smaller splitters? -- Best regards, Mark mailto:m...@mailmt.com Myakka Technologies, Inc. www.MyakkaTech.com ------ Sunday, February 11, 2018, 10:24:30 PM, you wrote: I'm looking at rural areas (like a few houses per mile). 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.
