Re: [AFMUG] DWDM/CWDM Magic
Both. However, when they're providing regen, you're not really getting dark fiber anymore, you're getting spectrum as a service. You don't get a 1 gigabit or 10 gigabit wave, you're getting 100 GHz, 112 GHz, 200 Ghz, etc. - Mike Hammett Intelligent Computing Solutions Midwest Internet Exchange The Brothers WISP - Original Message - From: "TJ Trout" To: "AnimalFarm Microwave Users Group" Sent: Tuesday, May 7, 2024 12:33:00 PM Subject: Re: [AFMUG] DWDM/CWDM Magic Purely for curiosity what if you want to lease a span that requires Regen?

Re: [AFMUG] DWDM/CWDM Magic
This non-profit joint exists due to ARRA funding. At the time I was annoyed that they got money for middle mile that doesn’t serve anybody and we didn’t get funding for our wireless project that actually *would* serve people. In hindsight I don’t mind them being there. We looked at an IRU for 48 fibers for one mile to get around a bad make-ready situation. They said they’d have to include a non-recurring charge for an overlash because 48 would consume everything they had left on the cable and make all the miles before and after that point worthless. Even with the overlash cost it was an order of magnitude cheaper than building it ourselves. Instead we leased one fiber and we’re building a small POP. That’s less CapEx but more OpEx to maintain another site, and powers higher than me think that’s better in this case. …..and either way having them available saved the day. I’ve seen much higher quotes for IRU’s and often times, like you said, they’re high enough to be comparable to building it yourself. I think they sell I to people who don’t want to own plant, or people who need to execute immediately. -Adam From: AF On Behalf Of Chuck McCown via AF Sent: Sunday, May 05, 2024 7:03 PM To: AnimalFarm Microwave Users Group Cc: ch...@go-mtc.com Subject: Re: [AFMUG] DWDM/CWDM Magic I remember the first IRU I got quoted.

Re: [AFMUG] DWDM/CWDM Magic
We have seen an extremely wide range of prices for dark fiber leases, it's one of these things where every situation and provider is different. I have been quoted prices over $100/mo per strand-mile and as low as $15/mo/strand-mile. A lot of the value seems to be what they suspect you're going to try to do with the strands. 50 Miles to a datacenter, you're gonna be running NxDWDM 100gig waves, big money.

Re: [AFMUG] DWDM/CWDM Magic
For those of you who have dark fiber access, what kind of costs do you have? I'm thinking more of the cost to access these strands? IRU costs, lease, swaps with other providers, etc? I want some sort of ballpark costs to know what's reasonable when we start looking at this over wavelengths for shorter paths.

Re: [AFMUG] DWDM/CWDM Magic
Mark, we do exactly this on a segment where we have leased 2 strands of dark fiber on a 30mile path. The ends of the run have 8-ch DWDM Muxes and we have two spots along the run where we have an OADM in a splice case to drop out a wavelength. At those points, we set a handhole next to the carrier's handhole, and they looped the 2 strands onto a 12F jumper into our case, so our OADM is in our case, in our handhole. Just be sure your optical margins are planned for any potential add/drop points because each does have some loss.

Re: [AFMUG] DWDM/CWDM Magic
You can also do BiDi CWDM/DWDM if you have the optical budget. This way your two strands become two independent loops. Of note is that you can also run both CWDM and DWDM concurrently.

[AFMUG] DWDM/CWDM Magic
We may have the opportunity to grab 2 strands of dark fiber. These will allow us to build a loop between two points on our network. We have been told we can also break into this fiber within our loop. I'm guessing when we break into this fiber they will just extend the dark fiber into our handhole and we will be responsible to figure out what we do once we cut into that fiber. I'm trying to figure out if there is a way to do this passively so we don't have to depend on having our loop run though a customers location. I was thinking of CWDM. I can setup a CWDM/DWDM at our site and send multiple wave lengths down the fiber. Is there a way for me to break out just one wavelength at a hand hole passively? Let's say I have a North/South run of 2 strands going though a hand hole and I what to break out 1270nm for a customer. Is there away for me in the hand hole, passively, to peel off just 1270nm. Put something like a 1x2 splitter in on N1, N2, S1, S2 and send those 4 fibers into the customer site. Then install a couple of 1270nm optics in a switch to preserve the loop for that one customer. Do the optics do all the magic or are there some type of filters in the DWDM/CWDM modules? -- Thanks, Mark mailto:m...@mailmt.com Myakka Communications www.Myakka.com -- AF mailing list AF@af.afmug.com http://af.afmug.com/mailman/listinfo/af_af.afmug.com
