Frontier Dark Fiber
I'm looking for a contact at Frontier that can discuss dark fiber.


My current account exec says they don't offer it, yet prior conversations with him and a previous SE revealed that they very much did (just didn't have availability on the paths I wanted at the time).


Their web site highlights it fairly proudly.




I'm aware that availability varies.


I'm aware that they likely don't want to sell it.

Your rights under the ICA are dead. Since 2002 you were only able to
order it if one end was in a tier 3 wirecenter, and it was killed in
2021 as an orderable product.

There's an 8 year transition for existing unbundled dark fiber (February
28, 2029). Dark fiber loops were dead in 2002 under the TRRO.

Re: Frontier Dark Fiber [ In reply to ]
The ICA was signed in 2003 or 2004 with dark fiber in it.


Ahh, but maybe 2021 killed it.




Well, most of the ones I'm looking at would be interoffice, not so much loops.

Re: Frontier Dark Fiber [ In reply to ]
Unless you are a *significant* sized regional operator in an area that
overlaps with Frontier's ILEC territory is it unlikely in the extreme that
they would want to rent you some dark fiber or issue a quote for it.

Or some kind of very large enterprise customer that Frontier will take
seriously like a Fortune 500 sized manufacturing entity.

Here's the list of CLLI codes where you're no longer able to order dark fiber:




https://www.fcc.gov/clli-code-list




It seems odd as I look through there, finding COs with no competitive fiber and yet, they're on the list.

RE: Frontier Dark Fiber [ In reply to ]
When working with ILECs it is important to differentiate what must be offered via ICAs and what is offered commercially. We for example sell a ton commercially but effectively none through our interconnection agreements anymore.

Re: Frontier Dark Fiber [ In reply to ]
I wouldn't have thought that Frontier was able to offer dark fiber, since air distribution fan out is all GPON, is it not?

If their fanout was active ethernet it might be a different story but...

They have access to/control of a large amount of mid-mile and long-haul
fiber built by/as GTE and Verizon. Additionally, while their resi/soho
distribution is all PON, they do have some excess fiber fairly deep into
their network in most markets and actively offer active-E service on it
for the right price (it can even occasionally be competitive). I
imagine they'd sell dark for the right price as well, though you may not
like that "right" price.

Yeah, FU pricing ain't uncommon.

Thanks for the clarification.

Any regional ILEC spanning at least a few counties in size will have some
amount of inter-CO dark fiber, whether they want to sell it to any 3rd
parties is entirely another question.

Re: Frontier Dark Fiber [ In reply to ]
Yes; There was absolutely some outright fraud here. Fraud, that even
when pointed out exactly to the FCC staffers handling this, was simply
ignored. This fraud claims in the rural parts of mendocino county, where
I have operated for 20 years, claims there is 'competitive fiber' within
500' of some of the CO's I would _die_ to have fiber access in, and
which has never ever been possible. The fscking game playing here is
unbelievable. ATT, how far you have fallen...and taking down America
with you.
