I'm getting google fiber installed at my house and the guy said he can just reuse att's fiber line
Is that a good or bad idea?

the backbone is probably oversubscribed 1000x already anyways. you don't have a choice but 99% of the time you won't notice.

>>106206341
Well now the cable looks like this, what the fuck did he do?
Aren't fiber wires extremely fragile?

>>106207166
those are powerlines, dumbass

>>106207520
That's where the fiber line was coming through before, what else could it be?

>>106207166
I'd be a bit concerned about how tight that fiber seems to be pulled, but as long as there aren't any severe bends it should be fine, if you want to address it yourself you can actually get a coupler and a short patch cable so long as its SC/APC on both end (AT&T uses SC/APC so it should be this, avoid anything UPC)

>>106207969
I can wiggle it back and forth with my finger, it's not that tight
it's just that previously it was a fully sheathed cable, why the hell did he do that? What did he even do to make the cable like that?

>>106208008
There really isn't any reason at all to remove the jacket unless the installer spliced it, I've never seen one do that and leave a non-jacketed fiber strand exposed.

>>106204816 (OP)
it's got at&t cooties

>>106208075
Did I already fuck it up by touching it with my finger
I sent an email to google saying this shit is ghetto and they need to fix it

>>106204816 (OP)
Fiber degrades over time so I'd be happy they don't reuse old fiber.

>>106208138
well uh, he already did it
he told me there wouldn't be any problems doing that...

>>106208121
Nah, as long as its intact and has no major bends its fine for now. Google is notorious at least in my area for shit installs, once installed (correctly) it works pretty well typically. The only truly sensitive bits you need to worry about are the ends, which should be plugged in anyways.

>>106204816 (OP)
>and the guy said he can just reuse att's fiber line
What do you think? It's worn out? There's new fiber that has more bandwidth?

Unless it's kinked (which results in like 99% packet loss so you'd immediately know) it's fine.

>>106208148
What about reusing the old fiber line from AT&T in the first place, would that cause problems?

>>106208163
I don't know, I don't know shit about fiber other than it's light

>>106208138
>Fiber degrades over time so I'd be happy they don't reuse old fiber.
wtf? No it doesn't.

>>106208169
>would that cause problems?
fiber generally either works or it doesn't. It's not like copper where you can smoosh it a little/compromise the insulation etc and just get a little bit of noise so the ends switch to a slower mode. If fiber gets messed up you get maybe a few ARP packets through, you'll immediately know and it just won't work.

>>106208189
Have there not been any changes to fiber cables in the past several years or anything to make them better?

>>106208197
>Have there not been any changes to fiber cables in the past several years or anything to make them better?
No there haven't. It's the same glass with holographic ridges its always been. If you want more bandwidth you make changes to the terminals.

Even if there were Google wouldn't give you the priority on their router to take advantage of it anyway.

>>106208169
So long as it was tested good and works with the equipment, there shouldn't be any issues re-using AT&Ts single mode fiber, as another poster pointed out, fiber either works or it doesn't, and if you have a connection with no packet loss, it works

>>106208197
Multi mode fiber has had multiple revisions over the years to handle greater bandwidth, but every fiber ISP I've seen uses single mode fiber which is pretty futureproof as far as a cable type can be. Research single mode vs multi mode if you're curious.

>>106208220
I mean it all works, it just seems kind of nigger rigged and I have no idea why he unsheathed the cable and just left it exposed in the hall like that

>>106208226
Yeah that part is questionable and I'd be pissed if I saw something installed that way for anything I manage

>>106208239
For what reason would you even unsheathe the cable?

>>106208271
Only things that would come to mind is to either splice it or to make it easier to shove it somewhere

>>106208326
Why would you have to splice it
It just came out of the floor straight into the att ONT before
I wish I had looked at it before he left but I don't know how he would have unfucked it without running a whole new wire which he obviously wanted to avoid

>>106207166
why is there brown shit all over your wall

>>106208340
Did he by chance put a new connector on the end? If the previous one was damaged that could have been a reason

>>106208366
I don't know, I didn't watch whatever he was doing

>>106208346
they installed it behind the toilet for convenient shitposting

>>106208144
He lied. You got fucked and they saved some money. Remember to never fully trust people because there are many scumbags in this world.

Fibres are all the same it is the stuff on the other end that makes the difference (CBT boxes, OLT connections, backhaul).

>>106210371
>CBT box
?

>>106210592
Connectorised Block Terminal, where fibres from different houses in a neighbourhood get plugged into.

>>106210615
Is changing where those are plugged in the only way to get a new IP when you're on fiber?

>>106204816 (OP)
ask for a new line
so you get your own dark fiber from old att

>>106211339
do this and sign up to be a transit ASN lel

>>106211297
It would still go to the ISPs DHCP pool, your ONT's MAC address would get the same ip usually. I don't know the internals of PON networking, but CGNAT is a common restriction on newer ISPs due to IPv4 "land grabs".

>>106212307
I just remember on AT&T fiber it said it was DHCP but I had the same IP address ever since I signed up for their service, which caused a lot of headaches when I didn't want a static IP and I could never figure out how to change it or why it behaved that way

>>106210615
You mean an OLT?

Optical Line Terminal.


Customer equipment is the ONT/ONU

Optical Network Terminal / Optical Network Unit.
