In a home buildout, running fiber is surprisingly inexpensive and easy to do. There is one area to watch out for - In most US homes drywall is installed with screws that go into studs so if you have large bundles of wire or fiber be careful how the sit relative to the surface of the studs. Often the drywall screws will be off by a bit an miss the stud. If you wire bundle is large enough and it is a 2x4 wall vs a 2x6…

Nail plates. Screws should _never_ be able to hit the wiring. If that's possible, someone failed to install nail plates or Smarshield sleeves. As for the sharp corners, IMHO you should always install a raceway of some sort (everyone just uses smurf tube), then pull the fiber in afterward. It takes real effort to fuck up the bend radius of conduit.

I was not referring to wiring going thru studs, but along studs. Nail plates are very effective for going thru studs, but often wire is ran along the side of a stud. If it is a large bundle and you don't keep it centered on the side of the stud it will be close to the surface right where a screw could miss. Of course putting some kind of shielding or sleeve could work, but that is very uncommon in house building.

Smurf tubes work great, but are not practical in some high density environments, especially a house with steel structure and I-beam joists. I used these for some locations in my house, but not all.

I ran fiber when I built my house a few years ago. I have MANY 12 fiber runs going to my IDF/MDFs, Server room, the gate, the dmarc, etc. I also ran SM fiber to every AP location. Out of 20 miles of pulls about 1 mile was fiber.

Why not copper with PoE to the APs? You still have to get power to AP somehow.

I have both. 2 Cat6As plus a SM fiber to each AP location. The APs need power over POE. I just added in my first AP that was 10g (Ubiquiti XGS), and that uses POE over 10g.

It’s usually 20x the outer diameter of the cable for fiber, a cable with a .3 inch OD has a 6 inch minimum bend radius.

What? This is 100% wrong. This is well standardized. As I posted elsewhere: G.657A1/B1 = 10mm (half an inch) G.657A2/B2 = 7.5mm (a little over a quarter inch) G.657A3/B3 = 2.5mm (less than 1/8th of an inch) The only cable you will find with a 6 inch bend radius is going to be armored interlocking fiber cable or something. You can take 2mm G657.A3 fiber cable, wrap it around a pencil, and it will work 100% fine. Even…

If I am wrong, then explain why this 24-strand plenum rated fiber optic cable has a minimum bend radius of 5.9”: https://leviton.com/content/dam/leviton/network-solutions/pr...

I am running a project where the low voltage contractor is pulling this fiber cable into a conduit my electricians are installing.

I don’t doubt your bend radius claims on the fiber optic cables you listed, but there are far more types of fiber cable than the ones you listed.

From the last quote I got, I could buy almost 10 third-party Fs.com optics for the price of a Cisco OEM optic ($2,500 vs $250). And the FS.com seem to be manufactured more durably. And have a lower failure rate.

Personally I prefer Flexoptix for two reasons. First, they are reprogrammable. They will send you a free programming box with your first order if you agree to a public testimonial on their website. Support are also very responsive if you need new codings they'll try to work with you to find something that works (they can push new codes to your coding box). Second, more recently, they have the option to choose "not ma…

I'll check them out. That would be handy as I'm dealing with a bunch of vendors. Thanks for the head's up!

If you have the choice, always run single-mode. It’s infinitely more scalable than multimode and the price is on-par. Around here, SMF is currently cheaper. SMF optics are single digit dollars more expensive than MMF optics, if you use third-party modules. And you might as well use them because your SP does. In my experience they’re better built and more reliable (longer lasting and lower failure rate. n=1000s of mod…

An addendum here that architectural firms and builders will still often spec out MMF for in-building fiber. You want to tell them "No, use SMF instead".

They will look at you funny and maybe even tell you "that's more expensive" because they haven't looked at price lists in over a decade. But they are wrong on all counts (unless you exist in a really whacky market). The only exception here is that some video, HVAC, etc systems require MMF to stay in warranty. In those cases, run both and use the MMF only for that junk.

I mean, for a mere Benjamin, a disregarded LLC will solve that for you.

And while some people preach hard-wired everything I’d probably increasingly not bother at home. . I’ll have to see how much networking and audio stuff I even do given a kitchen fire with s

Maybe in an apartment. In a house, you want wired backhaul on access points, and wired streaming devices.

I just had luck and have my ISP modem close to my desktop PC and desk so I run cable to desktop, laptop dock, TV and consoles all on the same wall.

So worth it as in apartment everyone and everything is blasting wifi. I see like 20+ SSIDs.

Yeah, we got a new house built 4 years ago and one of the biggest regrets is not enough ethernet outlets (running fibre in the house isn't practical yet) and power outlets in various places. It is really hard to think of all the places you would want them ahead of time unfortunately and as each has a cost you don't want to incur it unnecessarily. But my biggest regrets were: - Only a single ethernet port in the basem…

Why 4 ethernet ports? You can just add switch later if that is the problem. I have this setup behind TV for Apple TV+TV

I notice that non US English-speaking tend to use the term CBD instead of downtown, my assumption is that it is because of the NYC thing you mention

British people would say city centre or town centre. Australians are the ones who say CBD.

In New Zealand we refer to it as the CBD, but you could also say city centre or town centre (or just “town”).

Not sure I have ever heard downtown being used to refer to part of a New Zealand city although I understand its meaning.
