Thanks HN folks for all the comments. To clarify a bit, the cables are pulled through PVC conduits under the flooring before being buried in cement. Currently the hypotheses for why the cable disintegrated so quickly is hydrolysis and paint solvents. Singapore is extremely humid but this doesn't explain why the exposed cabling on the other end is still healthy and not crumbly. The second possibility is that I keep th…

I see telecoms make loops all the time both indoors and outside. The loops should be strapped together and strapped down though.

Yeah, leaving hanging loops with a gentle bend radius is very common as long as the loop is secured, and does not cause problems. Maybe something pulled on it though?

What’s the advantage of using fiber optics for home networking over 10Gbe Ethernet?

It's one of those "just because" moments. The idea was to future proof my home infra for a 25G NAS connection. Most ethernet connections tap out at 10G. While theoretically speaking Cat 8 cables can do 40G, hardware support for full 40G Cat 8 NICs is rare. Fibre is very very flexible with its potential bandwidth and SFP28 transceivers are relatively affordable (if you don't do what I did by using SMF. Home networks s…

I'd say the opposite - any fibre in a wall should probably be single-mode fibre (SMF), simply for future proofing. Single mode optics aren't much more expensive and single mode fibre hasn't changed nearly as many times as multi-mode. You can run 25G over the same SMF that once ran 1G - not so with MMF.

If you buy a consumer product labeled "military grade" you are buying snake oil. And not just snake oil, incredibly over priced snake oil.

There are some ratings, like semiconductor temperature ratings, with labels that include "military", (e.g. manufacturers may name their products, from the narrowest to widest operating temperatures, with something like: commercial, industrial, automotive, military) and "military" would indicate a better product.

On the other hand, when a product is designed and manufactured to sell to a military, it's going to be expensive, and that extra cost isn't going to quality or capability, it's going to compliance. You're more than likely paying extra to get something using some old and outdated technology, that includes paperwork to prove that it's only built using the approved old and outdated technology.

You say that the connection would be permanently severed, but if the fibre is run through PVC can’t you pull a new run? Easiest way is to use the existing fibre to pull the new cables through.

Anything with “Marine” in its title, is usually 5X more expensive, but worth it. Nothing sucks more than having the engine crap out, 150Km offshore, because your fuel injection system got corroded.

Hell, anything even close to salt water is apt to get ate. What's funny is you'll see people say they want to retire and get a beach house. No. You. Don't. Blowing sand is hard on stuff, getting in gears and moving parts. But the salt, the salt is like some alien monster that just dissolves things that flat landers would never expect. Get the smallest amount of saltwater flooding in a closet with equipment and things start to corrode away like it's an alien acid world.

Shoes need to be used, or the rubber and/or glue holding the sole on will deteriorate.

There's gotta be more to it than that. I've got a pair of dress shoes I wear maybe thee times a year at most, and I've had them for somewhere between ten and fifteen years, perhaps longer. The soles (rubber because winter) are in perfect condition, and the leather isn't too bad either, though I've not really conditioned it enough and it's starting to show.

Environmental factors can be very picky on what gets attacked and what doesn't.

In one of the oddest losses of a pair of shoes, I had fire ants break into my closet and eat the foam rubber out of one pair of extra lite running shoes. Turned the damned things to swiss cheese. Nothing else was messed with. They didn't want leather or rubber, just whatever those shoes were made of.

They offer to provide you with personalized service and you block them? What do you do when you walk into a high end watch or clothing store? FS provides account managers and they are very useful if you are working on a project as they can guide you and help you.

Is it too much to ask to just be able to buy things without being chased around by someone? I have a Newegg business account (and maybe a few more for other pc stores, I'd have to check), but I literally never have them trying to get me to buy things. /shrug

fs.com sells primarily b2b. Account managers are normal and customary.

Just decline politely. They are not a bad company in that regard.

I have my issues with FS product itself, as it can be spotty sometimes in terms of compatibility and repeatability (e.g. getting the same optics firmware every time over the course of a couple years) but they typically handle exceptions and problems quite well. Via your account manager contact.

Weird reason to hate a company, imo. Would be far different if they continued to spam you with phone calls/e-mails after you declined the request.

Sounds like both parties dodged a bullet.

Something caught my attention as a musician: Coiling cables can leave them with a permanent twist, depending on how you do it. Musicians are taught an "over under" method for avoiding this problem. Otherwise, if a service loop is needed, it can be hung in a figure-eight pattern to avoid the twist.

Basically same with any company with "Patriot" or "Veteran" in the name. It's just a weak pander to people's weak egos. Freedumb, if you will.

I don’t disagree but it’s not hard to understand why people think “military grade” means it’s better. “Military grade” communicates tough/durable/stress tested to a lot of people. Veteran/patriot isn’t an indicator of build quality, even if it is also pandering to a certain sensibility.

For many products it just means it's a small run from a group that may not have a lot of domain experience using materials and methods that will make the end product appear superior to buyers.
