Have you played with the newest bend insensitive fiber? You can wrap it around a pencil and an otdr shows no or minimal loss. But I think you’re correct about damage from average consumers. They’d destroy the ferrule in no time.
- Aurornis 3y agoThe failure mode with consumers is usually pulling cables against a sharp edge. Even a pencil has a larger radius than the edge of your desk or the corner of your computer case. You can buffer the radius by putting a thick jacket around the fiber, which is about the only thing that works. But fiber still isn’t a free lunch. The longest high speed cables already use fiber internally, but they’re expensive because they need extra optics and transceivers inside. Moving the extra fiber hardware into the laptop and client device would make the cables cheaper but make the hardware more expensive. That’s not a trade off that most people would take as most people don’t actually need long cable runs. The above comment was trying to use Apple premium cables as the reference for being too expensive, but opening Amazon shows plenty of Thunderbolt 4 cables in the $20-$30 range from other vendors. It’s really hard to imagine a scenario where forcing every cable to be a combination of fiber and copper would make things cheaper for us consumers.
- solardev 3y agoDo third party thunderbolt cables suffer the quality issues that usb cables have? (counterfeits, different standards, unclear specs, etc.?)
- DannyBee 3y agoB3/A3 Bend insensitive ginger can handle 5mm bend radius. You can wind it around a pencil with no issue. It does fine on the edge of a desk. 5mm is less than a quarter of an inch. I can send you video of beating the crap out of it against the edge of a desk if you want. I've watched tons of modern fiber and cat6 be abused. My dog dug up and chewed some. 0.5db loss. The copper next to it was a complete loss The fiber always wins. As for pricing. Once you get to 10gbps+ its at best a wash. Transceivers are 10-20 bucks. Cheap rj45 10gbps sfp+ are 2-3x that price. Produce a ton of heat as well. This will only get worse. 25gbps fiber transceivers are now almost as cheap as 10 gbps. Meanwhie, higher speed copper standards are much more expensive and produce even more heat. Higher speed fiber is dropping in price. Higher speed copper is not because nothing drives it anymore.

- orand 3y agoPun intended? Cat 5?
- ChrisMarshallNY 3y ago:) How did you know how they test for these specs?
