The price for two modems and the cable is just under $120

I think this is more a usecase for places where you already have a copper cable available (eg. telephone cable between buildings). If you have to dig and pull a new cable, doing fiber is the only logical choice now, but the price for all that is way way above $120.

You can also buy 50km on that page! But the fiber is raw (unprotected) so I would think that its not usable to run outdoors?

1KM of fiber cable for $60 seems crazy cheap when you contrast it with 3D printer filement. More so as I'd of thought the former be more expensive to manufacture.

  Fiber is generally laid just once. But the filament is a recurring cost to consumers so it provides more value to businesses ... and therefore more opportunity for a higher demand and higher price.

    Does seem very much that the whole 3D filement market just needs one disruptive supplier. Which often happens when you have high-margin consumables markets. Which with the ink printer market saw makes of the printers introduce DRM into the consumables - something I don't see happing with 3D filement though, so could be interesting. That all said, I see that there are products that can convert your plastic bottles into 3D printer filement - https://3devo.wpmudev.host/filament-makers/ https://3devo.wpmudev.host/filament-makers/

  There aren't that many types of fiber optic cable, the actual cable diameter is extremely small (single mode might have 9µm core), and the product is used in large quantities by price-sensitive, sophisticated consumers doing large-scale capital investments. Ethernet cable is also very cheap. 3D filament is a consumable, like paper!

You linked unterminated single-mode fiber and a dual-fiber multi-mode media converter, you can't actually use these together. You need something more like this: - Terminated single-mode fiber: https://www.fs.com/products/74355.html?attribute=255&id=302947 https://www.fs.com/products/74355.html?attribute=255&id=3029... - 2x SFP transceivers: https://www.fs.com/products/75335.html https://www.fs.com/products/75335.html - 2x media converters (or NICs): https://www.fs.com/products/96396.html https://www.fs.com/products/96396.html The price is over $200.

  If you look closely in the parent’s fiber product photo (last picture), the seller providing the connector for free.

  Wouldn't cost of burying that cable be like 50x of that anyway?
  - sethhochberg 4y ago
    These solutions for things like IP-over-copper-pair are typically designed for situations where you already have the cable buried or strung on poles or whatever - so the choice isn't whether to lay new copper or lay new fiber at roughly equal expense, its really whether to use the existing copper or lay the new fiber at much greater expense

      Thank you, this wasn’t clicking for me until I read this. Of course there are countless places with a dead phone line hanging between them.

        Or a fat old conduit that you can run a new wire through...
yosheli123 4y ago
Yeah, I think there's other considerations like power, overall size, input voltage supply, ease of maintenance etc. If it's purely down to cost then I don't these modules would compete

Nitpick, I don't think you're going to just run bare fiber outdoors, not even indoors. You would need to first run your own ducting/conduit and then have the equipment to pressure force the raw line through the shielding. So, much more expensive. But you can get outdoor rated cable with moisture absorbing gel for not too much I believe (struggling to find a price). Some even come with wire-mesh already attached in the event you have to hang it between elevated positions (like telephone poles). But you would need all of that for a copper run outdoors as well so it doesn't change your point. Back to your point, fiber came to my mind as well. Why bother running CAT5/6 when you can just run fiber? Maybe its meant for existing infrastructure? But if that's the case, what was utilizing that infra before? Is it just in cases where you happen to have phone lines running between buildings?

  what does 'pressure force the raw line through the shielding' means ?
  - LargoLasskhyfv 4y ago
    Blowing the fibre or cable with compressed air through the empty 'speed pipes'. As in one end of the fibre is connected to some sort of plug, while the rest is on a spool, the plug is then inserted into a narrow pipe, and pushed through it by pressure.

A 1km reel of unsheathed 9/125um single fiber strand would last maybe about one minute during installation before it snapped.
