That’s a lot of porn and cat pix.

13 km...

A fair distance.

Tell me about it- i can never grab a hold of those cables- they are just way too fast

The ISPs will throttle that down to almost nothing if given the chance.

Putting more fibers in a cable sounds low-tech.

Perhaps the hard part is reassembling the data stream at the far end because each strand’s going to have a slightly different travel time.

In the old days a 9-track tape drive on the mainframes with each track doing 6250 bits/inch had to buffer each track because the tape would shift slightly and corresponding bits from each stream wouldn’t hit the heads exactly the same time.

My dog cannot bite that fast.

My bird, if agitated, is fast, but not that.

Maybe a COVID-19 germ, if jacked up on VAX might nibble at that rate.

How fast is your pet?

This would make it even easier to monitor and control the population. 99% of the population would gain nothing from this.

At this speed, the key is no longer network, but storage.

Current storage tech cannot write at these speeds, so the network will never see these speeds. The bottleneck will move to the datacenter, not the ISP.

And I thought DWDM was fast.

The problem with fiber optical is that, like Thomas Edison’s Direct Current scheme for electricity, it depends on relay booster stations to maintain integrity over distance. Has that been overcome or is this a different animal?

A friend used to say: “Never underestimate the bandwidth of a station wagon full of 9 track tape”.

How many petakibbles in a petabit?

Sometimes you just want to download Netflix... All of it.

Youtube will announce faster censorship times.

Splicing 38-core fibers must be a challenge.
