Read that as "fires first photos", and naturally wondered whether they were cat photos... where is the coffee...
Trans-Pacific FASTER fibre fires first photons, finally
Backed by Google and built by NEC, the FASTER consortium submarine cable has been lit up. The 9,000 km trans-Pacific cable connects two locations in Japan – the Chiba and Mie prefectures – to US hubs covering Los Angeles, San Francisco Bay Area, Portland and Seattle. As well as The Chocolate Factory, the 60 Tbps design …

The internet is a series of tubes, and those tubes are full of cat-shaped photons.

Re: was wondering why it wasn't landing in Hawaii
"then saw the map of the cable - it brushes the Aleutian Islands to get the shortest fastest route."
Yes, it'd be nice if the so-called "hero" image was something useful instead a random "fibre lamp" type image. Is the image editor on holiday again? I'd like that job. Not too much work and lots of holidays.

Re: Google takes 10 Tbps for cloudy ad-slinging
From the linked article:
"Google's one of six members of the FASTER Consortium, with sole access to a pair of 100Gb/s x 100 wavelengths optical transmission strands between Oregon and Japan — one strand for sending and one for receiving."
So 10Tbps full duplex then.

Re: So any of you brainiacs
The article gives a distance of about 9000km. Speed in optic fibre varies slightly depending on wavelength & type of fibre, but is around 204m/uS. So I calculate a bit would take about 44mS to travel from end to end.
If the speed is 100Gb/s, that means that there will be about 4.4G bits in transit along the cable - the cable itself will be "storing" 550MB of data!

And that's only Googles 1/6th share of the total capacity, there could be up to 6TB in transit at any one instant.. Maybe next time they could use mercury and "store" even more data in it and save on data centre capacity, power and cooling all at once.
On a slightly serious note, I wonder how much total "storage capacity" the worlds networks have in transit.

Re: So any of you brainiacs
... and at 200 m/us, each bit is 2 mm long for 100 Gbps. As implmented, they actually send 4 bits/Hz on a 50 MHz lambda using a scheme called DPQPSK, and then use a 0.5 FEC scheme to encode e.g. 100 bits into a 200-bit FEC block, for a speed of 100 Gpbs of data bits.
