Funny. I would have guessed that a profitable company would garner a higher valuation, especially since they don't need money, yet the company is pushing for IPO now. I wonder why they elected to sell themselves short?

That jumped out at me too. My wild guess is that the older fiber is a 10G system, the new one is 40G. From [1] > Unity cable system consists of eight fiber pairs, has design capacity up to 7.68 Tbps, with each fiber pair operating at 9

I guess that was the correct interpretation and why the IEEE editors allowed it. They did mention that they did not introduce the architecture (which is what it sounded like originally) about midway through the article.
