Ciena may well be the most important technology company you’ve never heard of. The innovations that wow us (driverless cars), and those we now take for granted (the ability to mobile-stream your favorite show) are the products of ingenuity from some brilliant and forward-thinking companies. But those companies rely on Ciena, another vanguard of innovation, to create and advance the underlying networks that bring their breakthroughs to our doorsteps. VR, AI, IOT, 5G … literally none of it would be possible without the mind-boggling technology that makes the internet itself work. For more than 25 years, Ciena has been the global leader in networking strategy, and our technology has been part of the critical infrastructure running within the most advanced companies in the world.
