MDX-19 Series of optical LED transceivers are for ATM and FDDI data-communication networks and mezzanine card applications. These high-performance transceivers integrate duplex data links that provide bi-directional communication over multimode optical fiber. The 1,300-nm LED is suitable for use in network environments such as ATM OC-3 up to 155 Mbits/sec and FDDI at 125 Mbaud. Compatible with either 50 or 62.5 micron multimode fiber-optic cable, the transceivers are for backbone applications.

Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
