Is Fiber Optic Networking Technology More Secure Than Copper?

August 19, 2020

Because optical connections transmit data using light, they don’t radiate signals that can be intercepted. Security for traditional copper Ethernet connections can now be significantly enhanced, however, thanks to end-to-end encryption standards.

Copper and fiber optic cables have both been implemented in military and aerospace networks for years

The Effects of Extended Temperatures on Flash Endurance and Data Retention

August 10, 2020

The electrical charge stored in a flash memory cell degrades over time, and will degrade much faster at extended temperatures. This degradation has been modelled to follow the Arrhenius Equation, degrading exponentially as temperature rises.
