Understanding the Test Criteria of Optical Fiber Transceivers Used in Space

In space, high performance components must be able to deliver reliably in the punishing environment. It is optical transceivers that drive transmissions, converting signals to and from a copper-resident format. Fiber optics communications provide high bandwidth and low latency signaling. Signal transmissions through fiber optic cables (FOCs) provide immunity to EM/RFI interference, crosstalk, and voltage level surges. Fiber optics’ accuracy and reliability exceeds traditional cabling. Covering 1,000 feet requires four pounds of FOC versus 39 pounds of copper wiring, and fiber optics also consume less energy than copper. To convert electrical signals from circuitries with copper output to fiber optics, optical fiber transceivers are usually required.

Taking the Fast Bridge between Neural Networks

Neural networks have been around since the 1950s. The advent of fast, massively parallel processors like the Graphics Processing Unit (GPU) have made neural network applications like object recognition feasible. Neural networks are one means used to create Artificial Intelligence (AI). The latest iPhones now have an AI chip, primarily to offload face recognition tasks.1 Voice translation tasks would also benefit from an AI chip. Google provides voice translation as long as there is access to a cloud. The ability to translate directly from a phone without requiring Internet access to Google engines would be advantageous, and it’s possible that the iPhone is headed in that direction.

Optical Interconnect Design Challenges in Space

Aeronautical applications face many design challenges that are unique to their intended environment. The best practices for optical interconnect design for space applications include the use of radiation-resistant technology to defend against space radiation, the use of components and devices that are designed to operate in harsh environments, and meeting size, weight, and power (SWaP) and long-term reliability requirements. Finally, it is recommended to follow open standards like VPX and to look for solutions that comply with MIL and quality standards.

The Internet of Space and radiation resistant transceivers

The explosion of worldwide communications over the past 25 years has led to the pervasive use of mobile and land communications equipment with an abundance of platforms, applications, and devices all driving the growth of many of the largest businesses in the world. There is no doubt that this trend will continue through the Internet of Things (IoT), and the arrival of the 5G technology along with improvements to the underlying network infrastructure. However, the next, ‘Small Step’ for man in terms of ubiquitous communications will be the ‘Giant Leap’ into the Internet of Space.
