Optical data connections are used mostly in long-haul communications and in large server farms. Due to their ability to transfer massive amounts of data at the fastest rate possible, these connections make up the backbone of communications infrastructure. Most of the interconnect technologies use electrical signals sent along copper wire to transfer data between the high-speed fiber optic connections and the users. Copper is also used inside computers as a core interconnect technology. However, copper has reached its peak performance and the only solution to transfer higher volumes of data using electrical signals is to have more connections. This limitation of copper poses a major threat to the future of microprocessor manufacturers.

In plain terms, mining operations pertain to the set of activities that facilitate the exploration, production, and separation of certain desirable metals and minerals from their ores. With all the major day-to-day operations based on the availability of these minerals, the importance of the mining industry increases manifolds. Mining operations are dependent on several factors that pertain to the accurate estimation regarding the positioning and recovery of the reserves. Some of the key factors that help aid the decision relating to the type of the mining operations includes.

An LMS is a software application used to plan, deliver, and manage online courses. It uses web-based technology to manage, administer, track, and evaluate the performance of participants. LMS is widely adopted by corporations and educational institutions, especially in the higher education sector. The substantial cost benefits and increased employee efficiency and productivity have prompted leading companies worldwide to replace traditional forms of learning with LMS. Additionally, organizations operating global-scale businesses prefer LMS, as it enables them to train employees irrespective of their geographical location.

Manufacturing companies need PLM software because it deals with different functional levels of an organization such as product designing, design engineering, and manufacturing. The need for managing a product during the manufacturing process has led to the development of PLM software and services. The growing complexity of products and the increase in product portfolio across organizations has led to the demand for a system that can provide solutions to the production process across industries. The implementation of PLM in an organization provides higher revenue, reduces cost, and increases capital efficiency.

An ePedigree is an electronic record that takes care of the pedigree requirements of a drug. A pedigree contains information regarding the various levels of transactions resulting from a change of drug ownership from manufacturers to wholesalers to retailers. The record includes different important information such as the date of the transaction and the details (names and addresses) of all parties such as manufacturers, wholesalers, and retailers involved in the transaction.

The inertial measurement unit (IMU), which is typically used in an automotive application, is an electronic device to measure and report a vehicle's specific force (the non-gravitational force per unit mass), angular velocity, and the changes in the magnetic field surrounding the vehicle (or specific parts of the vehicle). An IMU usually refers to a fusion sensor unit (a combo sensor), which is basically a box containing three accelerometers and three gyroscopes. The accelerometers are typically oriented in such a manner that their axes are orthogonal to each other.

GaAs, which is also known as a compound III-V semiconductor, is used in devices such as infrared LED, monolithic microwave ICs (MMICs), microwave frequency ICs, solar cells, optical windows, and laser diodes. It is increasingly used as a replacement for silicon wafers due to its electronic properties. GaAs has high saturated electron velocity and electron mobility, which allow GaAs devices to function efficiently at frequencies above 250 GHz. Due to the wider band gap, GaAs wafers are less sensitive to heat and emit less noise, especially at higher frequencies, compared to silicon wafers. Due to these properties, they are used in mobile devices, wireless communications, aerospace and defense, and automotive systems.
