opticallink
Opticallink is a term for a communications link that transmits data by light. In practice it usually means a fiber-optic link, where data is encoded onto a light signal and guided through fiber. The concept also covers free-space optical links and photonic integrated implementations.
A typical opticallink includes a transmitter, a transmission medium, and a receiver. The transmitter converts electrical
Optical links frequently employ multiplexing to boost capacity, such as wavelength-division multiplexing (WDM) and advanced modulation
Common applications include long-haul telecommunications, data-center interconnects, metropolitan networks, and high-performance computing environments. Free-space variants are
Advantages include high bandwidth, low electromagnetic interference, and good power efficiency over distance. Challenges include installation
