Staff Development Video: High-speed Fiber Optic Systems


The fiber optic revolution periodically adjusts to address ever-changing market requirements. As fiber optic network speeds race beyond 100 Gigabits, innovative solutions are being developed that not only offer lower latency but greater reliability, flexibility, and scalability. To complete the transition from on-off keying to the latest advanced modulation formats, new products and platforms must incorporate technologies such as coherent transmission and forward error correction. Optical amplifiers and system factors such as optical signal-to-noise ratio in complex DWDM systems are also critical considerations in high-speed networks.

This DVD examines how advanced modulation formats improve spectral efficiency through techniques such as amplitude modulation, amplitude shift keying, and phase shift keying. In addition, the content highlights constellation diagrams, coherent detection in receivers, optical transport networks, super channels, modules, and test equipment. Additional chapters focus on how active and passive devices are integrated into transmission equipment for applications such as DWDM.
