Key Concepts
Brief History of Optical Fiber Technology
Multimode and Single-mode Fiber
Basic Fiber Optic Link Concepts and Applications to the Computer Industry
Challenges: Connectivity and Interoperability
Newer technologies involving higher datarates, smaller form factors, higher port densities, pluggability, and parallel links are showing an increased need to focus on connectivity and interoperability issues
Conclusions
Historically, the fundamental concepts of fiber optics date back to 1927
Multimode fibers use a core diameter of either 50 or 62.5 microns
Short wavelength lasers
Shorter distances (few hundred meters)
Single-mode fibers use a core diameter of 9-10 microns
Long wavelength lasers
Longer distances (several kilometers)
A basic link is composed of optical transceivers, cables, and connectors
Fiber optics is widely used for both voice and data communication, and is gradually becoming a more fundamental part of future computer architectures
