UNISOL Fiber optic patch cables provide high performance fiber assemblies that are fully compatible with standard coupling adapters and comply with reliability standards. The document discusses the main types of fiber optic patch cables - single mode and multi mode - comparing their core sizes, transmission speeds and distances, color coding, and applications. Single mode fiber has a smaller core and is used for longer distance transmissions while multi mode fiber has a larger core and is used for shorter distance connections like within buildings.
