A LAN flylead, often called a "flylead," is a short networking cable used to connect devices within a Local Area Network (LAN). It typically has connectors compatible with Ethernet, like RJ-45 connectors. Flyleads are used for quick, temporary connections between devices such as computers, routers, or switches in close proximity. They are typically a few centimeters or meters long, providing a convenient solution for brief networking setups.
