Gigabit Crossover Adapter
The Gigabit Crossover Adapter converts any standard Ethernet
Patch Cable to a crossover cable for 1000 BASE networks and below. Used with a standard Ethernet patch cable, the Gigabit Crossover Adapter can network two computers in a Gigabit network without requiring a hub. This feature is great for creating a personal network in the office, a network at home, or for copying files between two computers.
A patch cable or patch cord (sometimes patchcable or patchcord) is an electrical or optical cable, used to connect ("patch-in") one electronic or optical device to another for signal routing. Devices of different types (ie: a switch connected to a computer, or switch to router) are connected with patch cords. Patch cords are usually produced in many different colours so as to be easily distinguishable, and are relatively short, perhaps no longer than two metres. Types of patch cords include microphone cables, headphone extension cables, XLR connector, RCA connector and 1/4" TRS connector cables (as well as modular ethernet cables), and thicker, hose-like cords (snake cable) used to carry video or amplified signals. However, patch cords typically only refer to those short ones used with patch panels.
