RCA connector
Patch cords are usually produced in many different colors so as to be easily distinguishable from each other. Types of patch cords include microphone cables, fiber optic spectroscopy cables, headphone extension cables, XLR connector, Tiny Telephone (TT) connector, RCA connector and ¼" TRS phone 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 refer only to short cords used with patch panels.
