The Gembird CC-OPT-7.5M is a 7.5 meter long, 5mm diameter black cable with Toslink plugs affixed to both ends. This cable is used to transfer digital audio signals, primarily from audio devices such as DVD players, CD players, satellite boxes, and video game consoles to an amplifier with optical input. As the connector used is a Toslink, the cable is typically used for fiber optical cables, providing better signal integrity over shorter distances. This cable can be used to transmit mono or stereo audio, and supports other digital audio signals, such as Dolby Digital and Non-HBR (High Bit Rate) audio. The plugs are made from plastic, providing a good grip and easily connected.
