3.5mm TOSLINK adapter

This adapter converts the connector on the end of a standard TOSLINK cable to a Minijack optical plug. There are two common types of optical connector, TOSLINK and Minijack. Many smaller devices such as MP3 players, CD players, Minidisk players and some PC sound cards use the Minijack type connector. The Minijack optical connector is 3.5mm in diameter and many devices use a multi-purpose socket which double up as both as headphone socket and also an optical Minijack. Examples of those are the Macbook.
