SPDIF is ideal for transmitting high-quality audio signals without converting the signal to analog. SPDIF is utilized in Hi-Fi technology, as well as a plethora of audio-visual peripherals such as media players, speakers, and sound cards. Deployments utilize Coaxial, Optical, and Mini-Optical (Mini-Toslink, MiniPlug or Mini Optical jacks) connectors. The SPDIF interface can be implemented as either coaxial or optical.

Coaxial

This interface uses RCA phono connectors and 75 Ohm coaxial cable.

Optical

This interface uses fiber optic cable and is available with two types of connectors — TosLink and Mini Optical.

TosLink Optical Connector

Mini Optical Connector

Mini-optical connectors are sometimes called Mini-Toslink, MiniPlug or Mini Optical jacks, but they all refer to the same connector, as pictured above. The mini-optical connector is typically used on portable media players and other audio devices. The TosLink connector is commonly used in coordination with DVD and CD players, DAT recorders, and surround sound receivers. You may also be interested in our security portfolio.
