Optical Toslink Cable UGREEN 70892 — 2 m, black

UGREEN Toslink optical cable model 70892 is a 2-meter black digital audio cable with Toslink connectors designed to transmit PCM and multichannel digital audio between consumer electronics. The cable uses fiber optic transmission to reduce electrical interference and maintain signal integrity across common home AV distances. Its slim, black jacket and standard Toslink plugs enable simple plug-and-play connections between TVs, soundbars, AV receivers, DACs and gaming consoles without external power.

Advantages

The optical design eliminates ground loops and is immune to electromagnetic interference, providing stable digital audio delivery in environments with multiple electronic devices. Its 2 m length covers typical living-room layouts while keeping cables manageable and discreet. Standardized Toslink connectors ensure broad compatibility with devices that support optical audio output or input. The cable requires no drivers or configuration and operates transparently with PCM and multichannel formats supported by connected equipment.

Suitable for

• Connecting a TV to a soundbar for digital audio output
• Linking an AV receiver to source devices for multichannel audio
• Connecting a DAC or external decoder to a digital audio source
• Wiring gaming consoles to home audio systems

Key specifications

• Length: 2 m
• Connector type: Toslink (optical)
• Conductor: optical fiber for light-based signal transmission
• Jacket color and finish: black, slim profile
• Supported audio formats: PCM and multichannel digital audio (subject to device support)
• Installation: plug-and-play, no power required

How to use

To use the optical Toslink cable, align the square Toslink plug with the optical port on the source device and the receiving device, then insert gently until it seats. Ensure both connected devices are set to use the optical audio input or output in their audio settings if needed. Avoid bending the cable sharply; maintain gentle curves to preserve the optical fiber. If audio is not present, verify that the source is outputting digital audio and that the receiving device is set to the correct input.

Usage recommendations

For best performance, route the cable away from heavy electrical wiring and power supplies. Keep bend radius moderate and avoid crushing or tightly coiling the cable to prevent microbends in the fiber. When connecting devices, select compatible audio formats in device settings and confirm sample rate/bit depth compatibility if using external DACs or professional audio equipment.
