Hosa Technology OPM-320 InfiniBand/fibre optic cable 6.1 m TOSLINK Grey

The Hosa Technology OPM-320 InfiniBand/fibre optic cable 6.1 m TOSLINK Grey is a 6.1-metre optical digital audio cable with TOSLINK connectors on both ends, intended for reliable transmission of digital audio signals between compatible devices. This cable supports standard S/PDIF formats and is compatible with ADAT as well as Dolby Digital and DTS surround formats, enabling lossless optical transmission for home theatre systems, audio interfaces and consumer electronics. The grey outer jacket provides straightforward identification and durable handling in home and studio setups.

Advantages

The cable uses fibre optic transmission to eliminate electrical interference and ground-loop noise, preserving signal integrity over the 6.1 m length. TOSLINK connectors on each end ensure secure, easy plug-and-play connections with devices that have Toslink jacks. The cable’s compatibility with ADAT and common S/PDIF formats including Dolby Digital and DTS makes it suitable for a broad range of digital audio equipment without format conversion. The flexible jacket and standardized connectors simplify routing and installation in both residential and professional environments.

Suitable for

• Connecting TVs, soundbars and home theatre receivers via TOSLINK
• Linking DACs, audio interfaces and digital mixers with Toslink ports
• Transmitting ADAT or S/PDIF signals for multi-channel audio setups
• Replacing existing optical cables in living rooms, studios or AV racks

How to use

Align each TOSLINK connector with the optical input/output on your devices and insert gently until it seats; no tools are required. Ensure the optical ports are free of dust or debris before connection to maintain optimal signal transfer. Select the appropriate digital audio output or input on your source and receiving device (for example, set your TV audio output to optical/S/PDIF) and confirm that the devices are configured to use the connected format such as PCM, Dolby Digital or DTS where applicable.

Usage recommendations

Route the cable to avoid sharp bends and crushing; keep a minimum bend radius consistent with fiber-optic handling to prevent attenuation. When connecting or disconnecting, pull on the connector body rather than the cable itself. For best results in complex AV setups, verify device format settings and cable seating if you experience signal dropouts or format mismatches.
