Optical Toslink cable Hosa OPM-303, Toslink–Toslink, 0.91 m, grey

The Hosa OPM-303 is a 0.91 m Toslink–Toslink optical audio cable with a grey jacket, intended for digital optical connections between consumer and professional audio equipment. It transmits PCM and other S/PDIF-compatible digital audio formats, including Dolby Digital and DTS surround, without electrical interference. The cable uses large-diameter plastic optical fiber and polished terminations to maintain signal clarity and reduce insertion loss in compact setups such as home audio systems, TVs, soundbars, CD players and DACs.

Advantages

The cable’s large-diameter plastic optical fiber provides strong light transmission for reliable digital audio performance. Polished optical terminations minimize signal loss at the connector interface, while robust construction improves durability in repeated use and tight installations. Its 0.91 m length is suited to short runs where a tidy, low-profile connection is required, and the grey jacket offers a neutral appearance that integrates easily into most AV setups.

Suitable for

• Connecting TVs to soundbars or AV receivers via Toslink ports
• Linking CD players, DACs and digital transports to amplifiers
• Short optical runs in home theaters and compact audio systems
• Applications requiring immunity to electrical interference

How to use

Insert each Toslink connector into the optical input or output on your devices until it seats securely; connectors are keyed to prevent incorrect orientation. Use the cable for short-distance digital audio connections between source devices (for example, CD players, media players or TVs) and receivers, soundbars or DACs. Avoid bending the cable sharply near the connector ends and ensure the optical ports on devices are free of dust to maintain signal quality.

Usage recommendations

For best performance, keep the cable length appropriate to the distance between devices and avoid tight bends that can increase optical attenuation. When connecting devices that support surround formats such as Dolby Digital or DTS, verify device output settings to ensure the optical output is enabled and set to the correct digital format.
