Why Optical Audio Cables Still Matter in 2025
Optical audio cables remain popular for several reasons:
No electrical interference — perfect for setups with multiple devices
Clean, stable digital audio transfer
Supports uncompressed PCM and 5.1 / 7.1 surround formats
Universal compatibility with TVs, soundbars, and consoles
Budget-friendly versus expensive HDMI solutions
While optical cables don’t support advanced formats like Dolby TrueHD, they remain a top choice for everyday home theaters and gaming setups.
How to Choose the Best Optical Audio Cable
Before we look at the recommended pick, here’s what matters most when buying a fiber optic cable:
2.1 Build Quality & Durability
Unlike copper cables, optical cables use thin fibers to transmit light. This makes durability critical.
Look for:
High-quality PVC or braided jackets
Gold-plated connectors
Firm, wiggle-free connections
Dust-protection caps
A well-built cable translates to better longevity and fewer connection issues.
2.2 Signal Stability & Compatibility
Make sure the cable supports all common audio formats:
PCM
Dolby Digital
DTS
DTS-HD High Resolution
LPCM
5.1 or 7.1 surround sound
Most modern TVs, soundbars, game consoles, and receivers still include a Toslink port, making optical cables widely compatible.
2.3 Cable Length & Flexibility
Shorter cables are generally better because they:
Reduce signal loss
Stay neat in tight spaces
Are less likely to bend excessively
For TVs close to soundbars or receivers, 3ft cables are ideal.

Plug the other end into your soundbar or receiver’s Optical In.
