QED Performance Optical Cable 3m
Optical connections are often treated as an afterthought. The cable clicks into place, the sound comes out the other end, and everyone moves on, fair enough.
But if you're sending digital audio between a TV, streamer, CD player or games console, it's still worth getting the fundamentals right. The quality of the fibre, the precision of the connectors and the way the signal travels through the cable all contribute to how accurately the signal reaches its destination. Performance Optical is designed to remove the guesswork.
Using low-loss optical fibre, precision-polished Toslink connectors and a flexible, durable construction, it's engineered to deliver digital audio cleanly and reliably across modern hi-fi and AV systems. Whether you're connecting a television to an AV receiver, a streamer to your hi-fi or a CD player to a DAC, Performance Optical gives you the confidence that you've got this connection right.
Because "it's just an optical cable" is usually said about five minutes before someone starts blaming everything else.

About the QED QE7757
From our tech experts at CEN
The QED Performance QE7757 is the longest TOSLINK optical cable in the QED Performance range at 3m. It connects a TV, soundbar, DAC or AV receiver over a digital optical link, and suits setups where the devices are not side by side.
Who it suits
Choose 3m when the TV is wall-mounted above a soundbar or cabinet, or when a source sits on one unit and the DAC or receiver on another. For devices on the same stand, the 1.5m QE7754 or 0.75m QE7751 will be tidier.
Our tech experts advise
With a longer optical run, take care with routing: keep bends gentle and never pinch the cable behind a wall-mounted TV or under a cabinet. Remove the dust caps and push the plugs fully home. If the source has coaxial digital instead, the QED Performance coaxial cables do the same job. See our QED collection.
