About the QED Performance Optical Graphite
The Performance Optical Graphite connects DACs, TVs, CD players, Blu-ray™ players, and games consoles to AV amplifiers, receivers, and DACs via Toslink. It uses a polymethyl methacrylate (PMMA) acrylic glass optical fibre to handle the higher bandwidth signals required by multi-channel digital audio links. The cable is optimised for a very low jitter design to reduce digital errors and deliver cleaner audio data transmission.
Features and benefits
Polymethyl Methacrylate (PMMA) acrylic glass optical fibre
The PMMA fibre offers half the signal attenuation per metre of the previous Performance model, making it well suited to higher bandwidth multi-channel audio signals. For HD multi-channel audio applications over 12MHz, see the QED Reference Optical Quartz cable.
Very low jitter design
QED identifies jitter — distortions caused by errors in light transmission — as a key factor in audio signal degradation. Precision cladding techniques reduce jitter, resulting in a cleaner signal with better dynamics and a wider soundstage.

About the QED QE6603
From our tech experts at CEN
The QED Performance QE6603 is a 3m Toslink digital optical audio cable from QED's Performance Graphite range. It uses a PMMA acrylic glass optical fibre with fluorinated polymer cladding, 24K gold plated Toslink connectors, and a very low jitter design to reduce errors in light transmission. Attenuation is 0.15dB/m at 650nm.
Who it suits
This cable suits anyone connecting a TV, CD player, Blu-ray player, games console, or DAC to an AV amplifier or receiver where a longer cable run is needed. The 3m length works well when equipment sits apart in a media unit. For a shorter run, the QE6601 in 1.5m is the alternative.
Our tech experts advise
Do not bend the cable tighter than its 9mm minimum bend radius. The PMMA fibre handles multi-channel digital audio well; for HD audio above 12MHz bandwidth, QED's Reference Optical Quartz range is the step up. This cable includes a two-year warranty; browse the QED range at CEN.

Frequently Asked Questions
Q: What can I connect with the QED QE6603 optical cable?
A: It connects the Toslink optical output of a TV, CD player, Blu-ray player or games console to the optical input of an AV amplifier, receiver or DAC.
Q: Is the QED Performance Optical Graphite suitable for HD multi-channel audio?
A: It comfortably transmits the higher bandwidth signals used for multi-channel digital audio. For HD multi-channel audio applications over 12MHz, QED recommends its Reference Optical Quartz cable.
Q: How tightly can the QED Performance Optical Graphite be bent?
A: The minimum bend radius is 9 mm. Avoid bending the cable more tightly than this.
