QED Performance Optical Graphite

Polymethyl Methacrylate (PMMA) acrylic glass optical fibre

Very Low Jitter Design

Very Low Loss

The new, award winning 'Performance Graphite' Optical cable utilises the superior PMMA acrylic glass optical fibre previously only available in our 'Reference' range products.

The new optical fibre boasts half the signal attenuation per metre of the previous model, which means 'Performance Graphite comfortably transmits the higher bandwidth signals demanded by today's multi-channel digital audio links.

 The cable features a stepped refractive index core that together with precision cladding techniques minimizes light absorption and modal dispersion of single mode optical signals at the fibre boundary. This reduces the angle of incidence at which total internal reflection occurs so that more rays can propagate along the cable, which in turn makes for decreased jitter and improved audio data transmission.

OVERALL PERFORMANCE

Very Low Jitter

Jitter is the undesired deviation from true periodicity of an assumed periodic signal in electronics and telecommunications, often in relation to a reference clock source. A cable displaying very low jitter has been measured at
typically 50ps.
