Description
ν(λ)=c/n(λ)
ここでcは真空中の光の速度(299,792,458メートル/秒)である。
DMDシフト=(19μmでのピーク遅延)−(5μmでのピーク遅延)
1.黒色のファイバーは4831MHz・kmのEMBと測定され、それゆえOM4として認定される。しかしながら、EMBがほんの僅か4700MHz・kmより高いため、正のDMDシフトがBER性能を低下させ、ファイバーはシステムレベル試験に不合格となる。単一の赤で塗ったデータ点はイーサーネット・トラフィック・アナライザーを用いて得られた、またシステム不具合を実証する。
2.緑色のファイバーは4286MHz・kmのEMBを有し、その結果OM3として分類される。しかし、大きな負のDMDシフトを示すので、ファイバーはBERシステム試験に合格する。
3.赤色及びバラ色のファイバーは共にOM4で同様のEMB値を有するが、赤色のファイバーは正のDMDシフトを有するのに対して、バラ色のファイバーは負のDMDシフトを有する。その結果、赤色のファイバーはBERシステム試験に不合格の一方、バラ色のファイバーは合格する。
