Для расчета сетки частот DWDM системы передачи можно использовать соотношение, связывающее длину волны с фазовой скоростью ϑ и частотой f можно из определения.
Длина волны соответствует пространственному периоду волны, то есть расстоянию, которое точка с постоянной фазой «проходит» за интервал времени, равный периоду T колебаний, поэтому

Для электромагнитных волн в вакууме скорость в этой формуле равна скорости света (299 792 458 м/с), и длина волны.

Если значение подставить в герцах, то будет выражена в метрах.
