According to your delay requirement, we advise and provide the most appropriate time delay coil. The optical delay depends on the fiber type and length. For example, a 20 km fiber coil will create a fixed delay up to 100 µs.
How to calculate a delay according to a fiber length? To calculate the required fiber length to obtain a specific time delay, use the following formula: L = c Δt / n where c is the speed of light in vacuum, Δt is the desired time delay, and n is the index of refraction of fused silica at the wavelength of interest (use n = 1.4677 at 1310 nm and n = 1.4682 at 1550 nm).
