Rack Type Optical Delay Line Unit

Manual type optical delay lines enable highly precise and stable adjustment of the amount of delay by tuning optical path length. This product combines the delay lines as units. A 3U rack can contain up to 8 units.
Since every optical path is designed to be tunable in space, it is very unlikely to be affected by polarization or dispersion.

- Low loss; low loss fluctuation; and high return loss
- High resolution and a large amount of delay - All units are compatable with the Polarization Controller and Wavelength Tunable
Filter modules and can be arbitrarily combined within a rack
