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.

 

Features
– 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
