OZ Optics’ (R)ND-11 series of expanded beam style neutral density fixed attenuators are ideal for multi mode applications and for applications where attenuating fibers are not available or usable. These pigtail-style attenuators provide mode independent fixed attenuation when used with multi mode fibers. The insertion loss will not depend on how the light is launched into the fiber. This is a significant advantage over other attenuator designs.
The attenuators consist of a set of collimating and focusing optics and a central baseplate containing the filter. The expanded beam design permits higher power handling than plug style attenuators. The filters themselves can be either permanent (ND-11 series) or removable (RND-11 series). This provides great flexibility for experimentation.
