OZ Optics’ BB-100/400/500/700-11 series of compact PC board mountable blocking pigtail style variable attenuators with low backreflection are designed to meet Telcordia standards. These attenuators can be used for 1300 nm and 1550 nm as well as for C, L and S bands, with minimal changes in the insertion loss. Mounting holes provide easy attachment to PC boards and patch panels. The mounting hole patterns and attenuator sizes can be modified to meet customer requirementsThe attenuators consist of two collimating lenses, prealigned for optimum coupling efficiency. A threaded radial screw is used to block the collimated beam between the two lenses. Because the attenuator works by directly blocking the beam, it is polarization insensitive. A seal cap is used to seal the junction against temperature and humidity effects. The attenuator can even withstand immersion in water for extended periods of time. Variable attenuators are offered with single mode, multi mode, or polarization maintaining fibers.
