Product Description:

Pigtail Style Inline Variable Attenuators Miniature Pigtail Style Inline Variable Attenuators OZ Optics offers a complete line of low cost, compact PC board mountable pigtail style variable attenuators with low backreflection. These attenuators are designed to meet Telcordia standards. These attenuators can be used for 1300nm and 1550nm, as well as for C (1520-1570nm), L (1570-1620nm) and S (1470-1520nm) 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 our customer requirements on OEM orders. The attenuators consist of two collimating lenses, prealigned for optimum coupling efficiency. A threaded radial screw is used to block the collimat ed 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. Attenuators are offered with singlemode, multimode, or polarization maintaining fibers.In general, OZ Optics uses polarization maintaining fibers based on the PANDAfiber structure when building polarization maintaining components and patchcords. However OZ Optics can construct devices using other PM fiber structures. We do carry some alternative fiber types in stock, so please contact our sales department for availability. If nec essary, we are willing to use customer supplied fibers to build devices. Neutral density filter versions of attenuators are also available in rectangular and reflector style housings.
