Product Description:

OZ Optics offers a compact, rugged and low cost digital attenuator with high resolution, high speed, high attenuation range and high power handling (blocking technique only). These attenuators have low insertion loss, low backreflection, low PDL and flat wavelength response. These units can be calibrated for up to 4 wavelengths, for C or L bands. Alternatively the unit can be calibrated for a continuous range. By using interpolation between the calibration wavelengths, the unit is capable of providing accurate attenuation levels over a continuous, broad range of wavelengths. OZ Optics' digital attenuators are ideal for use in bit error rate testing, troubleshooting receivers and other active fiber optic components, power meter linearity checks, simulating long distance fiber transmission and power setting. A computer interface allows users to access or remotely control the unit through a PC. OZ Optics provides digital attenuators that use either singlemode, multimode or Polarization Maintaining (PM) fiber. In general, OZ Optics uses polarization maintaining fibers based on the PANDA fiber 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 necessary, we are willing to use customer supplied fibers to build devices. An optional, built-in rechargeable battery is available for field use, where AC power may not be readily accessible.
