Attenuators

OZ Optics offers a broad range of both variable and fixed attenuators having key competitive advantages. All of our attenuators operate over the two standard wavelength bands, the C-Band and the L-Band. This wide wavelength range makes these components ideal for DWDM applications. Our attenuators are wavelength insensitive, which means they operate with minimal changes in attenuation when used in either the C-Band or the L-Band and exhibit low return loss. In addition, all of our attenuators have a wide attenuation range, which means they operate at a wide range of power levels. This is important as increased power levels are being used in newer optical systems.

Variable Power Supply
VS3
-
The VS-3 power supply is a very convenient portable, non-isolated “variable source” from 0 volts to 150 Vac or 0 volts to 150 Vdc and rated for up to 3 amps, thus the name VS-3. It is comprised of an illuminated voltmeter that reads to the first significant digit, AC variable system output voltage, DC variable system output voltage, logic output voltage and one sense (continuity) contact monitoring points. Banana jacks for connection of test leads are spaced at intervals that allow the use of dual banana test plugs if desired. The VS-3 is protected by two levels of overcurrent protection; AC input, and ground fault protection by a GFCI. All circuitry is housed inside a custom designed case made from 16 gauge steel. An Internal fan dissipates heat buildup and exhaust through louvered side vents built into the case. The carrying handle is designed with a “spring return to rest” position and is padded for comfort. The case has been sized for optimum portability and is balanced from the handle during transportation. The case has a powder coated finish that is scratch, chemical and weather resistant. Rubber padded feet support the case when in the upright position and a convenience receptacle is located on the side of the case. A unique feature of the VS-3 is that it contains “Magnet Packs” on the back of the case. These “Magnet Packs” can support the VS-3 and allow it to “hang” from any magnetic metal surface. The VS-3 can be powered by our UPS system, eliminating the need for an extension cord. The ability to magnetically attach the VS-3 near the source of connection and eliminating the need for an extension cord makes the VS-3 a “must have tool” for technicians.

High Voltage Pulse Attenuators
-
Barth High Voltage Pulse Attenuators are matched impedance coaxial attenuators for use primarily in pulsed 50 ohm systems, or where occasional transients would damage ordinary units. The attenuator design closely matches the impedance around each resistor, to that resistor. These attenuators feature an input impedance very close to 50 ohms, with characteristics as good or better than most microwave attenuators. These units are ideal for use in nuclear and high energy experiments. Extensive testing during manufacturing insures very high reliability for single-shot experiments. A voltage coefficient of the resistive film of less than .0001 %/V allows low voltage calibration of most systems.

CAT-5 Video Variable Filters
-
It is often beneficial to use a video driver at the output of a video encoder for power savings, line driving, and additional circuit protection. The video driver is typically configured as an active filter, also known as a reconstruction or anti-imaging filter. The purpose of the reconstruction filter is twofold: it blocks the higher frequency components (above the Nyquist frequency) that were introduced into the video signal as part of the digitization process and provides gain to drive the external 75 Ω cable to the video display.
