Agilent/N7768A /四通道多模光纖衰減器

Miniature bulk optics for best transfer of modal distribution ,Built-in power monitoring for accurate power setting and stabilizing ,Wavelength range: 800 – 1370 nm ,Attenuation range: 0 to 35 dB ,Relative power monitor uncertainty: ±0.1 dB + 300 pW ,Settling time: typ. 200 ms ,Transition speed: selectable 0.1 to 100 dB/s ,Optical path blocking: typ. >60 dB

Optical attenuator instruments are used to flexibly control optical signal power levels in test setups. A primary application is determining optical receiver sensitivity by measuring the BER vs. input signal power. The N7766A and N7768A provide 2 or 4 attenuator channels respectively for multimode fiber setups and are available with either 50 µm or 62.5 µm fiber ports. The output power is monitored, especially to allow accurate and stable power setting independent of the input power. Convenient offset parameters allow the set power to correspond to the signal after other optical components in the setup path現(xiàn)貨供應(yīng)。
