Keysight (Agilent) 8156A Optical Attenuator Mainframe

The HP 8156A Optical Attenuator can be used in both single- and multimode applications. Each optical attenuator is calibrated over its entire 60 dB range at 1310 and 1550 nm. In addition, wavelength characteristics of the instrument are stored in an EEPROM. This allows an automatic correction to be performed for every wavelength and attenuation setting. The Agilent 8156A enables you to attenuate any optical signal up to 60 dB in precise steps over its entire wavelength range. A resolution of 0.001 dB lets you achieve the exact signal power required for your measurement with a repeatability of better than 0.005 dB. Maximum input power is +23 dBm. The Agilent 8156A is available with three different return loss options ranging from 35 dB to 60 dB. The HP 8156A can be used as calibrated and programmable back reflector to check the increase in bit error rate or noise performance as a function of the back reflection level. During your bit error rate measurements you may want to monitor the power level at the receiver input. Instead of using a separate coupler, the HP 8156A offers a built-in 13 dB coupler as an option. Specifications. Attenuation range is 60 dB with 0.001 dB resolution. Wavelength: 1200 nm to 1650 nm. Fiber type: 9/125 µm SM (opt. 100, 101, 121, 201, 221), 50/125 µm MM (opt. 350).

*This is a Web introductory price for one calibration of the Keysight (Agilent) 8156A. Price does not in most cases include measurement performance data. Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

Coherence Length
Average distance over which superimposed waves lose their phase relationships

Linewidth
Linewidth is the width of a spectral line in terms of wavelength, wave number and frequency.

Power Flatness Versus Wavelength
When changing the wavelength at constant power setting and recording the differences between actual and displayed power levels, the power flatness is ± half the span (in dB) between the maximum and the minimum of the measured power levels.

Spectral Width
Spectral Width is the wavelength interval over which the magnitude of all spectral components is equal to or greater than a specified fraction of the magnitude of the component having the maximum value. In optical communications applications, the usual method of specifying spectral width is the full width at half maximum. This is the same convention used in bandwidth, defined as the frequency range where power drops by less than half (at most -3 dB).

Telecom Bands
Optical fiber communications typically operate in a wavelength region corresponding to one of the following Bands. O Band (original): 1260–1360 nm. E Band (extended): 1360–1460 nm. S Band (short wavelengths): 1460–1530 nm. C Band (conventional): 1530–1565 nm. L Band (long wavelengths): 1565–1625 nm. U Band (ultralong wavelengths): 1625–1675 nm
