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). Connector type: straight (opt. 100, 101, 121, 350), angled (opt. 201, 221). Return loss: >35dB (opt. 100), >45dB (opt. 101,121), >60db (opt.201, 221), 22dB (opt.350). Maximum input power: +23 dBm. Options. Opt 100: Standard performance version. Opt 101: High performance version. Opt 201: High performance, high return loss version. Opt 350: 50/125 µm multimode option.

*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.

Chromatic Dispersion
Chromatic Dispersion is a broadening of the input signal as it travels down the length of the fiber. Chromatic Dispersion results from a variation in propagation delay with wavelength, and is affected by fiber materials and dimensions.

Detector
A Detector is a signal conversion device that converts power from one form to another, such as from optical power to electrical power

Jitter
Jitter in technical terms is the deviation in or displacement of some aspect of the pulses in a high-frequency digital signal. Jitter is the time variation of a periodic signal in electronics and telecommunications, often in relation to a reference clock source. Jitter may be observed in characteristics such as the frequency of successive pulses, the signal amplitude, or phase of periodic signals. Jitter is a significant, and usually undesired, factor in the design of almost all communications links (e.g., USB, PCI-e, SATA, OC-48). In clock recovery applications it is called timing jitter.

Polarization Mode Dispersion (PMD)
Polarization mode dispersion (PMD) is a form of modal dispersion where two different polarizations of light in a waveguide, which normally travel at the same speed, travel at different speeds due to random imperfections and asymmetries, causing random spreading of optical pulses. It is he difference between the maximum and minimum values of loss typically measured in ps/km^1/2.
