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.

Broadband Source (BBS)
A Broadband Source is a spectrally large source that emits a signal which contains a continuous range of frequencies with a broad optical bandwidth (usually 100 nm or more). Sometimes called a white light source, there are two different meanings of this term. Visible white light and a source which does not necessarily emit in the visible spectral region.

Coherence
Coherence is the pattern and or relationships of waves due to phase properties.

Linearity
Linearity is the relative difference between the displayed power ratio, Dx/D0, and the actual (true) power ratio Px/P0 caused by changing the displayed power level from the reference level, D0, to an arbitrary displayed level, Dx.

Power Flatness Over Modulation
When changing the wavelength and modulation frequency, and measuring the differences between actual and displayed power levels (in dB), the power flatness is ± half the span between the maximum and the minimum value of all differences.

Singlemode fiber
Singlemode Fiber has a small core, only about 9 microns, and is used for telephony and CATV with laser sources at 1300 and 1550 nm. It can go very long distances at very high speeds. Both multimode and singlemode fiber have an outside diameter of 125 microns - about 5 thousandths of an inch - just slightly larger than a human hair.
