Keysight (Agilent) 81561A 60 dB Variable Optical Attenuator Module

The Agilent 81561A Variable Optical Attenuator plug-in module is an instrument that attenuates and controls the optical power level of light in single mode optical fibers. As plug-in modules for Agilent’s Lightwave Multichannel platform (8163A/B, 8164A/B, 8166A/B) they allow you to set the attenuation factor and/or power level manually, or remotely via a common computer interface. Their high accuracy combined with their flexibility make them ideal as test and measurement equipment for the modern telecommunication industry. The Agilent 81561A is a small, cost effective attenuator modules with high resolution for single wavelength applications. By entering the operating wavelength, the instrument automatically applies the appropriate corrections. Various calibration features allow the user to set a reference power. Both the attenuation and the power level, relative to the reference power, can then be set and displayed in the user interface. An integrated shutter, which can be used for protection purposes, or to simulate channel drops, is available. Specifications. Wavelength range: 1200-1700 nm. Fiber type: 9/125 µm SMF28. Attenuation range: 0-60 dB. Resolution: 0.001 dB. Repeatability: +/- 0.01 dB. Accuracy (uncertainty): +/-0.1 dB. Settling time: typ. 100 ms. Polarization dependent loss: <0.05 dBpp. Return loss: typ. 60 dB. Maximum input power: +22 dBm. Shutter isolation: typ. 100 dB. Connectivity: straight connector

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.
