   Keysight (Agilent) 81640A   Description / Specification:    
Keysight (Agilent) 81640A 1510 to 1640 nm Tunable Laser Module

The Agilent 81640A Tunable Laser module (back-loadable) fit into the Agilent 8164A, 8164B Lightwave Measurement System and the Agilent 8166A, 8166B Lightwave Multichannel System. Have a built-in wavelength control loop. As it is made mode-hop free tunable with continuous output power, it qualifies to test the most critical DWDM components. The Agilent 81640A module is ideally constructed to characterize integrated optical devices. It's Panda PMF output ports provide a well-defined state of polarization to ensure constant measurement conditions on waveguide devices. A PMF cable easily connects an external optical modulator. The Agilent 81640A tunable laser module is equipped with two optical outputs. One output port delivers a signal with ultra-low source spontaneous emission (SSE). It enables accurate crosstalk measurement of DWDM system components with many channels at narrow spacing. A power meter module alone is sufficient to characterize steep notch filters, such as Fiber Bragg Gratings. The second output port provides increased optical power and allows adjustment by more than 60 dB through a built-in optical attenuator. Specifications. Wavelength Range: 1510 nm to 1640 nm. Wavelength resolution: 0.1 pm, 12.5 MHz at 1550 nm. Tuning Speed: 400 ms/600 ms/2.8 s (typ. For a 1/10/100 nm step). Absolute wavelength accuracy: ±15 pm. Relative wavelength accuracy: ±7 pm, typ. ±3 pm. Wavelength repeatability: ±1 pm, typ. ±0.5 pm. Wavelength stability: <= ±1 pm (typ. 24 hrs at constant temp.). Output 1 low source spontaneous emission (SSE): Max Power: >= -5 dBm peak typical; Min. Power: -13 dBm. Output 2 Max. Power: >= +4 dBm peak typical; Min. Power: -5 dBm (-60 dBm in attenuation mode). Option 071: Polarization Maintaining Fiber, straight contact connector. Option 072: Polarization Maintaining Fiber, angled contact connector.

dBm
Optical power referenced to 1 millimatt

Multimode Fiber
Multimode Fiber has a large core (almost always 62.5 microns - a micron is one one millionth of a meter - but sometimes 50 microns) and is used with LED sources at wavelengths of 850 and 1300 nm for short distance, lower speed networks like LANs. 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.

Power Repeatability
Power Repeatability is the random uncertainty in reproducing the power level after changing and re-setting the power level. The power repeatability is ± half the span (in dB) between the highest and lowest actual power. Note: - The long-term power repeatability can be obtained by taken the power repeatability and power stability into account.

Refractive Index
The refractive index or index of refraction of a substance is a measure of the speed of light in that substance. It is expressed as a ratio of the speed of light in vacuum relative to that in the considered medium. The velocity at which light travels in vacuum is a physical constant, and the fastest speed at which energy or information can be transferred. However, light travels slower through any given material, or medium, that is not vacuum.

Total insertion loss
A measure of the loss of light within an optical component
