   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.

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
