Keysight (Agilent) 81689A 1525 to 1575 nm Compact Tunable Laser Module

The Agilent 81689A Compact Tunable Laser Source Module for use with Agilent 8163A/B Lightwave Multimeter, Agilent 8164A/B Lightwave Measurement System, and Agilent 8166A/B Lightwave Multichannel System. The Agilent 81689A allows a realistic multi-channel Lest bed for DWDM transmission systems to be set up. Its continuous, mode-hop free tuning makes it quick and easy to set even the most complex configurations to the target wavelengths and power levels, jusL by dialing or using the vernier keys. The Agilent 81689A is available wi th both standard single-mode fiber and Panda-type PMF. Specifications. Wavelength Range: 1525 nm to 1575 nm. Wavelength resolution: 0.01 nm, 1.25 GHz at 1550 nm. Tuning speed (typical): < 10 sec / 50 nm. Absolute wavelength accuracy: ± 0.3 nm. Relative wavelength accuracy: ± 0.3 nm. Wavelength repeatability: ± 0.05 nm. Wavelength stability: ± 0.02 nm (typ. 24 hrs at constant temperature). Output power (continuous power on during tuning): = 6 dBm (1525 - 1575 nm). Minimum output power: -3 dBm. Options. Option 021, Single Mode Fiber, straight contact connector. Option 022, Single Mode Fiber, angled contact connector. Option 071, Polarization Maintaining Fiber, straight contact connector. Option 072, Polarization Maintaining Fiber, angled contact connector.

Amplified Spontaneous Emission Source (ASE)
ASE, a process where spontaneously emitted radiation (luminescence) is amplified. In lasers and particularly in high-gain erbium-doped amplifiers, amplified spontaneous emission is usually an unwanted effect. It tends to limit the gain achievable in a single stage of a fiber optic amplifier to the order of 40–50 dB.

Dynamic Range
In a transmission system, the ratio of the overload level to the noise level of the system, usually expressed in dB. Ratio of the highest to lowest detectable signal of a system, expressed in dB.

Optical Power
Optical Power is usually measured in "dBm", or decibels referenced to one miliwatt of power. while loss is a relative reading, optical power is an absolute measurement, referenced to standards. You measure absolute power to test transmitters or receivers and relative power to test loss.

Relative Wavelength Accuracy
When randomly changing the wavelength and measuring the differences between the actual and displayed wavelengths, the relative wavelength accuracy is ± half the span between the maximum and the minimum value of all differences.

Wavelength is a term for the color of light, usually expressed in nanometers (nm) or microns (m). In Fiber Optics the wavelenghts mostly used are in the infrared region where the light is invisible to the human eye.
