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.

Coherence Time
Average time for the wave train to lose its phase realtionships

Fiber Bragg Grating (FBG)
A fiber Bragg grating (FBG) is a type of distributed Bragg reflector constructed in a short segment of optical fiber that reflects particular wavelengths of light and transmits all others. This is achieved by adding a periodic variation to the refractive index of the fiber core, which generates a wavelength specific dielectric mirror. A fiber Bragg grating can therefore be used as an inline optical filter to block certain wavelengths, or as a wavelength-specific reflector.

Modulation
Modulation is the process by which the characteristic of one wave (the carrier) is modified by another. Adding information into pulses of light.

Power Linearity
When changing the power level and measuring the differences (in dB) between actual and displayed power levels, the power linearity is ± half the span (in dB) between the maximum and the minimum value of all differences.

Stability
Stability is the extent to which a specified property, characteristic, or parameter of a substance, device, or apparatus, such as a fiber optic transmission system, remains fixed with the passage of time or with varying environmental conditions.
