   Keysight (Agilent) 81689A   Description / Specification:   Spec Sheet 
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.

Bandwidth
Bandwidth is the difference between the upper and lower frequencies in a contiguous set of frequencies within which a fiber optic component, link or network will operate.

Extinction Ratio (ER)
Extinction Ratio is the ratio of two optical power levels, of a digital signal generated by an optical source, (example a laser diode), where P1 is the optical power level generated when the light source is "on," and P0 is the power level generated when the light source is "off." The extinction ratio may be expressed as a fraction, in dB, or as a percentage.

Optical Signal-to-noise Ratio (OSNR)
Optical Signal-to-noise ratio is the ratio between the signal power and the noise power in a given bandwidth. Most commonly a reference bandwidth of 0.1 nm is used. This bandwidth is independent from the modulation format, the frequency and the receiver. For instance a OSNR of 20dB/0.1nm could be given, even the signal of 40 GBit DPSK would not fit in this bandwidth. OSNR is measured with a Optical Spectrum Analyzer. It is generally measured at the wavelength of interest.

Repeatability
Repeatability is the variation in a number of repeated measured quantities when measurement conditions are changed and restored. The value corresponds to half the spread between the minimum and maximum value measured.

Wavelength Repeatability
Wavelength Repeatability is the random uncertainty in reproducing a wavelength after detuning and re-setting the wavelength. The wavelength repeatability is ± half the span between the maximum and the minimum value of all actual values of these wavelengths. Example test condition: uninterrupted TLS output power, constant power level, temperature within operating temperature range, coherence control off, short time span. Note: NOTE The long-term wavelength repeatability can be obtained by taken the wavelength repeatability and wavelength stability into account.
