   Keysight (Agilent) 11980A   Description / Specification:    
Keysight (Agilent) 11980A Lightwave Fiber Optic Interferometer

The Agilent 11980A is a Mach-Zehnder interferometer of fixed delay. Used with an Agilent 71400-series lightwave signal analyzer, it allows ,you to measure chirp and frequency modulation (FM) on DFB lasers. Traditional measurements of laser Iinewidth on single-line lasers can also be made. Together, the interferometer, lightwave signal analyzer, and a gateable RF source permit the display of a true power spectrum of single-frequency lasers. This includes the display of intensity modulation linellidth and componenrs of chirp caused by the intensity modulation. Specifications. Optical Insertion Loss, 1300 nm/1550 nm: <8 dB. Wavelength Range: 1250 to 1600nm. Delay Time: 3.5 us, 25 usec with Option 005. Option 005 replaces the standard 0.76 km of delay with 5.2 km, to measure laser linewidth down to 30 kHz. Connector Interface Options. Option 011: Diamond HMS,lQ Connector. Option 012: FC/PC Connector. Option 013: DIN 47256 Connector. Option 014: ST Connector. Option 015: Biconic Connector.

*This is a Web introductory price for one calibration of the Keysight (Agilent) 11980A. Price does not in most cases include measurement performance data. Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

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.
