KEYSIGHT N7744A 4-Ch Optical Multiport Power Meter

The Keysight N7744A optical power meter with four power-sensor channels provides increased throughput and operational efficiency to meet today's challenges in manufacturing. Designed for characterizing optical multiport components, these optical power meters offer industry-leading solutions for device connectivity, high-speed measurement data acquisition and fast data transfer for post-processing. The multiport power meter enables fast measurement solutions for all multiport devices; for example multiplexers, PON splitters, wavelength selective switches (WSS) and ROADMs, as well as compact setups for simultaneous testing of multiple single-port devices. The N7744A power meter uses the unprecedented N7740 fiber connectivity concept, which is a quadruple adapter (quad-adapter) with a snap-on quick-locking mechanism. The device to be tested can be connected to the quad-adapter in a comfortable ergonomic working position, even while the instrument is measuring another device. Then the quad-adapter can quickly be snapped on, to provide repeatably high-precision connections.

Standard Calibration $240.00 *
*This is a Web introductory price for one calibration of the KEYSIGHT N7744A. 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.
