   KEYSIGHT N7714A   Description / Specification:    
KEYSIGHT N7714A 1527-1565 / 1570-1608 nm 4-Port Tunable Laser Source

The Keysight N7714A Tunable Laser Source is a four-port source, available with C-band or L-band wavelength coverage. With high output power up to +15 dBm, narrow linewidth of 100 kHz, gridless and grid-defined wavelength setting, and offset fine-tuning capability, the N7714A makes an ideal source for realistic loading of the latest transmission systems. Targeted for high test throughput, lowest cost-per-channel, and narrow footprint, all members of Agilent’s 77-Series optical test instruments are built on a common platform and a common PC-based user interface. A complete set of control interfaces including LAN, USB2.0 and GPIB simplifies integration with manufacturing control systems. Code compatible to Keysight’s Lightwave Measurement System modules, the new instrument generation can serve as plug-in replacements in existing test solutions.

Bit Error Ratio (BER)
Bit Error Ratio (BER) is the ratio of errors caused by the number of bits in a data stream that have been altered due to noise, interference, distoriton or bit synchronization errors.

Variation of insertion loss on the passband of an optical device.

Polarization Dependent Loss (PDL)
Polarization Dependent Loss is the difference between the maximum and minimum values of loss due to the variation of the polarization states of light propagating through a device. PDL is expressed in decibels. Calculated by; PDL = 10 log10 (Ep/Es), where EP and ES are the measured diffraction efficiencies for P- and S-plane polarized incident light, respectively.

Return Loss (RL)
Return Loss (RL) is the ratio of the incident power to the reflected power expressed in dB. RL = 10log (Pin/Pback)

Wavelength Resolution
Wavelength Resolution is the smallest possible displayed wavelength increment/decrement.
