Four-Port Tunable Laser System Source
N7714A
Laser Source
The Keysight N7711A and N7714A tunable lasers are single-port and four-port sources, available with C-band or L-band wavelength coverage. The narrow linewidth and offset grid fine-tuning capability make them ideal sources for realistic loading of the latest transmission systems. All models can reach any wavelength point within their specified wavelength range just like all other Keysight tunable lasers. In this mode, code compatibility with existing test setups based on Keysight's range of full-size and compact tunable lasers is a great asset. In system loading applications, it may be preferable to grid-tune the lasers like system transmitters, simply by changing the channel index. The channel grid is adjustable to standard ITU-T grid spacing like 50 GHz, and to arbitrary grids. Likewise, the zero frequency (base channel) of the chosen grid is adjustable. A 12 GHz fine-tuning range allows de-tuning the frequency.

Fibolocator
-
Fibolocator is an innovative device for measuring and characterizing breaks and other backscattering-causing faults in optical fibers. Time-resolved correlation reflectometry is the principle on which the device is based. It analyzes the backscattered light like a pulse OTDR, but unlike such OTDRs, cw laser diodes are used. The requirements for the test signal and the complexity of the system are low, which leads to very low costs for OEM subsystems.
