SparkFun Distance Sensor
1.3 Meter, VL53L4CD (Qwiic)
This SparkFun Distance Sensor Breakout utilizes the VL53L4CD next generation ToF (Time of Flight) sensor module to give you the highly accurate measurements at short ranges for its size. The VL53L4CD from STMicroelectronics uses a VCSEL (Vertical Cavity Surface Emitting Laser) to emit an infrared laser to time the reflection to the target. That means that you will be able to measure the distance to an object from 1mm to 1300mm away with millimeter resolution! To make it even easier to get your readings, all communication is enacted exclusively via I2C, utilizing our handy Qwiic system so no soldering is required to connect it to the rest of your system. However, we still have broken out 0.1”-spaced pins in case you prefer to use a breadboard.

Single-Port Tunable Laser System Source
N7711A
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.
