Erbium Doped Fiber Amplifier
S-102
The EDFA slot module of FOTS system with built-in power booster EDFA module offers a special function that is able to change the optical signal amplification feature variously, which is followed by user’s driving embedded pump LD freely. The output power of eash pump LD can be controlled separately by the program that is set up by user. When an optimum optical signal amplification particularity is needed, it is made up so that it can be materialized by choosing the Default mode provided along with User mode. More stable application of EDFA is possible through the monitoring of the factors such as in/out signal power, gain, alarm status and pump LD enabled by the application of FPGA processor which makes high speed driving possible. It is also set up that user’s present-time monitoring and control through LCD monitor of system main frame or GUI display for remote control can be possible. Through optimization of amplifier gain, noise figure, and saturated output power, this EDFA module will expand test capabilities in systems, components or sub-assembly manufacturing.

RF Test Spectrum Measurements over CPRI
Integris 3000
Most modern cell tower network configurations place the Remote Radio Head (RRH) at the top of the tower and the baseband unit(BBU) at the bottom of the tower. While this configuration is advantageous for both computational efficiency and mitigation of RF loss across the cable, it means the only place along RF can be accessed is at the top of the tower. This forces field technicians to have to climb the tower to measure and debug RF noise problems.

SparkFun ToF Range Finder Breakout for VL6180
12784
This is the SparkFun "Time-of-Flight" Range Finder, a breakout for the VL6180 distance sensor. Unlike most distance sensors that rely reflected light intensity or reflected angles to determine range, the VL6180 uses a precise clock to measure the time it takes light to bounce back from a surface. This affords the ToF Range Finder and VL6180 a great benefit over other methods because it can be much more accurate and more immune to noise. Does this technology sound familiar? Well it should, it's the same means cellphones use to detect when the caller is holding their phone to their ear.
