Fiber-coupled Balanced Detector Module Fbd-100 S/i

These Fiber-Coupled Balanced Detector Module FBD-100 S/I subtracts two input signals from each other, resulting in the cancellation of common mode noise. This allows small changes on the signal path to be extracted from the interfering noise floor. Sonostar offers the type with bandwidth of DC to 100 MHz. It is available with either Si (FBD-100S versions) or InGaAs (FBD-100I versions) photodiodes. To improve the measurement capabilities in applications where it is desirable to measure a comparably weak frequency modulated signal over a strong CW background signal, an AC-coupled version of the PDB Series is offered.
The Fiber-Coupled Balanced Detector Module FBD-100 S/I of detectors use two balanced photodiodes and an ultra-low noise, high-speed transimpedance amplifier. The design allows an improved matching of the balanced photodetectors to achieve an excellent common mode rejection, leading to better noise reduction.

The detectors have two optical inputs with removable and interchangeable connectors a either FC/PC or FC/APC a for easy adaptation to either fiber-coupled or free-space applications.
