Balanced Photodetector
Discontinued PBPD-001

Polarization Diverse Balanced Photodetector


The PBPD-001 Polarization Diverse Balanced Detector performs separate analysis of the two polarization components of an input signal.

Product Description

The PBPD-001 is designed for polarization sensitive measurements that require high signal to noise ratio. The device is fully enclosed in an aluminum box. It has two optical input ports, a power supply port, and a set of output ports (balanced RF output and two monitor outputs) for each polarization component.
