PBPD-001 Polarization Diverse Balanced Photodetector
Polarization diverse balanced photodetector that analyzes the two polarization components of an input optical signal separately.
- Wavelength range
- 1310±50nm
- Polarization crosstalk
- <25 dB
- PDL (before polarization splitting)
- <0.25 dB
Overview
The Luna PBPD-001 Polarization Diverse Balanced Detector performs separate analysis of the two polarization components of an input signal. It is intended for polarization-sensitive measurements that require a high signal-to-noise ratio.
The device is fully enclosed in an aluminum box. It has two optical input ports and a power supply port. For each polarization component, it provides a set of output ports: a balanced RF output and two monitor outputs.
The PBPD-001 is suitable for integration into polarization-sensitive optical coherence tomography (OCT), fiber sensor and optical measurement systems. The manufacturer lists this product as discontinued.
