偏振分集接收器-Polarization Diversity Received
The OPTIPHASE ? PDR is a highly efficient and cost effective Polarization Diversity
Receiver for use in interferometric measurement and sensing systems. The PDR
eliminates polarization fading in fiber optic interferometers without significant
degradation in the signal-to-noise ratio.
The PDR serves as a receiver to fiber optic interferometers that allow for
polarization fading through random birefringence fluctuations. The three
independent polarized receivers assure that at least one of the outputs have high
interferometric visibility.
Input light is split by a 1 x 3 fiber optic coupler made with SMF-28 with low
polarization dependent loss. The three outputs are pigtailed to polarized PIN
photodiodes (InGaAs). The polarizer orientation of the photodiodes is 0, +60 and -60
degrees.
FEATURES & BENEFITS:
Eliminates polarization fading
Maintains signal-to-noise ratio
Compact package
PCB mountable
1550 or 1310 nm
