1310nm or 1550nm φ0.9 Polarization-Maintaining Connectors With High Extinction Ratio
As a special kind of optical fiber, the polarisation-maintaining fiber Connectors can ensure the constant direction of linear polarization, improve the coherent SNR, and realize the high precision measurement of physical quantity. Generally PM Connectors used in special scenarios, such as fiber optic sensors, fiber optic gyro, fiber optic hydrophones, fiber optic current sensors, and polarization preserving wavelength division multiplexers. They are also commonly used in the connection between the source laser and the modulator.
