1310nm Polarization Beam Splitter/Combiner
The 1310nm Polarization Beam Splitter/Combiner (PBS/PBC) is a passive fiber optic device designed to separate or combine orthogonal polarization states at the 1310nm wavelength. It can split randomly polarized light into two orthogonally polarized output signals or combine two orthogonally polarized input signals into a single output fiber while maintaining low insertion loss and high extinction ratio.
Manufactured using polarization-maintaining (PM) fiber technology, this 1310nm PBS/PBC provides stable polarization performance, high directivity, and excellent optical reliability for advanced photonic systems. Port 1 and Port 2 are configured with PM fiber, while Port 3 is available with either single mode fiber (SMF) or all-PM fiber configurations to meet different application requirements.
Featuring compact size, low insertion loss, and reliable polarization characteristics, the device is widely used in optical communication systems, PM fiber lasers, optical amplifiers, fiber sensing, coherent transmission, and polarization control applications.
