1×2 1310/1480/1550nm Polarization Beam Combiner (PBC)

A 1×2 1310/1480/1550nm Polarization Beam Combiner (PBC) is a high-precision optical device designed to combine two orthogonal polarized light beams (P-polarized and S-polarized) into a single output. It supports common communication wavelengths of 1310nm, 1480nm, and 1550nm, offering low insertion loss, high return loss, and high extinction ratio for optimal optical performance. Capable of handling up to 500mW optical power, this PBC is widely used in fiber optic communication systems (DWDM, optical amplifiers, optical switches), optical measurement and sensing, laser systems (laser cavities, polarization control), and quantum communication and computing. Its 1×2 structure makes it an ideal solution for polarization control, optical signal processing, and high-precision optical experiments.
