1480nm 1x2 Polarization Beam Combiner/Splitter
Firsol 1480nm 1x2 Polarization Beam Combiner/Splitter is a passive fiber optic component designed to split one optical signal into two orthogonally polarized outputs or combine two orthogonally polarized input signals into a single output fiber. Operating at a center wavelength of 1480nm with a ±40nm operating range, it offers low insertion loss of ≤0.6dB, a high extinction ratio of ≥22dB, return loss of ≥50dB, and directivity of ≥50dB. CW optical power options from 0.5W to 10W are available for standard and high-power systems. Ports 1 and 2 use polarization-maintaining fiber, while Port 3 can be configured with single-mode fiber or PM fiber. Its stable polarization performance makes it suitable for fiber amplifiers, fiber lasers, coherent communication systems, optical sensing, and other polarization-maintaining fiber applications.
