Dicon PM-1×4-13/15-9-FC

The Dicon PM-1×4-13/15-9-FC is a polarization-maintaining fiber optic splitter that divides a single optical input into four output paths while preserving polarization state. Designed for dual-wavelength operation at 1310 nm and 1550 nm, this device serves telecommunications, coherent optical, and fiber sensor applications where polarization fidelity is critical.
