Contact Sales for Full Specifications

This dual-input device comprises one signal input and one local oscillator input. These signals are both split into TE (X) and TM (Y) orthogonal polarized light by inline polarization beam splitters (PBS). These are then allowed to interfere via two inline mixer sections, comprising splitters and couplers. They are then finally split to generate 4 output signal pairs, XI, XQ, YI, and YQ where X/Y is polarization and I/Q is phase.
