Coherent receivers’ polarization demultiplexing, PMD compensation, and PDL mitigation functions must be fully characterized as part of system development and PMD-1000: PMD Source/Emulator PMD-1000: PMD Source/Emulator testing. General Photonics instruments enable all polarization related tests, including: • PMD tolerance, tracking speed, and recovery time • SOP tracking speed and MPC-202: SOP Emulator recovery time • PDL tolerance, tracking speed, and recovery time If the problem is polarization, General Photonics is the answer.
