Use of polarization freedom beyond polarization-division multiplexing

In this paper, we propose and experimentally demonstrate a pseudo-PDM of four states (PPDM-4) system over standard single-mode fiber (SMF) to explore the use of polarization freedom.

Transoceanic-Class WDM/SDM Transmission of PDM-QPSK Signals

We demonstrated long-haul transmission of 32-Gbaud PDM-QPSK over cou-pled 12-core fiber with standard cladding diameter. Error-free transmission after FEC was achieved up to 7280 km.

Polarization-division multiplexing

The major problem with the practical use of PDM over fiber-optic transmission systems are the drifts in polarization state that occur continuously over time due to physical changes in the fibre environment.
