Test Solutions for Assessing the Polarization Performance of 400G/800G Coherent Systems
Stand 324, 325
7th September 2021
Luna offers a broad range of polarization control and impairment emulation instruments for fast, repeatable and quantitative evaluation of the polarization performance of coherent transceivers, allowing designers to optimize their algorithm and circuitry, customers to compare the performance of different coherent detection systems, and engineers to determine the maximum amount of the impairment under test (PMD, PDL, or fast dSOP/dt) that a system can tolerate. The polarization emulators include first and second order PMD emulations up to 400 ps, PDL emulation up to 20 dB and fast SOP controller/Scramblers up to 11M rad/s.
