Oclaro Inc. has released the MI 8000XM, a low-power 100-Gb/s MSA-compliant coherent transponder that leverages its competencies in indium phosphide and lithium niobate materials technologies, and its vertical integration in optical components. The transponder uses a polarization-multiplexed quadrature phase-shift keying modulation format combined with coherent detection, a technology for enabling 100-Gb/s and higher optical transmission, and for delivering the scalability and flexibility needed for transmitting more bandwidth cost-efficiently over fiber optic networks. The instrument integrates the latest-generation digital signal processor with a control and management implementation to deliver suitable performance in a module that can be integrated into network equipment. It complies with the OIF 100-Gb/s MSA Implementation Agreement. It uses a low-power digital signal processor large-scale integrated circuit supplied by NTT Electronics Corp.
