Request InfoLumentumSAN JOSE, Calif., March 24, 2015 — NeoPhotonics Corp. has announced new low power-consumption 56-Gb/s externally modulated lasers (EMLs) and drivers for both 4 × 100-Gb PAM4 and 8 × 50-Gb NRZ client-side 400-Gb transceivers. The products enable two types of 400-Gb interfaces. With a PAM4 modulation scheme, the EML and driver can achieve a 100-Gb/s data rate with a single laser. A 400-Gb interface will use four wavelengths with PAM4 modulation. Meanwhile, a traditional NRZ modulation scheme with an EML and limiting driver can deliver 400-Gb of capacity with eight wavelengths.See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 3/29/2024Pump Laser ModulesThe uncooled pump laser modules from Coherent are made with Coherent’s G10 series laser diode technology and are meant to be used in submarine and both single- and dual-chip terrestrial...Photonics.com 1/5/2024PAM4 Optical DSPsThe Perseus and Spica Gen2 from Marvell Technology, Inc. are optical PAM4 digital signal processors (DSPs) that can be used in AI, accelerated computing, and cloud services applications by optimizing...Photonics Spectra February 2023 IssuePolarity DetectorThe RD-P Remote-head Polarity Detector from JGR Optics Inc. integrates with the IL/RL measurement system to reduce testing time and cost of multifiber optical cable assemblies.
