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 Spectra February 2023 IssueDual-Port Test SolutionThe FTBx-88480 dual-port test solution from EXFO Inc. enhances technician productivity for fiber optic transmission rates from 1 to 400 G.
