NTT Electronics starts shipping 400G coherent co-package device for 400ZR/ZR+ operation. NTT Electronics starts shipping 400G coherent co-package device for 400ZR/ZR+ operation. (NYSE: COHR), a global leader in photonics, today announced it will demonstrate multiple co-packaged optics (CPO) technologies at OFC 2026 in Los Angeles, highlighting the company's broad portfolio and vertical technology stack. At the heart of this evolution are 400G Coherent Optics, which integrate optical and electrical components to enable high-speed, long-reach communication. Compared to earlier 100G or 200G systems, 400G solutions offer improved spectral efficiency, greater data capacity, and enhanced scalability. AI and cloud traffic surged, driving inter-data-center bandwidth purchases up 330% from 2020 to 2024. By 2025, operators moved past 400G, with 800G becoming the mainstream, and early pilots pushing into 1. In early 2024, primary North American. Based on Skorpios' full C-band, 70kHz linewidth, uncooled tunable laser technology, DWDM capable full coherent transceiver devices will be available as TROSA, Engine (with DSP) or QSFP/OSFP module. ✨ 400G D-EML laser — industry-first, >100 GHz.
