SAXONBURG, Pa., Sept. 26, 2025 (GLOBE NEWSWIRE) -- Coherent Corp. (NYSE: COHR), a global leader in photonics, announces the industry’s first QSFP28 Dual Laser 100G ZR solution that enables broadband providers to efficiently maximize capacity on existing fiber infrastructure. The Coherent 100G ZR QSFP-DCO is the industry’s first dual laser QSFP28 digital coherent optics (DCO) module for single fiber, bi-directional applications – a breakthrough for network operators in access and aggregation networks. “Traditionally, the benefits of coherent optics have been limited to dual fiber networks, but innovations like these give operators the ability to leverage the performance of coherent optics, across a range of network architectures,” said Sunny Sun, Executive Vice President, Communications at Coherent. “This innovation enables us to seamlessly deploy the benefits of coherent optics more pervasively throughout our network and gives us greater flexibility to expand our network to new and underserved communities,” said Elad Nafshi, Chief Network Officer at Comcast. The solution is powered by the Steelerton™ DSP, the proprietary low-power digital signal processor (DSP) by Coherent that is optimized for 100G deployments.
