US Signal Tests Cisco's 100G Coherent DWDM

US Signal, a provider of regional transport, data center and IP services, has completed field trials of 100G coherent DWDM based on the Cisco ONS 15454 Multiservice Transport Platform (MSTP) system. The 100G coherent trial was performed over an in-service 10G-engineered network between Chicago, Ill. and Kalamazoo, Michigan. Cisco said this trial confirmed that US Signal can deploy in-service, 100G coherent technology on networks originally designed for 10G transmission without any re-engineering. US Signal is also leveraging the Cisco Aggregation Services Router (ASR) 9000, Cisco Nexus 5000 Series Switches and the Cisco Unified Computing System (UCS) to scale its IP backbone and service capability. http://www.cisco.com

  • Earlier this year, Cisco acquire CoreOptics, a designer of digital signal processing (DSP) solutions for high-speed optical networking, for approximately $99 million in cash and retention-based incentives.

    CoreOptics developed 10G and 40G Distortion Tolerant MSA Modules and IC solutions for optical networking. Its Electronic Distortion Equalization (EDE) technology leverages Maximum Likelihood Sequence Estimation (MLSE) to address the physical layer challenges of optical fiber transmission. CoreOptics' algorithms are implemented using a DSP architecture.
