Cisco first to deliver 100G at 3,000 km distances without need for regeneration

Cisco announced the successful demonstration and validation of its coherent 100 Gigabit (100G) dense wavelength division multiplexing (DWDM) solution exceeding 3,000 km in reach, without the need for complex Raman optical amplification technology or signal regeneration signals. This distance is 50 percent further than any non-Raman alternative solution on the market today. By eliminating the need for Raman amplification, regeneration and dispersion compensation, carriers can add 100G services on top of existing infrastructures originally designed for 10G technology, providing better investment protection and simplifying network upgrades. The Cisco solution has been tested at a number of service providers and research networks, including US Signal. The performance was also validated by EANTC, the European Advanced Network Test Center.
