TeliaSonera conducts single wavelength 100 Gbps trial

TeliaSonera (Stockholm: TLSN.ST) is joining the growing chorus of service providers that want to better understand the capabilities of 100 Gbps networking.

As one of the first real-time, single wavelength 100G field trials in Europe, TeliaSonera demonstrated a single wavelength, real-time coherent 127 Gbps PM-QPSK (Polarization Multiplexed Quadrature Phase Shift Keying) modem from Opnext (NASDAQ:OPXT) in its network running through Sweden.

One of the unique attributes about the trial was that it did not require the traditional optimization that other carriers have had to go through to balance optical impairments on TeliaSonera's existing fiber. Opnext claims that service providers can upgrade their existing line systems to 100 Gbps without major network upgrades or having to deploy external dispersion compensation.

European service providers aren't the only ones dabbling in 100 Gbps network deployments, however. U.S.-based providers including AT&T (NYSE: T), Qwest (NYSE: Q) and Verizon (NYSE: VZ), not to mention end-users such as NYSE Euronext are in various stages of trials and deployments of 100 Gbps optical technology. FierceTelecom itself will address the challenges service providers face in making their respective migrations to 100 Gbps today in our webinar, 100 Gbps networking.
