This is really a big deal to transport 100 Gbps on not a single fiber but one wavelength on a fiber. That means other wavelengths on that single piece of glass are transporting other high bandwidth services! This breakthrough continues the bandwidth revolution that will fuel our nations economic recovery.
BASKING RIDGE, N.J., Sept. 25 /PRNewswire/ -- Verizon and Nokia Siemens Networks have taken a step closer to being able to transmit commercial traffic at a speed of 100 gigabits per second (Gbps). The two companies carried out a successful 100 Gbps transmission on a single wavelength for more than 1,040 kilometers over field fiber, setting a new distance record and demonstrating better performance than conventional transmission.
The field trial, conducted on optical fiber on the Verizon network in north Dallas, successfully proved that 100 Gbps signals can be simultaneously transported with 10 Gbps and 40 Gbps signals on the same system with superior results by using advanced optical techniques.
The Nokia Siemens hiT 7500 ultra-long-haul, dense-wavelength-division-multiplexing platform -- combined with multi-level modulation, polarization multiplexing and coherent detection -- allowed the signal to be carried over ultra-long distances at high-data rates with significantly better chromatic dispersion and polarization-mode-dispersion tolerances than conventional systems.

What is Gigabit Ethernet?
Gigabit Ethernet Service (GigE) is a fiber-based network service that utilizes a high speed backbone to provide customers with LAN Interconnection between multiple locations at the native Gigabit Ethernet LAN speeds in specific geographical locations. GigE service delivers a full duplex interface conforming to Gigabit Ethernet standards(1000BaseSX, 1000BaseLX) directly to the customer's LAN. The Telco Company will deploy equipment in the customer's serving central office and connect them using a high speed backbone. This backbone will consist of multiple Gigabit Ethernet trunks. Depending on the customer's location, the backbone may be shared by several customers connected to this service. GigE service provides data privacy and security through the use of 802.IQ closed user groups. Users in a group can only access their own data. Customers will connect to the C.O. equipment using fiber optic LAN extension equipment located on their premises. This, equipment, which is owned by Telco Company, will be the network interface for this service. The customer interface is a single mode or multimode fiber optic connection providing ethernet at 1 gigabit per second. If the facility has extensive bandwidth requirements, GigE is often the most cost-effective option for bandwidth and reliability.
