ComputerWorld reports Chinese telecom firm ZTE has conducted a field test of optical networking equipment capable of transferring data at 1.7Tbps over a distance of 1,750 kilometers. The test was done with standard single mode fiber optic cable, using eight channels with a capacity of 216.4Gbps.
The WDM-based system transported the data using eight channels, each with a capacity of 216.4Gbps, according to ZTE.
WDM (Wavelength Division Multiplexing), which is mainly used by operators in their core networks, sends large amounts of data using a number different wavelengths or channels over a single optical fiber.
The distance during ZTE's demonstration was 1,750 kilometers (1,087 miles), and the company used a standard single mode fiber optic cable, it said.
ZTE didn't detail when in expects to see products that can handle 200Gbps per channel. The goal with the demo was to show that an "upgrade from a 100Gbps transmission system to a 200Gbps system is possible," the company said.
