Nokia and United Arab Emirates telecommunications services group Etisalat have claimed a capacity record with the trial of a world first field trial of single-carrier terabit-per-second data transmission on a deployed fibre network.

Nokia says a terabit-per-second is enough bandwidth to download the entire Game of Thrones video series in HD in under two seconds – with the trial coming as Etisalat is investing heavily in its core network infrastructure in anticipation of a “massive increase” in traffic from high bandwidth services.

According to Nokia, the field trial demonstrates that Etisalat’s existing network can support the higher optical wavelength bit rates that will be required to support high-bandwidth services such as 5G extreme mobile broadband (very fast wireless to the mobile), fibre-to-the-home (FTTH) and Data Center Interconnect (DCI) cloud services.

“Higher bit rates per wavelength provide power and space savings, improved network simplicity, increased spectral efficiency and capacity, and ultimately reduced cost per bit compared to optical networks composed of lower rate channels,” Nokia notes.

“The trial successfully transmitted a record 50.8 terabits per second using multiple wavelengths, each with a net information rate of 1.3 terabits per second, over a 93-km fibre route of Etisalat’s wavelength division multiplexing (WDM) network. Leveraging a single optical carrier operating at 100 Gigabaud, the terabit wavelengths employed Nokia Bell Labs-pioneered probabilistic constellation shaping, or PCS, to intelligently shape the signal to achieve maximum capacity for the specific fibre route.”

Esmaeel Alhammadi, Senior Vice President, Network Development at Etisalat, said: "We are pleased to have partnered with Nokia Bell Labs to demonstrate that our optical network is capable of transporting a terabit per second over a single wavelength, and a total per-fibre capacity of over 50 terabits-per-second.

“Increasing network capacity helps us to provide bandwidth-hungry services such as 5G extreme mobile broadband, fibre-to-the-home and DCI for enterprises.”

“The introduction of 5G will require a network that can support dramatic increases in bandwidth in a dynamic fashion,” said Sam Bucci, Head of Optical Networking at Nokia.

“This ground-breaking trial with Etisalat is testimony to Nokia’s commitment to continue to invest in coherent and optical component technologies required to meet the 5G networking challenge at the lowest total cost of ownership for our customers.”
