The first channel at 800G is a reality for Ciena and BT

A further innovative leap for BT that after the successful tests carried out in March 2013, to start with CienaCorporation, a new series of highly pioneering tests on the operator's optical network infrastructure in the United Kingdom.

A further innovative leap for BT that after the successful tests carried out in March 2013, to start with CienaCorporation, a new series of highly pioneering tests on the operator's optical network infrastructure in the United Kingdom.

Previous tests included 100, 200 and 400G transmissions and the implementation of a super channel at 800G, which is equivalent to the simultaneous transmission of seven high definition DVDs in one second.

Proved the possibility of supporting Terabit speed on the BT central backbone, thanks to the use of WaveLogic transmitters 3 and implementing single or multiple channel techniques. The tests were carried out on fiber cables with high dispersion of polarization modes (PMD), not suitable for traditional 10G operations, which strongly highlighted the robustness of Ciena's coherent technology and its ability to be implemented in any environment and condition.

The BT network, based on the Ciena6500 Packet-Opticale optical package on the 4200 Advanced Services platforms, supports the entire portfolio of services provided by the operator including super-fast broadband and Ethernet services. For a specific test, 400G traffic was transmitted and monitored throughout the network using a 16QAM modulation and operated perfectly maintaining the wavelength between 40 and 100G QPSK-based. It has allowed us to strengthen the simplicity offered by Ciena's consistent technology in the migration process. Finally, with Wavelogic 3, BT will be able to gradually increase its network capacity according to the requirements of its wholesale and business customers and at the same time reduce the related costs and reduce the impact on the environment.

BT has always been a strong pioneer in the field of networking, a characteristic that can be traced back to the origins, when the Electric Telegraph Company, the first British telecommunications company, was established. From then until today, a period characterized by the recent explosion of global connectivity, we have always looked for innovative elements to update our infrastructure and provide more and more bandwidth for new generation applications and services. These tests are the latest proof that we are moving in the right direction and we are extremely proud of the key role we play in the history of communications. comments Neil J. McRae, chief network architect, BT.

The demonstration of these high-capacity transmissions describes the value of the consolidated collaboration between Ciena and BT. BT's future network will allow the company to differentiate itself enormously from its competitors and to continue to offer its users cutting-edge services; all while keeping costs under control and limiting the environment. Through this partnership we further consolidate our partnership and the intention to work together to develop networks capable of supporting new highly programmable services, leveraging the entire Ciena offer to create increasingly interesting services and applications for BT users. confirmation Franois Locoh-Donou, senior vice president, global products, Ciena.
