Orange tests seven-core fibre reaching 11.2Tbps

Applications and Research

Orange Polska’s Innovation Lab, together with Infinera and the InPhoTech group, recently tested multi-core fibre and Infinera’s ICE6 800G technology. Infinera claims the throughput obtained during the tests was seven times greater than the maximum that can be achieved today using a standard fibre optic cable.

Developed within the InPhoTech group in cooperation with the Maria Curie-Skłodowska University in Lublin and with the support of the Photonics and Fibre Optics Cluster, the multi-core fibre allows transmission in seven parallel cores simultaneously. This means that its capacity is seven times greater than that of a standard telecommunications fibre. Such optical fibres will be produced in Lubartów by IPT Fiber from InPhoTech group.

Infinera says tests have shown that the its hardware allows for 800Gbps data transmission in a single transmission channel. The experiment, conducted in collaboration with Orange, used two channels sending data at a speed of 1.6Tbps in each of the seven cores simultaneously. This gave a total transmission of 11.2Tbps. The quality of the signal measured by such parameters as Q-factor and bit error rate was fully compliant with the applicable standards.

Achieving a maximum throughput of 296.8Tbps is the result of multiplying 800Gbps by 53 channels by seven cores, as the Infinera device allows the placement of 53 channels of 800Gbps each in a single seven-core IPT Fiber, in C-band alone.
