An open access network approach allows for sharing optical layer resources like fibers and optical spectrum among different services and operators at the same time.
We demonstrate the successful trial of 400 to 600 Gb/s per carrier over Orange live network.
A tunable, bandwidth variable, SP-IQ (Single Polarization In Phase and Quadrature) transmitter based on the hybrid integration of passive polymer PolyBoards with InP photonic chips and InP-DHBT ele
This paper presents the evaluation of 3D beamforming field measurements in the testbed in Dresden.
We demonstrate a field trial WDM transmission over two spans of 18dB and 16.5dB loss, with average channel rate of 475Gb/s over >100nm optical bandwidth, and with 250Gb/s 16QAM real-time transpo
We report on a 107-Gb/s field trial carrying live HDTV traffic over a 504-km in-service DWDM route, proving that commercial systems designed for 10G/40G can be upgraded to 100G without impacting ex
The rapid progress in recent years of subscriber-to-subscriber dialling over toll lines has necessitated a departure from d.c. signalling in use on the shorter junctions between urban exchanges.
We successfully tested the suitability of probabilistically shaped constellations in a German nationwide fibre ring of the R&D field test network of Deutsche Telekom.
Operating a network close to its limits while assuring long-term health seems incongruous.
Coordinated Multi Point (CoMP) technology has been considered as a promising means to mitigate inter-cell interference and has great potential to significantly improve the system capacity as well a
