Unbeknown to most people, the erbium-doped fibre amplifier (EDFA) is a superhero that keeps the world talking and communicating. But almost three decades after its invention, it is struggling to do the job alone.
Seaborn Networks has selected Xtera’s C+L band design for its ARBR submarine fibre optic cable system, which connects Argentina and Brazil.
Xtera has transmitted 120Tb/s over a single repeatered fibre in an experiment with University College London (UCL), using a hybrid distributed-Raman/EDFA amplifier with a bandwidth of 91nm.
Subsea fibre optic solutions provider, Xtera is partnering with ADVA in order to develop the capacity and reach of the open networking solutions supplier’s optical transport products. ADVA will license Xtera’s Raman technology for use in both unrepeatered and terrestrial environments.
ALLEN, TEXAS and HAROLD WOOD, LONDON – Xtera a provider of innovative subsea fibre optic solutions has announced that its board of directors has appointed Keith Henderson as chief executive officer and Leigh Frame as chief operating officer.
Xtera has been chosen to supply the ARBR submarine fibre optic cable system, which was developed jointly by Seaborn Networks and Werthein Group, and will connect Argentina and Brazil.
LONDON, UK – Xtera®, a provider of innovative subsea fibre optic solutions, today announces a partnership with Fortress Solutions, a leading provider of telecom equipment repair, to enhance the longevity of its cable systems. As an ISO 9001, TL 9000, ISO 14001 and R2-certified equipment repair service provider, Fortress Solutions will enable Xtera to reduce the turnaround time on legacy equipment and provide a high level of service for its customers.
Xtera Communications has launched its new flex-rate card, a next-generation coherent 100G/100G+ channel card to meet today’s and tomorrow’s ever-growing bandwidth demands.
The new card combines high transmission performance with multiple levels of flexibility in optical networking, including selectable wavelength to operate on either fixed or flexible optical grid and programmable signal protocols on the client side, and programmable modulation format (QPSK, 8QAM, or 16QAM), optical channel rate and spectral efficiency on the line side.
Cost and compatibility can make a compelling case for pushing 100Gb/s bandwidth over a single optical channel, both as individual links and supporting 400Gb/s Ethernet, finds Andy Extance
Robin Mersh takes a look at how the industry is creating next-generation optical access fit for 5G
Technological advances to aid the increasing demand for bandwidth, on the path towards the terabit network, should lead to optical signals that are flexible and adaptive, like water, argues Dr Maxim Kuschnerov and Dr Yin Wang
