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.
As data demand ramps ever higher, researchers are looking to innovative amplifier designs to help transport a broader light spectrum through optical fibres, finds Andy Extance
Duncan Ellis shares his views about the increased focus on automation from network operators, and how the physical layer has so far stubbornly resisted the move
Switching off copper networks where fibre has been deployed is the end game, so why are so few operators doing it, wonders Pauline Rigby
With demand for fibre to the premises increasing, Keely Portway looks at the role training plays in ensuring installation skills remain available to meet this growing demand
