Openreach uses Adva’s FSP 150 for new 10Gbit/s EAD service
A dva Optical infrastructure division of BT Group, has deployed its FSP 150 system as the foundation of the new EAD 10G service. This point-to-point 10Gbit/s Ethernet Access Direct service will provide Openreach’s customers with 10 times the bandwidth at little more than twice the price of the current 1Gbit/s product. Openreach is utilising Adva’s technology to meet the rapidly- growing demand for bandwidth from enterprise customers. The new EAD 10G solution saves space, enables flexible deployment and is said to be less expensive than other high-bandwidth products based on optical fibre. The service supports the sector’s increasingly stringent timing requirements with Synchronous Ethernet. It will also enable Openreach to roll out more EAD functionality in the future. Networking has announced that Openreach, the
Kerry Brennan, general manager, Fibre Services, Openreach, commented, “With FSP 150 as the foundation, we’ve created the ideal EAD solution and many of our business and infrastructure customers have already chosen to upgrade. Throughout the project we’ve collaborated closely with Adva’s team. “We know real estate is at a premium in many locations so EAD 10G uses rack space more efficiently. It’s a single-fibre working solution, using only one physical fibre for both, transmit and receive directions, so installation and repair are simple and inexpensive. Customers will also save on power compared with legacy solutions. But the key benefit has to be that EAD 10G delivers 10 times the performance of 1Gbit/s at no more than 2.5 times the price.” The new service is built on the latest 10G variant of the FSP 150 range. With its Etherjack

substantial benefits to many UK enterprises. Our FSP 150 ensures the new 10G service is enhanced with EAD Synchronous Ethernet so Openreach’s customers can utilise technologies that require precise frequency synchronisation, giving them access to a host of new business opportunities. With intelligent demarcation and aggregation, its clients will receive even more than high-bandwidth point-to-point connectivity. Enterprises can now tackle their growing bandwidth needs and at the same time drive down cost.”
operations, administration and maintenance tools, it’s a suitable platform for provisioning differentiated Ethernet services at up to 10Gbit/s. The FSP 150 also delivers strict service level assurance for carrier and enterprise applications through its extensive quality of service management. The solution features a variety of service protection capabilities and hardware redundancy options and it comes complete with a resilient temperature-hardened design.” Sarah Mendham, sales director at Adva, said, “EAD 10G is going to bring
High-speed optical modulators adapted for communications and sensing E lectro-optic modulators, which can switch light on and off within just picoseconds, are enabling ever faster Molecules absorb light at well-defined particular colours or optical frequencies. Usually such characteristic frequencies are located in the infrared techniques have been developed, rapid and precise high-resolution sensing is still a challenge.

Precisely measuring a set of such absorption dips unambiguously identifies the molecules and quantifies their abundance in the probed environment. absorption spectroscopy is sensitive and nonintrusive, it finds an increasing number of applications, from biomedical diagnostics to atmospheric sensing. In the gas phase, the absorption lines are narrow so that high spectral resolution is needed to distinguish the different lines.

The same tools have now been harnessed for high-speed and accurate molecular sensing, as reported by an international collaboration around Dr. Nathalie Picqué, Max Planck Institute of Quantum Optics and Ludwig-Maximilians- Universität Munich, in a letter published in Nature Photonics, 21 December 2015.

Such unique combination holds much promise for trace gas sensing, a domain relevant to physics, biology, chemistry, industry or atmospheric sciences. “Furthermore, the frequency-agile frequency comb generator might also become an enabling tool for applications beyond spectroscopy, like for arbitrary waveform generation, radio- frequency photonics, optical coherence tomography or microscopy”, concludes Dr. Ming Yan, a post-doc working at the experiment.

They use modulators and a nonlinear optical fibre to produce two frequency combs, each with more than a thousand evenly spaced infrared spectral lines with a remarkably flat intensity distribution. Line spacing and spectral position can be selected quickly and freely by simply dialing a knob. Such frequency-agile optical combs offer unprecedented freedom when interrogating a molecular spectrum via a powerful technique called multiplexed dual-
