ADVA’s new 400ZR DCI OLS

Large-scale DCI networks need to rapidly and affordably expand to address soaring data demand 400ZR technology meets requirements for high capacity and high density Next-generation ADVA DCI open line system is fully optimised for 400ZR and tested with leading pluggable transceivers. ADVA has launched the FSP 3000 data centre interconnect (DCI) open line system (OLS) specifically designed for 400ZR technologies. ADVA says the device addresses the most urgent challenges for network operators by enabling commercial deployments of DCI infrastructure based on 400ZR. High-density, cost- effective, open solutions that are optimised for point-to-point applications up to 120km, will be key to rapidly expanding DCI

capacity to meet soaring data demand.

capacity data centre networks. The launch of our new DCI OLS will be key for operators. It provides the missing link to real-world deployments of open infrastructure built with 400ZR interfaces,” said Christoph Glingener, CTO, ADVA. “Our pedigree in the DCI space is second to none. We were the original DCI company, enabling Fortune 500 companies around the globe to harness the cloud with best- in-breed solutions. For more than 25 years, our innovation

has helped the industry evolve. Now we’re giving large-scale DCI providers what they need to move forward. Our next- generation FSP 3000 DCI OLS offers a way to inject ultra- high capacity while reducing total cost of ownership and operational complexity. What’s more, the ADVA FSP 3000 DCI OLS solution is designed to optimise performance with 400ZR-compliant optics from any vendor.” For more information, visit www.adva.com

Currently undergoing customer testing and

evaluation, ADVA says the DCI OLS has demonstrated seamless interoperability with 400ZR pluggable transceivers. The solution is fully compliant and, it is claimed, outperforms the 400ZR standard, and with data centre-compatible open APIs, it can be directly integrated into SDN environments. “Today we’re announcing a major milestone for open, high-

Birefringent polarisation fibre from iXblue

iXblue Photonics has released a highly birefringent polarisation fibre targeting high-volume production of compact fibre- optic gyroscope operating at 1550 nm. iXblue says the fibre, based on 30 years’ experience in Polarisation Maintaining Gyro fibre, features the highest birefringence, and shortest beath length available in the industry – 0.9mmat

633 nm. Thus, it offers high Polarisation Extinction Ration for fibre-optic gyro coils, evenwith extremely small radius (below 30 mm). The company says this record birefringence has no impact on the other key optical specifications as attenuation, mode field diameter and numerical aperture remain the same to ensure low loss and excellent coupling under bent

configuration. “Thanks to our Tiger type

of the stress rods and Bow-Tie type leads to severe deformation of the core. We also worked on the clad shape in order to get good recognition by standard PM splicing equipment, the spliceability with standard PM panda fibre is excellent which is a key point for seamless integration at our customers manufacturing floor”. iXblue says This new “IB” fibre opens new possibilities for FOG manufacturers as they are now able to manufacture tiny coils while keeping a good PER over operational temperature range. The external coating diameter is reduced to a remarkable 128 µm value for an 80 µm clad fibre, helping further to reduce the outside size of coils and limiting the Shupe effect.

fibre – also called elliptical clad – we have been able to work on the material composition of the clad in order to increase the birefringence stress and maintain a perfect round shape for the core,” explains Thomas Villedieu, product manager at iXblue Photonics. “With other technics, you do not get such level of flexibility. For instance, with Panda type fibres you are quickly limited by the size
