Coriant offers open line system for long-haul DCI applications


Coriant has introduced an open optical line system that has been designed to meet the requirements of long-haul data centre interconnect (DCI) as demand for high-capacity connectivity between geographically-dispersed data centre sites continues to grow. The new Coriant 7300 Open Line System (OLS) complements the company’s Groove G30 transponder/ muxponder DCI platform, and is compatible with open systems from third-party vendors. Currently in customer trials, the new 7300 OLS exploits the optical layer performance capabilities of the Coriant hiT 7300 multi- haul transport platform. The OLS offers a broad portfolio of amplifiers that maximise capacity and reach, even under conditions with strong and inhomogeneous optical impairments, the company claims. It features sophisticated optical link control that delivers high engineering margins. Optical link control ensures robust performance by mitigating the influences of degrading fibre quality or non-ideal fibre types, environmental interference, and other service-impacting transmission challenges. In addition, the open line system supports


core data centre equipment practices, including front-to-back airflow and AC power. With a compact and custom-built shelf design that maximises space utilisation and power efficiency, the 7300 OLS enables simplified management and control in third- party managed network environments via support for software-defined networking (SDN) integration enabled by the Coriant Transcend SDN controller. ‘Flexibility, openness, and stability are


increasingly critical in long-haul networks as dynamic and hyperscale traffic flows between data centres drive new design criteria and disaggregated deployment models,’ said Stefan Voll, vice president of product management, Coriant. ‘The 7300 OLS combines best-in-class optical layer performance with data centre optimised features in an open system design.’ www.coriant.com


XKL offers DarkStar inline amplifiers


XKL has introduced a new generation of inline amplifiers that integrate with its DarkStar family of optical transport appliances, making it possible for customers to extend their network reach without needing to employ skilled optical engineering staff. High noise figures in optical amplifiers are a barrier for many long-haul applications, XKL says. Incorporating both Raman and erbium-doped

Anritsu BERTWave MP2110A speeds up 100G module production lines


Anritsu has launched the BERTWave MP2110A, which is optimised for inspecting 100Gb/s multi- channel optical modules. It is an all-in-one bit error rate tester and sampling oscilloscope used to evaluate optical modules, including 100 Gigabit Ethernet, InfiniBand EDR and 32G Fibre Channel. Not only does the all-in-one MP2110A design


reduce capital investment, the instrument contains several features to shorten measurement times and increase yields on production lines and in development environments. High-speed sampling shortens measurement times, and the high-sensitivity error detector performance improves yields to cut production costs of optical modules and devices, according to Anritsu. Unlike previous measurement environments


ADVA’s FSP Network Hypervisor for optical network virtualisation


ADVA Optical Networking has launched its FSP Network Hypervisor, which it describes as a key component in the drive to virtualise optical networks. The software has been developed to help service providers automate service discovery and service activation, when paired with the ADVA FSP 3000 platform. The Hypervisor creates an abstracted view of the underlying physical infrastructure, and presents it to a software defined networking (SDN) controller, helping to decouple the complexities of managing photonic transmission systems from the hardware layer. Already showcased in multiple public demos and various proof-of-concept installations, the FSP Network


that required two instruments for measuring the BER and analysing eye patterns, the MP2110A supports simultaneous measurements. To shorten takt times on production lines, the MP2110A maximum sampling speed has been increased to 250ksamples/s, reducing eye pattern analysis times for eye mask tests by 75 per cent. The MP2110A also supports options for expanding the built-in bit error rate tester (BERT) to four channels at up to 28.2Gb/s, and the built-in sampling oscilloscope to two channels. Thus, the MP2110A can perform simultaneous transceiver BER measurements of multi- channel optical modules, such as QSFP28, and simultaneous two-channel eye pattern analyses, reducing measurement times by up to 65 per cent compared to previous measurement systems. www.anritsu.com


Hypervisor has been engineered to work with all open source and commercial SDN controllers. With Hypervisor software, service providers can move away from static networks to far more automated and responsive cloud architectures. It provides information on topology discovery and abstraction, connectivity management, path computation and notifications. This can be used to create self-provisioned services, automated resiliency and optimised resource utilisation. These are critical features for any carrier or internet content provider seeking real- time cloud connectivity and multi-layer network optimisation, especially for software-centric network architectures, such as the Central Office Re-Architected as a Data Center concept. www.advaoptical.com


fibre amplifiers (EDFAs), XKL’s amplifiers have low noise and a multi-stage design incorporating the balanced sequence of dispersion compensation, equalisation, and tilt filters necessary to groom the signal in a poor-quality fibre. Its inline amplifiers are all Class 1M laser products, thus allowing for simple deployment and management. ‘Network flexibility and amplification manageability continue to be a key requirement


for our customers,’ explained Chad Lamb, chief systems architect for XKL. ‘By using XKL’s DarkStar inline amplifiers, organisations are able to extend their metro and regional networks. Through a familiar router-like interface, and using standard protocols that easily integrate into network management schemes, our amplifiers are designed for agile transport requirements.’ www.xkl.com
