Infinera Expands Open Optical Networking Capabilities

Infinera Groove G30 Network Disaggregation Platform offers new capabilities to enhance optical network efficiency, reliability and flexibility

Infinera, a provider of Intelligent Transport Networks, announces significant enhancements to the open line system (OLS) capabilities of the Infinera Groove G30 Network Disaggregation Platform. The Groove G30 employs a modular sled-based architecture that enables network planners to configure optical transport functionality within an ultra-dense one rack unit (1RU) platform. The new Infinera Groove G30 OLS capabilities enable network operators to enhance optical network scalability and configuration flexibility as end-user services drive increased demand for network capacity.

Open line systems, like the Groove G30, are designed to disaggregate wavelength-division multiplexing transport into functional blocks with open application programming interfaces and end-to-end software-defined network management and control. With an OLS architecture, network operators can potentially reduce vendor lock-in and speed innovation, while lowering capital and operational expenditures.

Key features and benefits of the enhancements identified by Infinera include:

• Optical protection switching (OPSM): New compact pluggable comprising a single optical protection switch providing a cost-effective option for protecting against interface and amplifier failures and fibre cuts
• Colourless, flexible grid add/drop (CAD8/8E): New compact 8-channel pluggable, service-expandable to 16 channels, that provides colourless, flexible grid add/drop to enable the deployment of high baud rate of 64 quadrature amplitude modulation (64QAM) without requiring further reconfigurable optical add/drop multiplexer (ROADM) architectures
• Optical time-domain reflectometer (OTDR): New compact pluggable that supports both in-service and out-of-service OTDR on up to four fibres with distances of up to 100 kilometres, enabling fibre cuts to be quickly located
• In-line amplifier (ILA): Leveraging the existing range of pluggable erbium-doped fibre amplifiers, the Groove G30 OLS can be deployed as a compact in-line amplifier, providing a means of interconnecting data centres over longer distances comprising multiple fibre spans
• Optical power monitoring (OCM): New compact pluggable providing per-channel power monitoring on four ports (i.e. two degrees in two directions) that enhances optical layer monitoring, fast fault detection and isolation and proactive troubleshooting
• 64-port 75 gigahertz (GHz) mux/demux (OMD64): New capabilities that leverage 75 GHz grid filters to support high-baud-rate wavelengths up to 64QAM 600 gigabits per second, with up to 64 wavelengths per filter enabling scalability to 38.4 terabits per second per fibre pair

“The expanded capabilities of the Groove G30 reinforce our commitment to this industry-leading platform and demonstrate the benefits customers realize with open optical transport,” said Julia Larikova, Principal Product Manager for Optical Layer at Infinera. “As end-user applications continue to drive demand for infrastructure capacity, our open line solutions provide an optimal means to scale efficiently while reducing costs.”

The Groove G30 Network Disaggregation Platform is part of Infinera’s expanded suite of packet-optical networking solutions.
