Our proven culture of innovation and forward-looking vision, combined with demonstrated technology leadership and unmatched financial strength, put Coriant in a unique position to help service providers meet the challenges and opportunities of the hypergrowth era.

Mobile Backhaul

The Coriant portfolio of solutions spans multiple areas of backhaul architectures, from cell sites to aggregation and transport, and supports voice-centric and/or data-centric backhaul requirements. Our portfolio includes a range of products and technologies capable of addressing diverse backhaul requirements and evolution needs, including MPLS-TP based full packet backhaul (PTN), SDH/MSPP-based backhaul, passive WDM for transparent low latency backhaul and front-haul, and high capacity active WDM underlay for backhaul & aggregation.

Transport SDN

Coriant’s Intelligent Optical Control (IOC) solution, the industry’s first solution advancing SDN intelligence for optical networks, paves the way for a more agile, service-centric broadband infrastructure specifically optimized for the hypergrowth era. Coriant IOC combines software-defined service planning, management, and control capabilities with innovative extensions to the SDN framework and enhanced multi-layer interworking and service management.

Multiservice Carriers

Proven in multiservice carrier networks around the world, Coriant offers an industry-leading portfolio of end-to-end packet/optical aggregation, switching and transport solutions, with a common management system for simplified provisioning in multi-layer, multi-domain and multi-protocol networks. Coriant multiservice carrier solutions address a broad range of applications, including migration from SDH to MPLS-TP PTN for access and aggregation networks, high-capacity agnostic grooming and switching for metro core networks, and high-performance optical transport designed for maximum flexibility and ease of upgradeability - 10G to 40G, 100G, and beyond.

Data Center Interconnect

Coriant’s intelligent optical transport solutions offer service providers the flexibility, low latency, and future-proof scalability to meet the most demanding requirements of cloud computing applications and data center interconnect services. Proven in Tier 1 service provider and purpose-built content provider optical networks, Coriant solutions combine high-performance 100G+ coherent optical transport with the industry’s most advanced suite of network and service planning, management, and control software tools.

Carrier's Carrier

Coriant's end-to-end solutions portfolio includes a broad range of carrier-class products that are widely deployed by carrier's carriers around the world, from traditional fixed line suppliers to alternative providers such as utility operators leveraging existing fiber infrastructure to expand their business opportunities. Coriant's solutions include high-performance, low latency packet/optical switching and transport products, as well as highly automated, SDN-enabled network and service management capabilities that dramatically reduce operational costs and complexity while giving service providers the tools to compete through speed of service delivery.

Submarine Networks

The Coriant solution enables operators to transparently connect submarine and terrestrial networks on a single platform with common NSM for seamless service management and control. Key operator benefits include lower cost, reduced latency, less faults and simpler operations due to less equipment in the cable site and higher availability due to optical mesh restoration. Optional OTN switching and GMPLS increase the resilience of the network.

Integrated Packet Transport Network

The Integrated Packet Transport Network solution from Coriant and Juniper Networks integrates multiple layers, creates a simple scalable architecture and closely couples the IP/MPLS and transport layers by deploying best in class optical switching and transport combined with best in class packet switching and routing. The Juniper PTX supercore switch and the Coriant hiT 7300 DWDM platform are the key hardware elements, brought together using Coriant’s integration and multi-layer optimization services.
