Coherent Routing

Build application-optimized IP-optical networks using coherent optics

The Nokia Coherent Routing solution brings together the power of pluggable digital coherent optics (DCOs) with Nokia’s advanced IP service routers, optical transport systems and network automation expertise to enable more efficient and scalable IP-optical network designs.

Is your network ready for 400GE and beyond?

Relentless demand for more network capacity is driving service providers and cloud builders to look at new approaches to scale IP and optical network infrastructure more efficiently. Fortunately, rapid silicon technology advances have fueled a new breed of small form-factor pluggable coherent optics. Equipping these DCOs directly into IP router platforms and line cards allows IP routers to interconnect directly and efficiently over coherent DWDM wavelengths up to 1,000 km long, while achieving port densities similar to those of short reach 400GE client optics. 

Support 400GE pluggable DCOs without compromises

Our high-performance IP routers are design-optimized to support pluggable coherent optics at full scale without compromises in port density or operating conditions. Nokia 7750 SR-s, 7730 SXR, and 7250 IXR routing platforms and line cards accommodate a full range of 400ZR and 400ZR+ optics today, while being ready to support 800G pluggable coherent optics as they become available in the future.
Superior power dissipation and cooling of port cages also provides ample headroom to equip powerful 400ZR+ optics with 0 dBm launch-power. This allows you to optimize capacity and reach for Coherent Routing applications over multi-span and ROADM-enabled fiber routes and use the added flexibility of ROADM-enabled optical transport networks to support multi-point applications. 

Deploy Coherent Routing applications anywhere

Our portfolio of compact optical line systems and optical add-drop multiplexers (OADMs) enables you to efficiently deploy a full suite of Coherent Routing applications across any distance and topology. Fixed OADMs with powerful in-line amplifiers let you maximize capacity and reach for point-to-point applications such as IP access and data center interconnect. 

Coherent Routing leverages our ROADMs to let you provision point-to-point wavelengths across more complex fiber topologies, by enabling low-latency IP express links that carry aggregated IP traffic from source to destination ports with the fewest possible routing hops and optical-electrical transitions. 

Coordinate and automate your IP-optical network

The Nokia Network Services Platform (NSP) completes the solution with cross-domain IP-optical management that lets you efficiently coordinate and automate IP-optical network operations from end to end, through a single pane of glass. It offers a growing catalog of pre-validated applications and use cases to help get your teams up to speed quickly, with minimal cost and risk.
