Network automation can save operators up to 81% in management costs.
According to research carried out by Nokia, in collaboration with research firm Analysys Mason, operators can expect up to 81% cost savings after deploying optical network automation for network and service lifecycle management. To quantify optical network automation’s benefits across CAPEX, OPEX and revenue generation opportunities, Nokia and Analysys Mason interviewed global operators who have deployed network operations and service automation processes with Nokia WaveSuite. WaveSuite is a complete platform that
90% savings in operational costs. This enabled a Tier-1 North American operator to improve their win rates by 5x. Nokia says optical network automation is a key enabler for network operators to maximise optimisation, efficiency, reliability and scale, as well as TCO savings and asset monetisation for revenue generation. This comes amid surges in data traffic from sources such as AR/VR, AI/ML and IoT, as well as the growing trend of more programmable optical networks. Despite this, adoption remains slow due to new challenges with increasing OPEX.
labour taken to complete service order orchestration, service fulfilment and service assurance processes; CAPEX avoidance of 26% by optimising network resources and retiring legacy network equipment; up to 10% uplift in anticipated revenue from the improved win rates, combined with an accelerated time-to-market for services and the ability to offer differentiated services through optical network slicing and network-as-a- service business models; and decreased time taken for service order fulfilment, from an average of 10 days to 24 hours, contributing to around
automates optical transport to lower costs and increase reliability and go to market faster with new services for increased revenue. Analysys Mason found the benefits of optical network automation spanned multiple areas of network and service lifecycle management, including reduced network lifecycle management operational costs by up to 56% by simplifying complex network operations tasks for shorter time to provision, configure, deploy and manage optical networks; operational cost savings
of up to 81% for service delivery by reducing the
Top firms trial hollow core fibre
Telia Lithuania taps Ciena for 800Gbps wavelength service
lyntia, Nokia, OFS|Furukawa Solutions and Digital Realty (Interxion) have successfully carried out a field trial in a real environment to demonstrate the potential of hollow core fibre technology. Prior to implementing the technology in a real environment, pilot tests were carried out in a laboratory in Paris by Nokia Bell Labs. The initial results showed a significant reduction in latency by more than 30% and a considerable decrease in non-linear effects compared to traditional optical fibre. The pilot tests in Paris demonstrated data rates of 800 Gbps and 1.2 Tbps. The results showed that hollow fibres have the potential to break through the non-linear Shannon capacity limit of solid-core fibres.
The recently completed field trial in Madrid confirms the feasibility and effectiveness of hollow core technology. The trial demonstrated a round-trip latency reduction of 4.287μs over a 1.386km link; a latency reduction of more than 30% relative to conventional single mode fibre. The capacity deployed during the field trial was 6x100Gbps on a single 600Gbps wavelength, and 10x10Gbps on a single 100Gbps wavelength. lyntia’s strategic location in Madrid served as the starting point from which a 1.4km link was deployed to a Digital Realty (Interxion) data centre using AccuCore® HCF fibre optic cable developed by OFS| Furukawa Solutions. In addition, Nokia provided the transmission equipment and field and lab testing.

Telia Lithuania, a Telia Company subsidiary, is deploying Ciena’s WaveLogic 5 Extreme
6500 packet-optical platform powered by
(WL5e) coherent optics to upgrade its countrywide network to support 400G and higher services and deploy the first 800Gbps wavelength service between major cities in Lithuania. With this deployment, Telia Lithuania
WL5e and WaveLogic Ai programmable coherent optics Ciena says the upgrade will mean increased capacity, network reach, and power efficiency; faster wavelength restoration with the 6500’s flexible photonics and intelligent Layer 0 control plane; quicker issue resolution and improved timing distribution for applications requiring highly reliable synchronisation; and simpler service deployment and network operations with Navigator Network Control Suite (Navigator NCS).
says it will be able to deliver more flexible,
higher-capacity, and cost- effective transport services with the resiliency and power efficiency required by 5G, Internet of Things (IoT), and other bandwidth- intensive applications. Telia Lithuania’s new network will also utilise
