Optical Wavelengths FAQs

  • How do Optical Wavelengths differ from Dark Fibre?

    Optical Wavelengths is a managed service that provides high-capacity, low latency connectivity over dedicated channels on an existing fibre network. In contrast, Dark Fibre, also known as unlit fibre, is installed but unused fibre that you must equip and operate yourself to create and run the network.

  • When should you choose Optical Wavelengths over Business Ethernet?

    Business Ethernet is ideal for connecting sites or network-to-network interconnects (NNI) at bandwidths up to 100Gbps. Optical Wavelength services deliver dedicated, uncontended performance up to 400Gbps+, making them ideal for data centre interconnects, core networks and other data-intensive workloads.

  • Where are Optical Wavelength services available in the UK?

    Optical Wavelengths is available across our extensive UK-wide network, connecting key cities, data centres and exchanges nationwide. We also support a range of access methods across the UK, including Openreach and other third-party tails.

  • How easy is it to scale Optical Wavelengths from 10Gbps to 400Gbps?

    Scaling Optical Wavelengths is typically straightforward, as capacity can be increased by provisioning additional wavelengths on the same fibre. In many cases, this avoids the need for new fibre builds, allowing you to scale to 400Gbps with minimal disruption.

  • What resilience and diversity options are available with Optical Wavelengths?

    Optical Wavelength services can be designed with diverse routing and dual fibre paths, allowing automatic failover across our resilient core network. If one path fails, traffic can be rerouted instantly to keep you connected.

  • What are the typical lead times for deploying optical connectivity?

    Deploying business‑grade optical connectivity typically takes 45-90 working days, depending on location, existing fibre availability and any required wayleaves or civil works. With Neos Networks’ rapid activation, you can also get up to 100Gbps Optical Wavelengths deployed in select UK data centres and exchanges in as little as 10 days.

  • What factors influence the cost of optical connectivity?

    The cost of optical connectivity depends on factors such as bandwidth, route distance, site location and the level of resilience or diversity required. It can also be influenced by whether new fibre needs to be deployed or existing infrastructure can be used. With a managed service like Optical Wavelengths, you can minimise upfront costs and benefit from predictable monthly pricing.
