Why choose Spectrum?

  • Scalability and Control

    You have full control of Dark Fibre, without the capital cost or operational overhead of deploying long-haul dark fibre or build-out of a photonic layer

  • Network Diversity

    We understand the importance of network route diversity, so we work with you to design a diverse path from other routes you currently use, or provide a clear secondary diverse path

  • Future-proofed

    Colt Spectrum provides support for various different modulation schemes, opening up the possibility of delivering future upgrades as technology changes

  • Ownership economics

    Leverage existing DWDM assets, and providing a migration path towards or away from Dark Fibre as required

  • Simplicity

    Add, remove or reconfigure up to 100G wavelengths to meet the demands of your business

  • Unprecedented reach

    We're connected to 29,000+ buildings and 900+ data centres in Europe, Asia and America, more than any other carrier

Colt Spectrum explained

  • Colt Spectrum is a hyperscale connectivity product which uses Colt’s dedicated network at the photonic layer to provide services over long-haul distances. Customer’s use their own optical transponder equipment to connect to the Colt IQ Network in blocks of 50GHz optical channels – with the advantage that Colt manages the underlying line system

    Alternatively, Dark Fibre can be leased to enable customer to meet capacities of 2Tb+ but this requires increased equipment and networking experience to light, monitor and manage the service.

  • Spectrum is available based on 50Ghz channels, and provides access to an optical core network based on DWDM technology consisting of fibre, ROADM nodes and amplification infrastructure – collectively known as a photonic layer. The photonic layer connects key service locations such as data centres and Colt network nodes.

    The Colt platform supports transport of coherent wavelengths, based on a modulation scheme of your choice: QPSK, 8QAM or 16QAM. Other modulation schemes may be supported, please get in touch to discuss your requirements in more detail.

  • Yes! Our state of the art optical foundation on the Colt IQ Network enables delivery of 100GB or 400GB connections as a service to our customers.
