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.
