New dark fibre installations are expensive to install, often requiring large scale dig works with long lead times. By comparison, our fibre network is already in place, fully tested and supported. By using Wave Division Multiplexing (WDM) we run multiple concurrent optically-isolated circuits over the fibre network between any on-net sites, with terminations as low-cost common 10GBASE-LR (single mode) or 10GBASE-SR (multi-mode) optical presentations. This means new optical wavelength services can be constructed and delivered as quickly as same day and have no hidden charges or administrative overhead to consider. You still benefit from a secure 10Gbps protocol-transparent network, but we take care of all aspects of the end-to-end optical transmission, signal degradation, amplification and optional resilience for you.
