Calypte Long Haul

Calypte Long Haul is a cost-effective solution that gives you rate-monitored connectivity between predefined sites along the long-haul route from a submarine-cable landing station to a metro.

If you don’t need unlimited speed all the time, Calypte lets you choose a burstable data rate while still giving you the benefit of dark fibre. There is no hard limit on the bandwidth – your traffic can exceed the chosen data rate for short periods – and you can permanently upgrade or downgrade your bandwidth. Together with Tachyon, Peregrine, and Helios, it enables you to design and build your network in the most cost-effective way.


Calypte Long Haul enables you to manage your costs for long-haul connectivity more efficiently by giving you the ability to scale as your needs increase. Connect between predefined repeater sites and along predefined routes with a rate-monitored, burstable service.
