Optical Spectrum Access (OSA)

OSA is a flexible, cost-effective way to move very large amounts of data between two sites. A dedicated optical fibre link means a secure, always-on connection. 

How it works

OSA relies on a signalling technique called wavelength division multiplexing (WDM). This is an efficient way to send more than one signal along an optical bearer (the fibre optic cables and equipment along the signal’s path).

Multiplexing gives each optical signal its own wavelength (or frequency), then combines these signals to send them to their destination at the same time. At the end of the path, the networking equipment separates out these wavelengths – or de-multiplexes them – before processing the data.

We can then configure these different wavelengths to support different protocols and carry different data – or even give you direct access to the fibres to configure yourself with OSA filter connect. 

Use it to offer premium services to your customers from cloud applications to next-gen data centres and ultra-fast file transfers. 

OSA 100G Single

OSA 100G Singles provides businesses with a dedicated, secure and always-on fibre link, at a ‘game changing’ price point.  With a starting wholesale price of £863 per month including connection and annual rental.

The service also features significantly ‘slimmed down’ product options to help create a solution that’s easier to understand, consume and manage.

OSA Filter Connect

OSA Filter Connect gives you direct access to the optical path. That means you can connect your own dense wavelength division multiplexing (DWDM) equipment using the spare filter ports. We need to manage at least one wavelength (though we can do more if you need).

This gives you the best of both worlds: we’ll look after the fibre and manage the wavelengths, and you can develop your own services over the spare channels.

There are some restrictions: you can’t use OSA to build, extend or replicate core networks.

Here are some of the reasons why OSA could work for you: 

• fast set-up – our shortest DWDM lead times
• low risk – we offer an entry-level 1U chassis option with a minimal footprint
• customisable – multiple wavelength, chassis and interface options
• dedicated fibre – low latency, and great for data security and service quality
• expert design – planned to your brief and built with Adtran optical networking expertise
• direct fibre access – tailor and manage how you use the optical path with Filter Connect.
