Alien wavelengths are wavelengths that are vendor-agnostic to third-party Ethernet and Fibre Channel switches and can be added to OTN/DWDM networks to drive more capacity without the need to replace existing backbone infrastructure. The solution answers the demand for increased transport capacity and releasing bottlenecks in any network. Alien wavelengths also enhance business opportunities by enabling the delivery of services that may not be supported by existing infrastructure (e.g. Fibre Channel and video), and Layer-1 encryption. They can also offer encrypted services over existing unsecured network for dedicated customers or applications, and enable encrypted wavelength services over existing networks.
