What are Alien Wavelengths?

Alien wavelengths are wavelengths that are added to existing OTN or DWDM network infrastructure. This is important when a network capacity has been exhausted and the backbone needs to scale to support growth in demand for bandwidth. A sudden surge in network requirement for bandwidth may occur without warning, and the network needs to grow to support capacity needs.

Alien wavelengths are added by using muxponders or transponders that are vendor-agnostic to third party Ethernet and Fibre Channel switches on the client side, and mapping them to higher capacity OTN uplink. This drives more capacity cost-effectively over any existing OTN or DWDM network infrastructure.

They enable to connect high capacity 100G/200G/400G wavelengths over existing third party vendor DWDM/OTN network, by aggregating a mix of Ethernet, Fibre Channel, and OTU2-4 services, into 100G/200G/400G DWDM wavelengths. This ads capacity to the existing network without requiring any changes to the backbone infrastructure, which would otherwise require a financial investment and time.

They can also be used to increase the security of dedicated circuits running over the optical network backbone, by adding Layer-1 AES-256 encryption over all the transported data.

Alien wavelengths enable fast upgrade of network capacity when it is needed and solve the vendor lock-in. This is especially important when there is a shortage in components and their delivery times are longer than usual.

Alien wavelengths also enable to add encryption to the network either by adding wavelengths with Layer-1 encryption, or as an add—on to the existing backbone, without any changes to the network. This enables carriers to offer secured infrastructure to customers that demand high level of confidentiality.
