Universality and Sustainability

The compact Iskratel Lumia OLTs are world’s first “amphibious” OLTs, able to operate in conventional mode or in virtualised SDA (Software-Defined Access) environment. Their unique dual nature lets operators virtualise and cloudify the network without hardware replacement, allowing them to skip an entire investment cycle while introducing software-defined, next-generation broadband access.


  • Two characters: conventional and virtualised.
  • One amphibious box.
  • Zero hardware upgrade.


Seamless Transformation

Unlike other OLTs in the market, Iskratel Lumia OLTs can host a distributed, virtualised BNG (Border Network Gateway) to take care of automated provisioning and accounting for the services you provide to customers, and cut the costs of your infrastructure for years to come.

With embedded vBNG, Iskratel Lumia OLTs make the perfect choice for anyone who needs a flexible, extensible and future-proof solution. As Iskratel Lumia Edge OLTs, these top-of-the-line programmable OLTs protect the existing investments and make production life simpler while keeping up with future demands.
