Lightspan DF Fiber Access Nodes

Small access nodes for multi-Gigabit broadband

A new generation of fiber access solutions for distributed fiber deployments.

Multi-Gigabit networks fulfill the potential of our connected future, open up many possibilities for new services, and give operators reliable value for years to come.

The Nokia Lightspan DF is a family of optical line terminals (OLT) that gives you new flexibility in your fiber deployments and helps optimize the business case. With the Nokia OLT fiber portfolio, you can cost-efficiently address all types of deployments: high volume, high user density with Lightspan FX and Lightspan MF; lower user density with Lightspan DF and Lightspan SF. This means you can connect users with multi-Gigabit services no matter where they are.

The Lightspan DF nodes are mini-OLTs that support GPON, XGS-PON and 25G PON in a distributed or disaggregated access network architecture. With flexible combinations of PON configurations and stackable deployment options, Lightspan DF OLTs enable cost-efficient network evolution today and in the future. As members of the Lightspan family, they fully support SDAN (software-defined access networking) for streamlined operations and reduced OPEX.
