Lightspan SX/DX

Next-generation programmable micronodes

Lightspan SX and DX are second generation distribution point units (DPUs) designed to complement fiber deployments and provide fiber-like services to customers in multi-dwelling unit (MDU) buildings.

Lightspan SX DPUs are sealed units for harsh outside plant environments or for deployment in MDUs without a dedicated location for telecommunications equipment. Rack mountable Lightspan DX DPUs are ideal for MDUs where rack space is available. As part of the Nokia Lightspan family of access nodes, Lightspan SX and DX micronodes support open standard management models with NETCONF/YANG.  

With Zero Touch Provisioning, operators can increase the speed of deployment by 50% over traditional approaches. In cases where a reverse power feed (RPF) is required, persistent management of all network elements at once - whether online or offline - is supported.
