Iskratel Lumia T14 – High-density shelf-based OLT
Iskratel Lumia T6 – World's fastest shelf-based PON OLT

High-capacity Iskratel Lumia OLTs are scalable, high-performance fibre OLTs that connect end users over a variety of PON technologies from a single, cost-effective platform.

Iskratel Lumia OLTs fit all deployment densities, from high-density urban to low-density rural areas, while various shelf options and interfaces address every use case in the fibre-access network.

The outstanding switching, backplane and uplink capacities make Iskratel Lumia OLTs ideal to host all present and future PON technologies, from GPON and XGS-PON to 50G- and 100GPON.

The super-long lifespan is further facilitated by the dual nature of Iskratel Lumia OLTs: sup­porting conventional and virtualised operation on the same hardware, they allow operators to skip entire investment cycles.

Fully compliant with the Code of Conduct on Energy Consumption of Broadband Equipment, the energy-saving Iskratel Lumia OLTs help operators cut energy bills and reduce the impact on the environment.

Iskratel Lumia T14 – High-density shelf-based OLT

Iskratel Lumia T14 is a 14-slot, multi-terabit OLT with terabit-capable backplane. It provides flexible port configuration with XGS-PON, GPON, Combo PON, or 25G/50GPON subscriber blades, while its scalable density makes it ideal for deployment in central offices, street cabinets or buildings.

Fully equipped with Combo PON subscriber blades, Iskratel Lumia T14 provides FTTH connectivity to more than 50,000 users over 208/192 ports of a single OLT.

With 400 Gbps per subscriber blade and switching capacity of 3.4 Tbps, Iskratel Lumia is able to host present and future PON technologies in a super-scalable, high-density OLT.

Iskratel Lumia T6 – World's fastest shelf-based OLT

Iskratel Lumia T6 is a 6-slot, multi-terabit OLT that supports 800 Gbps per subscriber blade. On top of 3.4 Tbps switching capacity, the uplink capacity can be boosted up to staggering 1.4 Tbps, which makes Iskratel Lumia T6 the world's fastest PON OLT.

Its outstanding capacity makes Iskratel Lumia T6 easily extendable from currently supported 10-gigabit PON (Combo and XGS-PON) to 50GPON and 100GPON in the coming future. At present, Iskratel Lumia T6 can serve more than 20,000 users from its 80/64 Combo PON ports.

The super-long lifespan across a range PON technologies guarantee full safety of investment.
