The GPON/VDSL DPU terminates a carrier’s fiber line near subscriber homes, and then extends 8 VDSL lines into customer premises. Based on the renowned Lantiq FALC ON GPON SoC and the new Lantiq VINAX dp8 VDSL2 transceiver, this innovative system integrates all required network processing functions for flow control with advanced impulse noise protection (G.INP) and solid quality of service (QoS) features. The reference design also includes an advanced reverse power extractor, ensuring balanced power sharing among up to 8 individual user lines.

By eliminating the need for costly termination of fiber lines inside each customer premise, FTTdp is the most economical network topology available to many carriers that have invested in fiber distribution lines. On short copper loops in a hybrid FTTdp network, VDSL2 technology provides fiber-like rates up to 300 Mbps.

Furthermore, hybrid fiber/copper DPUs can be reverse powered from the subscriber home and do not require a power source. Additionally, the low port density of DPUs makes FTTdp substantially less complex and much easier to deploy and manage than conventional DSLAMs and MDUs.

Features:

－ Up to 8 VDSL lines with up to 300 Mbps aggregated data rate per line at 100 meter range from the DPU

－ Robust architecture, with data rates not impacted by CPU load or in-band control

－ Minimal footprint of the complete solution; with the integration of network processing functions and a new reverse power extractor, the reference design fits in a 16 x 16 cm box

－ Carrier-grade feature set and future proof roadmap, based on field proven GPON and VDSL platforms with millions of lines installed worldwide
