Lantiq Breaks 100 Mbps Barrier for Reverse Powered FTTdp Solution

MUNICH/NEUBIBERG, GERMANY & ANCONA, ITALY - Lantiq, a leading supplier of broadband access and home networking technologies, announced what may be the first commercially available reverse-powered Fiber to the Distribution Point (FTTdp) solution, which uses standard fiber and copper wire broadband technologies to deliver aggregated data rates up to 250 Mbps over 200m twisted-pair copper line lengths. Entirely based on Lantiq’s technology, the ultra-low power FALC-ON GPON and the VINAXV3 VDSL2 chipsets, the solution was jointly developed with Aethra Telecommunications, an access network equipment supplier, and also benefits from reverse power-feeding circuitry. The system sets a new performance benchmark for next generation copper access, supporting triple play broadband services including multiple HDTV channels over IP.

Working from fiber drop points on a neighborhood pole or in a building basement, service providers can provision multiple customer end-points for the enhanced VDSL2 service. The low-power consumption of Lantiq’s broadband access product portfolio makes it possible to reverse power the distribution point from the customer’s premises.

Balanced Fiber and Copper Investment for Advanced Broadband Service
To overcome the high capex requirements for FTTH deployments, Lantiq’s FTTdp solution leverages growing fiber networks and existing copper wire infrastructure to more than double typical copper-based broadband service speeds by moving the optical fiber access point closer to the users.

The combination of Lantiq FALC-ON GPON and VINAX V3 VDSL2 chipset enable system manufacturers to address a variety of deployment scenarios for FTTdp, ranging from single user copper extension of fiber to as many as 16 users being served by a single fiber access point. To maintain the increased copper-performance in multi-user user deployments, Lantiq offers VDSL2 Vectoring to compensate for the additional cross-talk between the users.

According to Hans-Peter Trost, senior marketing manager of Lantiq’s Access Networks Business Unit, “Delivering an aggregate data rate of 200 Mbps or more based on enhanced copper technologies allows service providers to capitalize on the potential of their existing copper access networks.”
