– ‘Reversed-Powered’ from the Residence
– Chipsets Available Now
– Up to 16 Users per Fiber
Telcos have gone from few choices for increasing their
broadband speeds to a cornucopia of technologies.
Chipmaker Lantiq, which specializes in broadband access and
home networking technologies, said this week it has worked
with telecom gear maker Aethra Telecommunications to develop
broadband technology called reverse powered Fiber to the
Distribution Point (FTTdp) that will allow telcos to offer
speeds of up to 250 Mbps over 200 meter (yards) long twisted-
pair copper. It operates over existing standard fiber and
copper wire broadband networks.
It’s capable, it said, of multiple HD TV channels
simultaneously over IP, which must also mean multiple channels
of OTT HD videos simultaneously.
It works from fiber drop points on a neighborhood pole or in a
building basement. Lantiq said it’s entirely based on Lantiq
technology. Its ultra-low power FALCT-ON GPON and the VINAXTV3
VDSL2 chipsets benefit from a patent-pending reverse power
It can save telcos the enormous cost and effort of deploying
Unlike other high-speed copper wire technologies G.Fast and
DSL Rings, Lantiq’s FTTdp chipsets are available now for
equipment makers. That means it’s probably already working
with broadband equipment makers on getting telcos to check out
Lantiq said its technology’s “very low-power consumption makes
it possible to reverse power the distribution point from the
customer’s premise” rather than from a central office.
Lantiq and Aethra will demonstrate the FTTdp solution at
Broadband World Forum, October 16-18 in Amsterdam. It’ll show
that FTTdp is fully reverse powered, based on a customer
premise power injector adaptor developed by Aethra. It said
the ultra-low power consumption of the Lantiq solution and
Aethra’s long-term experience with low-power consumption
hardware designs ensure that the distribution point can be
reverse powered by only a single user.
The combined chipset will enable system makers to address
scenarios from a single user copper extension of fiber to as
many as 16 users. To maintain the increased copper-performance
in multi-user deployments, Lantiq offers VDSL2 Vectoring to
compensate for the additional cross-talk between the users.
Hans-Peter Trost, senior marketing manager of Lantiq’s access
networks business unit, said the 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. He called it “a new benchmark
for copper-based broadband access services.”
Aethra develops, manufactures and markets network access
devices and carrier solutions, including VDSL2/ADSL2+ router
and VoIP gateways and SHDSL Ethernet Access Devices.
Antonino Paris, head of research and development at Aethra,
said, “Fiber-to-the-home (FTTH) has suffered from a number of
stop and go deployments, especially in Western Europe, due to
inherent difficulties in cabling fiber inside buildings.
Fiber-to-the-box (FTTB) has also been limited by all the
issues related to powering MDx equipment and buildings’
basements.” He said Aethra and Lantiq worked together “to
overcome all these constraints in a simple and effective way.
He said, “High speed Internet access at 100 Mbps symmetric
over copper wires is now possible at a fraction of complexity
and costs of FTTx.”
