EPON ONU from Cortina supports IPv4/IPv6
co-existence
Cortina Systems, Inc. has announced its 4th generation
EPON ONU, CS803x, which supports embedded CPU and a flexible
memory configuration for common ONU types. The CS803x is
compliant with SIEPON's power saving feature and supports
the new IEEE Energy Efficient Ethernet standard.
"Carriers are implementing PON as a way to deliver
fast optical connections to support end users demand for
both high speed bandwidth and advance services," said
Rick Li, Vice President Marketing, Cortina Systems. "Not
only does the CS803x reduce BOM costs by embedding the memory,
it supports IPv4/IPv6 co-existence for seamless migration
from IPv4 to advanced IPv6 services and a powerful processor
for VoIP service. The CS803x provides a solution for the
FTTx industry with leading benchmark of performance over
power and cost."
"The CS803x from Cortina is one of the first high-performance
EPON chips to support the IEEE's SIEPON standard, which
aims to facilitate interoperability," said Jeff Heynen,
Directing Analyst, Broadband Access, Infonetics. "The
CS803x is already one of the most versatile EPON chips on
the market, with applications ranging from low-end ONT to
multi-play residential gateways. Adding SIEPON support increases
its versatility by guaranteeing interoperability."
The CS803x, a low power single chip EPON ONU with a 500MHz
CPU and multiple embedded memory options, has a flexible
architecture that allows it to be used as a SFU (Single
Family Unit), IP Voice and Video, HGU (Home Gateway Unit),
and MDU (Multi-dwelling Unit). It features a VoIP interface
that can support up to 4 instants of conversation. For mobile
backhaul and business connectivity applications, the CS803x
supports 1PPS/ToD timing synchronization based on China
Telecom V2.1 EPON Specification and IEEE 802.1AS. The rich
feature set and the low BOM cost make the chip an ideal
candidate for a single platform solution for a one-port
ONU to a full featured triple play home gateway, says Cortina.
"With energy costs skyrocketing, everyone is looking
for ways to manage their power consumption, especially power
companies," comments Li. "Cortina's CS803x family
has integrated UART, which enables utility companies to
manage power grids by collecting power utilization from
the power meter and sending it through the PON network to
the controlling center. Power companies in China expect
to save billions of dollars in efficiency by implementing
this function and routing power to the critical portion
of its grid more efficiently."
