Aurora Networks Introduces Dual Channel Digital Return Transceivers and
Receivers
Products Double Available Upstream Bandwidth per User for Significant
Cost Savings
Santa Clara, CA. — November 18, 2002 — Aurora Networks, a leading
developer of advanced optical transport systems for broadband networks, today introduces
a line of dual channel digital return transceivers and receivers. These dual channel/dual
segment or "2-fer" devices allow twice the amount of information to be transmitted
over the same fiber cable, effectively doubling the available bandwidth per user in the
upstream path.
Ideally suited for use in hybrid fiber/coax (HFC) and fiber deep architectures,
Aurora’s "2-fer" digital reverse product line supports cost-effective growth in
high-speed data and telephony penetrations by increasing the useable reverse bandwidth.
This efficiency is accomplished by putting twice as much data onto the same fiber through
two discrete return channels of upstream data from the optical node. Each channel is
received independently by the dual channel receiver and routed through discrete RF return
outputs. This operation provides fiber availability for additional return path bandwidth
and rack space for additional return path receivers.
"Aurora’s '2-fer' digital reverse product line utilizes proprietary
technology to effectively double the amount of bandwidth available in the return path,"
said John Dahlquist, Vice President of Marketing for Aurora Networks. "By eliminating
the need to deploy new fiber to support node segmentation to meet the throughput needs of
additional return path traffic, Aurora’s new digital return products save cable operators
time and money."
"Aurora’s digital return technology is changing the way broadband cable
operators deploy and scale their networks," said Ron Wolfe, Senior Product Manager,
CATV for Aurora Networks. "Our digital return products enable existing optical nodes
to be fully segmented, with each RF input port treated as a discrete network, maximizing
the available bandwidth per user, while at the same time conserving the cable operators'
investment in the fiber network."
The Aurora dual channel digital return product line includes:
- DT4200 Series Digital Transceiver modules for Aurora’s NC4000 series optical nodes.
This product is scheduled for shipment in January 2003. All Aurora DT4000 series
transceivers incorporate status monitoring of the node within the digital return
channel, eliminating the added cost of status monitoring transponders.
- DT5200 Series Digital Transceiver modules for Motorola’s Starline® series optical
nodes. This product is available now. Status monitoring of the DT5200 transceiver
series is provided within the digital return channel.
- DR3021 Digital Receivers for the Aurora CH3000 universal chassis located at the hub or
headend. Receivers provide redundancy capabilities through the use of an optional A/B
switch.
Aurora 4000 Series Node
Optimized for high-bandwidth capacity in both the forward and return paths, the Aurora
4000 series node is segmentable to serve four independent return service areas and four
independent forward service areas. This highly flexible segmentation capability allows
the network to be scaled for the balancing of forward and reverse traffic loads to meet
the operator’s requirements.
For applications such as fiber deep or passive HFC, the Aurora 4000 series
node can be configured in a concatenated or "daisy-chained" configuration to
allow multiple nodes to share a common digital return channel. Conversely, in
applications where node service areas are larger, such as traditional HFC, individual
nodes can be segmented into multiple return channels. The use of node-based dense wave
division multiplexing (DWDM) digital transponders provides further return path fiber
savings.
