This approach lets cable operators who may be seeking to capture fiber-to-the-home (FTTH) revenue to begin almost immediate delivery of ultra high-speed data services over optical fiber on an individual subscriber basis. While minimizing capital and operating expenses, the solution maximizes
revenue potential by leveraging operators’ existing hybrid fiber-coax (HFC) architectures. Operators can
capitalize on new revenue streams by deploying dedicated access, optical Ethernet circuits — up to 100 Mbps
symmetrically — more rapidly and less expensively than their RBOC competitors and, at the same time, pinpoint
deployment whenever and wherever customers demand it.
The few items of equipment required to implement this powerful architecture, which
supports up to 160 optical fast Ethernet circuits per fiber pair as well as legacy node traffic, includes
the DS4004U Optical Ethernet Concentrator for installation in NC4000 series optical nodes, the NI3030E Network
Interface module for installation at the headend, standards-based customer premises equipment such as the
MC1201U or MC1301P Media Converter, and (when appropriate) the hardened and strand-mountable PG1210A Power
Gateway with power over Ethernet (PoE) support for wireless backhaul applications.

The 5G Node™ can deliver a total 4 Gbps of data throughput as well as
RF video with a 1 GHz RF passband. With its patent-pending design, engineered to ensure compatibility
with cable operators’ existing network infrastructures (including the use of existing headend and
subscriber equipment for video delivery), this configuration of the NC4000 series node, fully
populated with four PON Modules, can achieve a combined data throughput rate of 4 Gbps to service up
to 256 homes passed. Coupled with its support for a full 1 GHz RF passband on a 1550nm transport, this
revolutionary Fiber-to-the-Premise ''5G Node'' reaches distances up to 80 kilometers and can be serviced
with a single fiber or two fibers for optical path protection. 
Each of the new GE4132M PON Modules that are used in this node enable
100 times more capacity than conventional data delivery methods, and up to four of these modules can
be installed in the 5G Node. The GE4132M PON Module can also be used in any standard NC4000 series node
or Virtual Hub and is compatible with HFC, Fiber Deep, Fiber on Demand™, and FTTP architectures.
As a pioneer in digital return with built-in node monitoring and embedded Ethernet, Aurora’s development
of a PON Module for cable is a natural step in extending the bandwidth lead against telcos. 
Aurora's FTTH Hub Platform is designed to work seamlessly within
existing Hybrid Fiber Coax (HFC) networks and is compatible with existing headend and customer
premises equipment. A typical FTTH Hub configuration, which supports industry standard FTTH
architectures, consists of a high-power (+24 dBm) EDFA and an 8-way splitter to distribute a
1550nm downstream signal to eight output fibers. A forward/return optical diplexer separates the
eight downstream 1550nm signals from eight upstream 1310nm signals. The eight upstream 1310nm
signals are routed to eight upstream receivers, the outputs of which are combined into a single
RF signal which is then digitized and transmitted upstream at 2.125 Gbps using Aurora’s patented
digital reverse technology transceiver. The typical configuration utilizes one of Aurora's ''2-fer''
Digital Transceivers (model DT4230N) that supports 128 homes passed for each of two return paths.
