GPON networks become economically viable
Passive Optical Network/CWDM
The Industry’s First RFoG-Ethernet Access Network
Upgrading a network with fiber-to-the-home is famously expensive – witness the more
than $18 billion Verizon has earmarked for its FiOS upgrade – but FTTH is acknowledged
to be an economically feasible option in new builds.
There’s also a solid case to be made that recommends FTTH for Tier II and Tier III
service providers, both cable and telco.
Furthermore, with costs coming down for gigabit passive optical network (GPON)
equipment, fiber vendors are trying to make the case that upgrades to GPON networking
can be feasible for even the largest MSOs.

Corning Cable Systems’ passive optical solutions provide total connectivity from the headend to the customer premises for advanced MSO architectures. Implementing Corning Cable Systems’ passive optical network (PON) and/or course wavelength division multiplexing (CWDM) designs
results in increased performance and reduced costs. Preconnectorized solutions offer increased performance and reliability through the use of
factory-installed and -tested connectivity. Preconnectorized assemblies also reduce deployment time and labor required, while increasing managed
accessibility of maintenance resources to the plant. Costs are further reduced through initial construction labor, faster maintenance and lower ongoing operational expenditures. Whether deploying fiber-to-the-home, wireless backhaul or fiber-to-the business networks, Corning Cable Systems’
preconnectorized solutions are the new standard for today’s advanced communication networks.

Aurora Networks’ Node PON
for Cable Architectures
Many of the world’s leading MSOs have been building their networks using Aurora’s NC4000 series nodes. With
Aurora’s latest service expansion module, the GE4132M Node PON, operators can dramatically increase their service
capacity. Aurora’s Node PON module enables delivery of an additional 1000 Mbps of service capacity to each of their
node service areas. Aurora’s Node PON solution allows operators to preserve topologies with redundant optical paths,
maintaining enhanced network reliability and providing a significant advantage over traditional PON architectures. The
Node PON solution complements Aurora’s other Access Network Solutions such as FTTP, Fiber on Demand and BitCoax.

This figure illustrates a PON at a high level. To the left is the point of signal origination, called a headend in the cable
TV industry, and a central office (CO) in the telephone industry. The PON is considered to start with the Optical Line
Terminal (OLT), and to end at the home with the Optical Network Terminal (ONT). The OLT handles the PON protocol
conversion and, in the case of Enablence’s Trident7, performs data aggregation. The broadcast video portion of the
OLT can be considered to be the optical transmitter, sometimes called the Video Optical Line Terminal (VOLT). Other
people take the optical transmitter to be just a normal part of the video headend and don’t consider it to be part of the
OLT. The broadcast video chain will also normally include optical amplifiers, (usually EDFAs – erbium doped fiber amplifiers), not shown.
The Enablence ONT, at the subscriber’s home, contains optical/electrical signal conversion, and includes RF signal
buffering and AGC, conversion of data to 10/100BASE-T on two ports, and voice conversion to POTS. Sometimes the
term Optical Network Unit (ONU) will be used instead of ONT, if less functionality is included in the product.
In between the OLT and ONT is the network itself, called the Optical Distribution Network (ODN). This term excludes
the OLT and the ONT. Only passive splitting exists in the ODN, yielding a highly reliable, scalable, and low maintenance
network. No active circuitry exists in the ODN, although Enablence does offer a temperature hardened Trident7 Compact OLT (COLT) that may be located outside of the CO, interconnected to the CO through other fibers.

Cisco Prisma D-PON Solution (MSO FTTH)
•
•
Cisco’s Prisma DOCSIS PON (D-PON) products are a
fiber-to-the-home (FTTH) solution specifically designed for
DOCSIS-based service providers.
The D-PON solution provides an MSO with the benefits of a
PON while maintaining and leveraging the existing HFC
back-office systems, such as broadcast video, narrowcast
video, switched digital video, VOD, DOCSIS data, DOCSIS
VOIP and VDOC.
The D-PON solution supports 78 analog channels and 75
QAMs and will reach a distance of 20kms+, through a 32-way
optical splitter, with full DOCSIS 3.0 upstream loading
(four 64 QAM channels).
Service group sizes can be reduced in the Headend from 512
(16 PONs) to 256 (8 PONs) to 128 (four PONs) without
having to roll a truck to modify the outside plant – the D-PON
solution is truly a future proof architecture, today and tomorrow.
