![Convergence is what SARDANA is all about, said Dan
Kelly, Tellabs executive vice president, global products.
By merging the metro and access parts of their networks,
carriers can reduce capital costs.
Using passive products helps to reduce operating costs,
and consolidating locations pares down labor expense,
property tax, maintenance and other office-related expenses.
SARDANA helps with all that.
24 Months to Commercial Launch
Consortium members and European Commission
representatives got their first demo of SARDANA on
October 28, 2010, at the Tellabs facility in Espoo, Finland.
SARDANAs public debut will be February 9-11 at the
FTTH Council Exhibit in Milan, Italy, where consortium
representatives plan to urge the ITU to consider incorporating
SARDANA into the NG-PON2 standard.
Although SARDANA is at least 24 months from commercial
rollout, Tellabs and others are already talking about the
applications it can enable or dramatically improve. HDTV,
UHDV and 3D TV are some potential consumer beneficiaries,
along with holographic telepresence and telemedicine in the
business market.
The challenge [for service providers] is, how do you
deliver more and more services at higher bandwidths and
make the economics work when revenue per user is largely
fixed? Tellabs Kelly said at the Espoo demo.油At Tellabs, we
understand that very well, and it challenges us to innovate and
drive down costs.
Pushing the Envelope
But perhaps the largest, most immediate market opportunity
is mobile backhaul, which is struggling to keep up with about
130,000 TB of traffic per month, according to iGR, a research
firm. By 2014, the monthly load will hit 990,000 TB.
Carriers that use mostly legacy transport protocols
for backhaul such as PDH, ATM over PDH or SONET/
SDH have seen their service charges per connection rise
significantly more in recent years than those using PON or
Ethernet. To rein in their backhaul costs, carriers increasingly
are seeking GPON services.
The focus [of SARDANA] is on pushing the envelope from a
technology perspective: How can we solve bandwidth problems
of capacity, density and reach to deliver high-bandwidth
services in the metro and access networks? Kelly said.
Its a question that just about every major service provider is
asking, putting SARDANA in the right place at the right time.

SARDANAs compatibility with existing GPON
technology is one of its benefits. Others include:
Fewer COs, reducing OpEx.
100 km (62 mile) signal range, more than triple the
reach of todays PONs.
32 times more bandwidth on a single-mode fiber
than todays best PONs provide. SARDANA uses
WDM to drive up to 32 10 Gbps wavelengths down a
fiber where only one currently goes.
This breakthrough delivers 128 times the
bandwidth of G.984 GPON and will enable operators
offer premium-priced, high-bandwidth packages to
large commercial customers. For smaller businesses
and residential customers, SARDANA provides
higher split ratios: up to 1,024 subscribers per PON.
Cheaper, simpler installations. Todays optical
network connections rely on a pair of laser
transmitters for one specific frequency of light to and
from the end-users location. SARDANA replaces
these transmitters, which can cost as much as
$1,000 each, with smaller, colorless ONTs.
Because they have no laser and need no tuning,
these passive ONTs are much less expensive and can
manage all 32 incoming wavelengths. That slashes
inventory requirements.
Greater network resiliency, thanks to a dual-ring
architecture. This also gives PONs greater stability
comparable to Ethernet and legacy SONET platforms.
More bandwidth and network intelligence for smart
mobile backhaul applications. Only optical networks
can keep up with skyrocketing mobile data traffic.
This is the first step
weve had with Tellabs,
and it was perfect.

- 2. Goodbye, dark fiber. Hello, new set of challenges. In the enterprise market, bandwidth-intensive applications have become the norm. Businesses are increasingly using videoconferencing and telepresence to save time and travel costs. Meanwhile, consumers are spending more time online playing games, sharing photos and watching videos and increasingly from wireless devices such as smartphones and tablets. That usage has operators scrambling to strike a delicate balance among capacity, speed, scalability, density, resilience and OpEx. Enter the SARDANA consortium, which is approaching a key milestone toward providing operators with new PON-based solutions to stay ahead of bandwidth demands. Short for Scaled Advanced Ring-based passive Dense Access Network Architecture, SARDANA was founded in 2008 with European Commission sponsorship. Tellabs is the only infrastructure vendor in the consortium, whose other members include France Telecoms Orange unit and several major research universities. SARDANA shakes up PON technology and brings the potential for a new suite of high-quality services to our customers, said Dr. Philippe Chanclou, France Telecom manager of advanced access and home networks. Were very excited to start the field trials in Lannion to demonstrate both the urban and rural scenarios of SARDANA. Passive Convergence SARDANAs goal is to evolve GPON from the ITU-T G.984 standard to the new ITU-T G.987 standard and beyond. G.984 was notable for both its speed 2.5 Gbps downstream and 1.25 Gbps upstream and its support of non-native transport protocols such as ATM, Ethernet and TDM. But G.984s complexity has limited its deployment. Issued in June 2010, G.987 has become the leading candidate for a FTTH GPON specification, largely because of interest from FSAN, a group of major operators and industry experts. FSANs research into 10G GPON produced the technical designs and system requirements for two classes of service: XG-PON1, which meets the G.987 standard by providing 10 Gbps downstream and 2.5 Gbps up, and XG-PON2, featuring 10 Gbps symmetrical. In response, the SARDANA consortium came together in 2008 to develop a structure for next-generation PON networks. SARDANA merges the access part of todays networks with their core or metro ring, where multiservice Layer 2 and 3 functionalities now reside. The merger extends these capabilities out to locations that currently rely on a CO, including cellular base stations, homes, small businesses and rural areas.
