OverviewFTTx ignites a technology shift from the existing copper cabling systems to fiber, which provides almost unlimited transmission rates. Since fiber networking is a proven broadband technology with virtually no limits, it can be expanded any time to meet bandwidth demand of individual customers over the upcoming years. In this FTTx solution guide, ZyXEL provides solutions for all possible forms of fiber infrastructure and ways to leverage existing DSL deployments for the best synergy.

■ FTTx Creates Business Opportunities

FTTx operation in Next Generation Access (NGA) services will

increase ARPUs reliably by +30% above DSL (Yankee Group,

2008). Additionally, FTTx revenue is increasing thanks to the

cooperation with the entertainment industry where high-

quality online services and content are offered, while the

ultra-high bandwidth provided by FTTx also enables video

conferencing and unified communications services for both

commercial and residential users.

Driving Force of FTTx: High-definition IPTV is one of the key

drivers of FTTx, with which 2+ simultaneous HD streams for

multi-room IPTV services will become the major trend in

the upcoming years. Green environment issues are another

driving force because fiber deployment produces less CO2

than copper wires.

Market TrendBenefits of FTTx■ Blazing-fast Services for an Edge

The FTTx solution is the most popular next-generation

broadband access solution adopted by leading service

providers worldwide. It is offering not only symmetric

100Mbps or 1000Mbps bandwidth to homes, but also high-

definition IPTV, video-on-demand, music-on-demand,

home monitoring and control, high-resolution 3D format

video and even more premium triple-play services. Service

providers can choose the best FTTx solution to retain

existing subscribers and win more under future extension,

market competition and economic considerations.

How ZyXEL Can Help You?

ZyXEL has developed complete broadband technologies

for COE and CPE product lines, and it’s a trouble-free and

cost-effective approach to deploy the next-generation fiber

solutions of FTTN, FTTC, FTTB, FTTP and FTTH by means of

AON or PON fiber access technologies. Please refer to the

figure of ZyXEL End-to-end FTTx Solution including MSAN,

DSLAM, Carrier Ethernet and PON in access CO site, as well

as the versatile customer edge premises on the subscriber

site. (Figure C)

Background of AON and PON: ■ AON (Active Optical Network, Active Fiber or Active

Ethernet)

Active fiber is a dedicated medium in which each end user

is allowed independent access. Each end user has a home

gateway with active fiber directly connected to the carrier

Ethernet switch in the central office or street cabinet by a

direct fiber. Between the central office and the end user,

there can also be an aggregation Ethernet router if needed.

■ PON (Passive Optical Network)

PON is a shared medium in which a fiber is “passively” split

into many end user connections. The term “passive” refers

only to the optical splitter, which does not require external

electrical power to function. Each end user has one GEPON

ONU (Optical Network Unit) or GPON ONT (Optical Network

Terminal) while the fiber terminates at a central office

in an OLT (Optical Line Terminal) that requires electrical

power. Between the OLT and the ONU/ONT may be one or

two stages of passive splitters that split the connection to

multiple end points.

End-to-end, Point-to-point Active Fiber Solution

“Open Access Model” is an emerging operator-neutral

business model to offer ICT infrastructure and network

services suitable for FTTx solutions; the potential customers

include Telco operators, service providers, MSOs, content

providers and users from government, banking, education,

military, police, broadcasting as well as utility companies

or agencies. The P2P active fiber is the best solution to

meet all the requirements of aforementioned customers.

The P2P active fiber solution has some advantages as well:

such as easy management, matured standard technology,

dedicated bandwidth offering and the future-proof access

architecture.

ZyXEL offers a complete end-to-end Gigabit and 100

Mbps active fiber solution; all active fiber CPE products

Figure 1-1: Roles in Open Access Network

Figure 1-2: Roles in Open Access Network

Figure 1-3: Equipment Owner of Telco Operators and Multi-Site Users

support both SNMP and TR069/TR104 to meet network

management demands from various customers. Please refer

to the following application figures and supported product

tables for more details.

The Figure 1-1 describes the roles of open access model,

in which municipalities or utility companies play the role

as the infrastructure owner, while Telcos, MSOs and service

providers play the role of network operators or service

providers to offer related services to residential or SMB

users. Multi-site users will be the enterprise subscriber to

subscribe the Internet infrastructure, as an extension to the

intranet, from network operators or service providers.

Telcos can rent the active fiber pipe, deploy their own COE

and CPE, and then offer high-quality triple-play services

to subscribers. Please refer to the figure 1-2 that indicates

the FTTx applications through open access model and the

figure 1-3 that indicates the equipment owner.

For MSO operators, please refer to the figure 1-2. Since

active fiber supports RF-over-Glass (RFoG), MSO operators

can transform their CATV over active fiber pipe and offer

high-quality triple-play services to their subscribers. For

multi-site users, please refer to the figure 1-3; the users will

deploy their own security routers on the extended intranet

through open access network services.

Benefits: ■ Flexible bandwidth offering from 100/100 Mbps to

Gigabit/Gigabit throughput per subscriber■ Breakthrough business model with matured and

proven Ethernet technologies■ Offer RF-over-Glass technology to provide high-

GEPON is the most widely deployed and matured technology

with advantages like easy management, cost effectiveness

and easy sharing. It is a good solution for FTTH applications.

MSOs can use its RFoG (RF-over-Glass) feature as their next-

generation cable PON to upgrade broadband bandwidth

and expand customer base.

Today’s service providers are demanding larger bandwidth

for subscribers to offer HDTV, MoD, VoIP and online gaming

services. The options for service providers to deliver decent

bandwidth are still dependent to the mixed network

architecture, and the demands are being met by the deeper

penetration of fiber optics in the Access Networks.

Although CATV companies now provide over 100 Mbps

service with DOCIS 3.0 to compete with ILEC/CLEC, they are

now considering fiber deployment for providing services

such as triple-play services (voice, data and cable video;

please refer to the following application figure-2). Besides,

the HFC plant brings reliability/availability, powering and

potentially disruptive upgrades into question; on the

contrary, fiber has better reliability and PON has few plant

electronics, use less power and are easier to upgrade.

On the CO (Central Office) side, video signal received from

satellite to video head-end goes through amplifiers to

amplify the signal. A WDM combines the wavelength of

broadcasting video (1550 nm) and IP data (1490 nm) to

transmit through the fiber of outside plant to home users.

The WDM on the user side is to divide the wavelength to

two different wavelengths (1550 nm, 1490 nm) to different

transceivers. V-ONU demodulates 1550 nm signal for

broadcasting video programs. GEPON-ONU demodulates

1490 nm for IP data transmission.

The demand for greater bandwidth for Internet never stops

rising. No matter it’s for multimedia applications or a more

cost-effective means for enterprise connectivity, vendors

are not only expanding their lineup with new models, they

are adding value with new features as well. Today, ADSL2+

is the mainstream xDSL modem technology and the most

deployed one in the world.

ADSL2+ provides Internet access via standard copper

phone lines while it still allows users to make phone calls

over the same line. ADSL2+ boosts this to 24 Mbps over the

same phone lines and connection distance of up to 1,828.8

meters.

ZyXEL targets the MSAN and ADSL2/2+ CPE functionalities

at improving performance, interoperability and supports

to new applications, services and deployment scenarios.

Among the changes are improvements in data rate and

reach performance, rate adaptation, diagnostics and stand-

by mode, etc.

Benefits: ■ Maximize the performance of copper wire with

higher speed and longer coverage distance■ Provides 2-pair, 4-pair and 8-pair bonding with

symmetric bandwidth of up to 45 Mbps■ The best replacement solution for legacy and

expensive lease lines

EFM (Ethernet-in-the-First-Mile), also known as IEEE 802.3ah,

is a matured technology for delivering symmetric bandwidth

to businesses, government offices and organizations with

multiple locations (multiple-site). It allows continuous

standard Ethernet network to reach across the globe,

eliminating non-native transport such as Ethernet over

ATM from the access networks. EFM delivers up to 5.7 Mbps

per line with standard equipment supporting up to 8-way

bonding—a relatively high-performance connection with

up to 45 Mbps bandwidth symmetrically with high stability,

low delay and low packet loss.

Today’s carriers are eager to connect business customers

to their metro networks. The G.SHDSL.bis EFM technology

is the best solution for enterprises with the demand to a

certain amount of transmission over symmetric bandwidth.

It has advantages of maximizing the performance of copper

wire with higher speed and longer distance coverage. By

leveraging pre-installed bundles of twisted-pair cable to

deliver the first-mile broadband network access, ZyXEL

bonded G.SHDSL.bis with EFM solution to smoothen the

issues of fiber-optic cable installation. In addition to offering

different bandwidth packages by using the G.SHDSL.

bis bonding technology, this is the best solution that

enables carriers to expand service offerings in high-margin

enterprise markets.

The use of IP over Ethernet in subscriber access applications

eliminates unnecessary network layers. It reduces the

number of elements on a network as well as the equipment,

operational and complexity costs. Simple architectures

are always easier to manage, especially in complicated

central environments. In the first mile, native Ethernet on

copper or optical fiber networks will provide significant

cost advantage over other technologies. These IP/Ethernet

networks can coexist with time-division multiplexing (TDM)

services.

The ZyXEL IES-708-22A G.SHDSL.bis is an 8-port IP DSLAM

using port bonding to create symmetrical connections; by

bundling up to eight pairs of copper wires, it makes point-

to-point connections of up to 45.6 Mbps possible. With the

multi-pair bonding (ITU G. bond or ITU G.998.1) between

two IES-708s, the data traffic is distributed to the remaining

connections within the group if a link fails. When the link

becomes available again, it is automatically reintegrated

into the group; as such different or unsteady line quality

within the group does not cause any interruption. The

ZyXEL IES-708-22A can be used as either DSLAM or STU-R

(end device) depending on the firmware loaded.

ZyXEL’s P792 G.SHDSL.bis Series complies with the ITU-T

991.2 G.SHDSL, G.SHDSL.bis and IEEE 802.3ah standards

and offers superior Ethernet connection reliability with

unmatched rate and reach. The P-793H Series complies

with ITU-T G.998.1 (G. Bond) and supports 4-wire bundle for

higher bandwidth and longer distance.

With ZyXEL’s End-to-end G.SHDSL.bis with EFM Solution

for business customer edge on customer premises, service

providers can quickly and cost-effectively introduce

profitable broadband services to businesses, governments,

schools and other organizations by fulfilling the demand for

higher bandwidth with manageable cost. Please refer to the

application diagram and supported product tables for more

details.

Annex M is an optional specification in ITU-T recommenda-

tions G.992.3 (ADSL2) and G.992.5 (ADSL2+). This specifica-

tion extends the capability of commonly deployed Annex

A by more than doubling the number of upstream bits. The

data rates can be increased easily depending on the dis-

tance from the DSLAM to homes of the customers. It com-

plies with G.992.1 (G.dmt) Annex A compliant/G.992.2 (G.

Lite), Annex A/L/M and G.998.1 (G. Bond-ATM) ATM-based

multi-pair bonding.

Loop bonding technology provides the telecom industry

with a revolutionary technique to combine multiple

ADSL2+ connections into a single, aggregated connection.

Supporting up to 48 Mbps downstream and 2 Mbps

upstream data rates, as well as high-speed data and derived

voice applications, service providers can offer advanced

bandwidth-dependent services such as broadcast video

and video-on-demand (VOD) to customers beyond the

reach of central offices or digital loop carriers. Bonded

ADSL2+ supports multiple high-definition television

streams at significantly longer distances than other existing

xDSL technologies.

ZyXEL’s boneded ADSL2+ with Annex M solution on the

existing networks for Telcos and service providers. The

solution offers downstream bandwidth of up to 48 Mbps

and upstream bandwidth of up to 5 Mbps using the

bonding and Annex M technologies on two phone lines. We

also offer a solution for bonding a larger number of phone

lines; ZyXEL generally recommends the use of standard

G.998/G. Bond technology for bonding multiple ADSL lines.

The alternative solutions based on non-standard bonding

or load-balancing techniques such as IP tunneling may have

a role to play in certain deployments and we can provide

solutions of this type too.

ZyXEL’s bonded ADSL2+ with Annex M solution provides

the existing ISPs with opportunities to target the profitable

SOHO and SMB markets by differentiated and customized

services. The superior downstream and upstream

capabilities of bonded ADSL2+ combined with relatively

low cost makes the solution particularly attractive to SOHO

and SMB users. The significant attraction to the existing ISPs

is that only part of their existing infrastructures needs to be

upgraded and this can be achieved on a gradual basis as

subscription to the services increases.

ZyXEL’s bonded ADSL2+ with Annex M solution allows

service providers to double the bandwidth over the existing

copper infrastructure and thus leverage their investment to

quickly deploy revenue-generating services like IPTV, VoD

and other premium triple-play applications.

With the ZyXEL end-to-end bonded ADSL2+ solution,

service providers can economically offer services with

higher bandwidth coupled with 802.11n home networking

solutions to their subscribers. This is a prime example of

ZyXEL’s commitment to building exactly what operators

need to remain competitive. Please refer to the application

diagram and supported product tables for details.

3. Bonded ADSL2+ with Annex M Solution

Benefits: ■ The fastest way to achieve positive revenue returns

associated with triple-play bonded ADSL2+

gateways is to deliver these services over existing

copper loops, of which there are over 450 million

worldwide■ Bonded ADSL2+ delivers great data rates over longer

distance than the basic ADSL2+■ Lower CAPEX on investing equipment, lower OPEX

for matured SNMP and TR069 network management

and provision equipments

End-to-end VDSL2 Solutions1. VDSL2 17a Solution2. VDSL2 30a Solution

VDSL2 17a, 100/50 Mbps VDSL2 Solution

The ZyXEL VDSL2 technology supports a wide range of

triple-play service deployments such as voice, video, data,

high-definition television (HDTV) and interactive gaming. It

also enables operators and carriers to upgrade the existing

xDSL infrastructure gradually and flexibly with limited cost.

The maximum downstream bandwidth is 100 Mbps and the

maximum upstream bandwidth is 50 Mbps.

Very-High-Bit-Rate Digital Subscriber Line 2 (VDSL2), or

G.993.2, is one of the most popular standards of the xDSL

family and widely deployed broadband technology. It

allows telecom operators around the world to provide

services such as High Definition TV (HDTV), video-on-

demand, videoconferencing, high-speed Internet access

and advanced voice services, including VoIP, over a standard

copper telephone cable.

VDSL2 includes all the technical prerequisites to address

the backward-compatibility issues of the traditional ADSL

technology. VDSL2 offers telecom carriers a solution that

promises to be interoperable with the ADSL kit that many

operators already have in place. This interoperability will

make customer migration to VDSL2 much easier.

VDSL2 gives consumers speeds of up to 100 Mbps upstream

and downstream at 700 feet and 20-30 Mbps between 2500

to 4000 feet. VDSL2 is an ideal solution to work with the FTTP

(Fiber to the Premises) rollout; for instance, fiber is supplied

directly to an apartment block and copper cable is used to

supply residents with high-speed VDSL2 from there on. It is

also a perfect solution for the last-mile of FTTx deployments

by connecting to remote MSAN (Multiple Service Access

Nodes) via fiber optics interfaces.

Benefits: ■ Offers 100/50 Mbps (17a) and 100/100 Mbps (30a)

bandwidth to fulfill next-generation broadband

access requirements■ True DSL technology to offer multiple HD IPTV

services simultaneously for a digital home user■ Backward compatible with the existing xDSL family■ Best-effort solution eliminates the last-mile

bottlenecks for FTTx solutions

VDSL2 30a, 100/100 Mbps VDSL2 Solution

The VDSL2 30a profile technology is the best solution as a

part of FTTB, FTTC and FTTN. Now the fiber reach range can

be 10km, 20km or up to 60km, and it is the most effective

and low-OPEX approach by integrating the last-mile legacy

copper lines and boosts its bi-directional bandwidth up to

100 Mbps.

ZyXEL’s VDSL2 solution serves as the ideal xDSL technology

for eliminating last-mile bottlenecks, enabling mass

deployment of triple-play services by TR069 for easy

management and allowing carriers to efficiently compete

with cable providers. VDSL2 provides high data rates of up

to 100Mbps symmetrically that are already a mandatory

requirement in many regions for service upgrades.

ZyXEL also provides access equipments of central MSAN,

remote IP DSLAM, environment-hardened to fit in VDSL2

transmission with a series of models in various scenarios;

in addition, with its enhanced long loop reach capabilities,

the VDSL2 system can cover more than 90% of the

households within the POTS network.

ZyXEL is the world’s number-one VDSL CPE vendor since

2008, and the company also offers the second-generation

end-to-end VDSL2 30a solutions on the market in Q2,

2010. The second-generation solutions will offer more

competitive features (such as power management). Please
