2.IntroductionThe modern society exhibits increasing demand to utilize new communicationservices. Today, new services are offered in different packages using standard

(copper) networks for cable television and telephony. As both networks havetheir specific advantages and disadvantages, for successful future proof exten-sion and development of new services, a network should be applicable that of-fers the best of both worlds.

Together with its partners, Funea Broadband Services has developed an inte-grated network solution using smart FTTH technology in a transparent form,thus enabling all kinds of services through one infra-structure.This infra-structure integrates both a full duplex Ethernet based network usingone single-mode fiber and a downstream broadband network using a secondsingle-mode fiber.

The broadband solution allows using standard radio and TV-sets by the sub-scribers to receive and record a rich choice of programs like they used to viaHFC-networks, without needing a set-top box for digital/analogue conversion.In-home distribution of the programs is also easy possible using standard coax-ial solutions.The Ethernet based network applies for all other data-services as well as the in-teractive part of services offered on the broadband distribution network.Our solution offers an almost unlimited bandwidth for the subscribers withouthaving to overload the Ethernet network with large capacity needing stream-ing video applications!

This document contains information regarding FTTH solutions offered by FuneaBroadband Services bv. As our company is not focusing on offering all aspectsof a FTTH network, our line of business will be described together with our vi-sion on FTTH.

3.Services supportedConsidering existing services offered by the traditional service providers for theconsumer market, it is obvious that at least Internet Access, CATV and Teleph-ony are supported. Also it is very interesting observing traditional service pro-viders to grow from single service to multi-service providers. The incumbent te-lephony provider is offering Internet Access over the same copper wires (using

ISDN/DSL) and the traditional CATV operators are also offering Internet Accessand even Telephony over their HFC-networks.Of course, new services are discussed and only limited by the imagination of thehuman mind. So the network must never be the limiting factor and the FTTHsolution offers virtual unlimited bandwidth needed for multi-service providing.

Overview of possible communication services applicable for the FTTH multime-dia network.

RF-broadband network part:

Distribution of standard radio and TV programsBroadband transmission of analogue signals using the standard

frequency range 47 to 862 MHz. To prevent overload of the data

distribution network, and to enable using standard equipmentlike video-recorder, TV-set and radio. Transmission capacity up to50 PAL TV-channels and more than 30 FM radio-channels.

Pay-TV or Pay-per-viewBroadband transmission of additional QAM-signals containingcoded TV-channels for pay-TV and/or pay-per-view applicationsusing standard DVB set-top boxes. Interactive services via theEthernet network interface. Transmission capacity up to 50 QAM-signals containing more than 500 different video-sources.

Volume dataAdditional transmission of large data-blocks using dedicatedQAM-channels for asymmetric broadband applications likestreaming video in interactive games.

Ethernet network part:

Internet accessDirect internet access without the need of a dial-up network.Scalable configuration depending on subscribers needs.

Telephony over IPTelephony can be handled by IP (Internet Protocol) using theEthernet network equipped with switches that support quality of

service for real-time services. This new service allows users tophone directly through the IP network or connect to the PSTN(Public Switched Telephone Network) via the IP network.

Pay-TV and Pay-per-viewInteractive connection for the broadband set-top box to handleall data needed for information and ordering of paid TV-programs and/or radio programs.

Other services- E-service systems

- E-commerce- computer games- tele-working- remote learning- remote surveillance- remote monitoring in-home equipment- tele-shopping- telemetry

This are all examples of services possible on the multimedia network.

Each service is basically running on a separate virtual network using standardsolutions available on the market place today. The Data Network is based on

open standard technologies such as Ethernet and Internet protocols. This en-sures cost-efficient expansion and development of both the network and newservices.

The broadband part complies to European EN50083 and IEC60728-1 standard,thus offering a transparent RF-broadband platform for the distribution of ana-logue and digital encoded video and audio channels. RF user-interface allowsconnection of standard home equipment and coaxial in-house cabling.

Also, it is very important that equipment at customers premises provide stan-dard interfacing (RJ11, RJ45 and F-coax) to allow existing end-user equipmentto easily connect to the FTTH infrastructure.

4.System architectureIn the next figure the differences between possible Ethernet configurations isevaluated.

In our opinion, the system architecture should be based on a point-to-pointEthernet Layer 3 switched network concept. Architecture using EPON (Ethernet

Passive Optical Network) technology was also considered but as there is nostandard protocol defined today nor expected in near future, the choice was

made for point-to-point. APON (ATM Passive Optical Network) is using stan-dardized protocols but turns out to be much more expensive and less flexiblethan EPON or point-to-point.The following table comparing EPON with APON, clearly shows the advantagesof EPON and is worthwhile considering when a standard is defined:

Ethernet PON (EPON) ATM PON (APON)

Standard IEEE ??? FSAN, ITU G.983Authors - NTT, BT, etc.Date - 1995Speed 1.25 Gbps 155/622 MbpsIP efficiency good not-so-good

Multiple Access TDMA, other TDMAScalable yes, 10 Gbps difficultONU features routing, switching, firewall,

etc.--

LANs Ethernet --Home PNA Ethernet --Components IP/Ethernet ATMCost Ethernet cost (low) ATM cost (high)

The conclusion is that ATM PON uses an expensive non-IP-optimized ATM-protocol at low speeds (OC-3), while Ethernet PON is using low cost, IP-optimized Ethernet protocol at high speed (GigaBit). (source: IEE802.3 EFM SG)

5.AdvantagesThe principal advantages of the suggested FTTH Multimedia Network are listed

below:

Based on open standard technologies such as Ethernet, Internet Proto-cols, DVB and PAL.

High bandwidth for data in both directions for internet and local ser-vices

Additional high downstream RF-bandwidth for analogue and digitaltransmission

Excellent scalability, simple adding of nodes, hubs, users and services

Privacy and easy management warranted using individual VLANS per ser-

vice and user

Adjustable transmission speed depending on requirements and chargingof the user

Fast Ethernet access from 10/100 MB, limited only due to the speed pro-vided by the ISP

Easy configuration and administration using dedicated Network Man-agement System available on the market place today

Transparent network set-up, open for multiple service providers

Quality of service is assured within the access network

Broadband RF-network complies to European EN50083 and IEC60728-1standard

High-quality transmission of standard analogue radio and TV signals

Subscribers can use standard radio and TV equipment; set-top boxand/or AD-converter only needed for additional services

Fully replaces both traditional networks for telephony (twisted pair) andbroadband (coax)

6.In home networkOur MediaBox (XON router version) provides up to 7 interfaces for the in-homenetwork:

- 4 x RJ 45 UTP-port for Ethernet;

- 2 x POTs (VOIP)- F-connector for RF broadband.

Interfacing suitable for standard UTP, standardtelephony and standard coaxial cabling systems insubscribers residences.Optional version with a wireless Ethernet extensions (WiFi) will avoid UTP ca-bling in subscribers residences but is moreexpensive.

But as it is, the MediaBox offers a transparent

solution for three basic services:- mass data (IP based services);- telephony (VOIP);- cable-TV.

Of course, additional equipment like IP-based orQAM-based set-top-boxes, etc. will allow extraservices as listed before, but this kind ofequipment must not necessarily be part of the (basic) network provisions. Itcould be part of the (basic) service provisions allowing spreading of investmentsand lower risks for network operators.

Next to extra In-home devices, adding services like voice-over-IP will result inhigher demands on Gigabit Ethernet switches used in the network, that mustbe able to provide quality-of-service adjustments for this purpose.So before implementing a FTTH-system, it has to be totally clear what equip-ment is part of the network and what equipment is part of one (or more) ser-vice(s).

The construction of the MediaBox allows for finishing of fiber in a separateprotection unit in the subscribers residence. Depending on the services to bedelivered, different versions of the MediaBox can be easily installed on top ofthe protection unit or even a sealable cover can be installed in case fiber finish-ing only is needed.

The in-home cabling must be as simple aspossible not charging subscribers withadditional costs for optical wiring etc. Also itmust be possible to easily connect existingdevices like TV-set, Radio and Video Recorder aswell as PC and/or Laptop. Using standardcabling as mentioned above, will provide easyconnecting of this equipment.

7. TopologyThe network topology of the Multimedia Network is based on Fiber To TheHome technology, combining the best of both Worlds available on the market

place today: single fiber (dual wavelengths) Switched Ethernet Network andsingle fiber Broadband Distribution Network.The Ethernet part uses router interface for the ATM/SDH backbone, feeding theredundant 1000base or 100base city trunk (ring-topology). Layer 3 switches inthe area-pops are used feeding the 100base point-to-point last mile (star-topology) to the media-boxes in the customers residences.

Detail of last mile star-topology using WDM (1310+1550 nm) technology forEthernet communication over one single-mode fiber per subscriber:(Area POP = WTR)

NC or AREA POP SUBSCRIBER ONU

The RF-broadband part over the second single-mode fiber uses an EDFA (opticalamplifier) interface for amplification of the optical RF-signals from the back-bone. This backbone normally will be a redundant 1550 nm link to the regionalhead-end or city-POP.New, cost effective techniques are used for the high-power EDFAs feeding thelast-mile. An optical switch at the input of the NC allows redundant opera-tion. The 8 outputs providing the 13 dBm power to feed eight 64-way splittersfor the access-network, thus allowing to cover at least 512 subscribers per EDFA.Although it will be possible to locate the splitters near the subscribers havingthe advantage of using less fibers, it is obvious that cost of fiber-finishing instreet-cabinets will turn out to be much more expensive than using more fibers.If a special FTTH fiber-solution is applied, using 2 (pigtail) fibers per mini-tube,clever network-design will result in low-cost fiber-finishing not needing expen-sive fiber- management.In simple man-holes, only the tubes are separated and fed into the relatinghome-connection.

The quality of the RF-signals distributed is in accordance with the European

EN50083 and IEC60728-1 standards (C/N 45 dB).

T -pplement, low-cost Ethernet equipment with RX/TX single-mode fiber interfaceThe broadband transmission also requires single-mode fiber and because of thelow attenuation of the fiber, the last-mile to the subscriber can easily be fedfrom the area-pop (or WTR). This implies that the link to the customer is a di-rect fiber-link to the area-pop (WTR) without any active or passive elements foamplification or splitting.

8.Network ManagementThe RF-equipment (EDFAs, Transmitters ed.) has standard RS 485 interface with

HTTP protocol, as well as a SNMP interface for alarm gathering and status in-formation.This interface passes information for both status-monitoring and element man-agement.For status monitoring, Cheetahs Netmentor NMS and CableWatch (Bktel) soft-ware is used in several HFC-networks, allowing status monitoring of all opticalRF-equipment.

As the optical receiver will most probably be part of the Ethernet Media Con-verter, status information is limited to the monitoring of optical input-power(yes/no). This information will be passed to the SNMP manager of the Media

Converter thus allowing the overlay NMS to also monitor the converter.

Again due to our line of business, an extended description with functionality ofa dedicated Network Management System is not in this paper.

10. CompetencesThe competences of Funea Broadband Services bv are focused on the transmis-

sion of broadband RF (PAL-TV /FM-Radio/QAM/QPSK) between head-end andsubscriber, using FTTH technology. In our point of view, a switched 10/100 MbEthernet based FTTH network with integrated IP-video streams, does not pro-vide enough bandwidth to provide subscribers constant access to variousvideo/audio programs on all standard TV-sets and video-recorders like they usedto via a HFC-network.The success of FTTH will be the combination of both networks using the sameinfrastructure but different fibers: two (or three) fibers to every subscriber.Based on this view, we have developed our MediaBox with integrated full du-plex Ethernet transceiver and RF-receiver, providing a complete data and videosolution. Also we are open to any supplier offering Ethernet based end-to-end

FTTH systems, to integrate our RF-solution. We can provide the necessary opti-cal RF-receiver as a plug-in unit, using our competence to discuss and definewith supplier both mechanical lay-out and electrical/optical interfacing, to fitperfectly in suppliers subscriber unit.
