Ø PON is short for Passive Optical Network.ØThe structure of PON is point to multi-point (P2MP).ØPON comprises Optical Line Terminal (OLT), Optical Network Unit (ONU) and Passive Optical

Splitter (POS).

Working Principle of PON

u An uplink wavelength of 1310nmu Each ONU sends data to the OLT within the

time period allowed.u No collision detection is required.u No packet fragmentation

u A downlink wavelength of 1490nmu The OLT sends blended data to each ONU

through a splitter.u Each ONU only accepts specific data and

drops other data.

Ø PON is a passive optical network without active devices, which greatly cuts down maintenance costs.Ø A small number of network components lead to the decrease in failure points and operating expenditure.

Advantages of PON - Bandwidth

Ø The demand for bandwidth increases rapidly and other access technologies fail to meet such demand at present.

Ø PON technology provides the bandwidth that can suit the need in the long future.

Advantages of PON –Long Transmission Distance

uEthernet: 0.1 KMu The transmission distance of 100m is the main problem for Ethernet as the access

technology. It can extend the transmission distance only through cascaded switches. The increase of active devices will lead to the increase of the failure points in the network, which greatly weakens network reliability.

u xDSL: 1-5 KMu For xDSL technology, the transmission distance depends on the maximum

bandwidth. Usually, operators will not provide subscribers with xDSL access at its maximum rate for the consideration of long distance and unified charge; therefore, the actual access rate is lower.

u In the districts with a small number of subscribers, operators still need to install expensive IP DSLAM devices.

uPON: 10-20 KMu PON technology supports a transmission distance of 10-20 KM with a high

bandwidth. It helps Ethernet and xDSL to provide longer transmission distance and bigger bandwidth. It makes the deployment of access solutions more flexible.

PON is a natural broadcast network. In the PON, the single-fiber WDM technology add the CATV signal into PON on the OLT side by Multiplexer and splits it on the subscriber side through the De-multiplexer. This enables PON to transmit both data and CATV signals.

u Mainstream technologyu The application of Ethernet accounts for 90% of global LAN market shares.

u Analysis shows that BPON will drop out of the market in recent years. EPON will become the mainstream technology in Asia and Asia is the largest PON market in the world.

u Standardization trendu IEEE standardizes EPON, which is earlier than ITU-T standardizing GPON. The 802.3 standard of

Ethernet proposed by IEEE is the most important standard of the industry. Currently, most of GPON products comply with the EPON standard and no products strictly comply with the GPON standard. There is no supply of mature GPON chips.

u Another reason why EPON products are more widely used than GPON products is that the EPON standard enables vendors to flexibly manufacture such products.

u Maturityu From the perspective of industry chain, the core of the EPON is PON optical transceiver, which is

mature. The core TC control module has been manufactured in large scale. The core module of the

GPON system is not mature and the GPON is hard to be come into large-scale commercial operation.

Comparison Among Main Access Technologies

All carriersCATV carriersTelecom carriers having telephone line resources

Telecom carriers having telephone line resources All carriersMain

carriers

It is the final solution to broadband access. It will be applied in a large scale.

It will be gradually washed out.

Hard to be predicted

It will be well developed in the coming three to five years. It is hard to predict the development after five years. It is certain that it will not be washed out soon.

Due to many active nodes, the network fails to meet carrier-class requirements. It will be washed out of the market of residential subscribers.

Future

It will be applied in a small sale.

The situation cannot be improved.

Maybe it is used. Only the telecom carriers having telephone line resources can use it in a large scale.

It is a promising technology.

It will focus on the access to MAN. It is not fit to develop it in a large scale to serve residential subscribers.

Near future (1-2 years)

Not applied popularly yet

It is not suitable for current market and is hard to be developed. Now It is mainly used in the cities with a population of less than 0.5 million.

Not applied popularly

Up to now, it is well developed and has a few problems. The bandwidth is 512 KB or 2 MB, which is not sufficient. In China, there are about 25 million ADSL subscribers.

It has been popular in the past few years, but has a few problems currently. Its development of speed slows. E.g,In China, there are thousands upon thousands of subscribers. The resident carriers are hard to operate.

Currently

Note: PON, one of FTTH technologies, is regarded as the best FTTH technology currently.

www.h3c.com 15

FTTx Market Development Trend

u In the globe, 66% of broadband subscribers use DSL, and in China, up to 90% of broadband subscribers use DSL. Currently, China is the first largest DSL market and develops slow in terms of FTTH. Both mainstream telecom carriers and emerging access providers do not deploy FTTH technology. The governmental departments in charge does not make systematic policies and measures to develop and promote FTTH.

u Starting from year 2004, FTTH is a rising star in the telecom industry. E.g, In China, due to its expensive price, FTTH is not widely accepted. As prices of optical components and fibers are decreased, FTTH is predicted to be gradually developed in the coming four to five years.

u In Asia, FTTB is widely accepted by carriers. Vendors shall provide FTTB solutions.

u The development of national IPTV service brings an opportunity for EPON. The use of EPON helps to address the issue of insufficient bandwidth provided by DSL.
