Cost-effective single-chip PIC will accelerate the widespread deployment of FTTH networks - single PIC, FTTH-communications industry

This year, China Telecom And China Unicom Have conducted a large-scale EPON equipment Tender , Launched a number of front-line cities of the network access bandwidth over 20M building program, which marked the scale of China's FTTX building has started in 2009 will be the first year of China's FTTX deployment. This year, however, can not become a true FTTH deployment of the first year, because China Telecom and China Unicom also are based on EPON building FTTB + LAN / ADSL-based, real FTTH, little. So, when China started large-scale FTTH deployment to it. This should be the driving force for the development of FTTH. FTTH development from around the world experience, the promotion of several main factors are: technical, business, competition, policy, and cost.

From the technical side, the main competition with FTTH access technology with xDSL, CableModem, WiFi and 3G Mobile Communicate . FTTH technology deployment of these technologies than convenient, low cost, can provide good access bandwidth of 512K-2M, and 2M the following Internet bandwidth has been able to meet the bandwidth requirements of most businesses. At this stage, only access the high bandwidth requirements, such as when more than 10M, FTTH technology only with other access technologies do not have the advantage.

FTTH technology since there is no advantage of low bandwidth, so its development requires high-bandwidth service driven. HD IPTV Is to be recognized and be able to consume a lot of bandwidth, large-scale introduction of high bandwidth services. But Radio and TV Industry in China seems to have been given a special mission, together with departmental interests disputes, China's telecom operators no authority currently operating IPTV. I am afraid that this situation is difficult to change the short term. The short term, operators can make money seem to find other high-bandwidth services. Not enough to promote the business needs

FTTH deployment, operators will need to compete to build because of FTTH network? This situation does exist in some countries. Unfortunately, there are three in China, although the full-service carriers, but they fixed network access between the areas of competition is almost non-existent. China Mobile No access network, China Telecom and China Unicom North-South divide and conquer, penetrate each other a few cities, but specific to an area or building (except for a handful of office buildings) but not at the same time there are two operators, but one or the other . Since the duplication of fixed-line high cost, coupled with the current focus operator is built 3G networks, fixed access network without such a competitive situation will endure.

In some developed countries, policy support is also a driving force to promote the development of FTTH. However, in China, in addition to a number of policies issued to individual local governments, but also do not see at the national level policies. This may be because the three big operators in the oligopoly structure, the operation itself is not much pressure, and no policies to boost the government to build FTTH desire. In addition to operation industry, in the FTTH industry, the state has no special support policies, after all, the industry's share in the national economy is still very small.

In the absence of high-bandwidth services, there is no competitive pressure, there is no support under the conditions of the policy, how to promote the deployment of FTTH network operators in China, thereby promoting FTTH industry development? It seems that only reduce the cost of this road was. FTTB EPON is the form of construction costs should have been able to match with the corresponding copper wire network, so operators have a large building such networks. When one day, the cost of construction of FTTH networks and ADSL down to very, regardless of whether the business needs to keep up, operators will be willing to direct the deployment of FTTH networks.

Then FTTH industry's ability to cost down to this level? The answer is yes. With the tens of millions of lines of EPON equipment procurement, the developed countries to speed up FTTH construction, production scale of enterprises will increase, unit costs will decline. Other technological advances will gradually reduce the cost, for example, are free to bend the fiber reduces the installation costs; PIC technology can reduce device cost; NGPON can reduce the unit cost of bandwidth. Through the efforts of industry, perhaps 3-5 years, FTTH cost levels can be reduced to ADSL. At that time, FTTH can be fully deployed in China.
