In many related policies, driven by large-scale light in to the copper retreat has unfolded, with FTTx substantive, ODN products becoming an important part of FTTx
system, may also be the expansion opportunity.
In line with the statistics, the proportion of ODN access equipment investment taken into account 50% ~ 60% of FTTx equipment investment.Could be predicted the years
in the future our country ODN access device how big the marketplace will keep growth trend in excess of 20%, to 2012, how large the marketplace is predicted to attain
14.55 billion yuan.ODN access products are usually made from optical divider, optical connector and also the equipments install these elements (housing, terminal box,
etc.).ODN core technology is mainly manifested within the optical divider, optical connector, passive optical components products.
Bypass the marketplace popular
PLC (planar optical waveguide technology) optical divider is primarily utilized in FTTH user access network, global curiosity about PLC optical divider in ’09 about
3300 wantong, annual rate of development of 32%.Global markets presents different pattern in various area, Japan, Columbia following a curiosity about high-speed
development for quite a while, has become approaching the gentle, demand is pretty stable, makes up about about 50 % from the share of the market;The outcome from the
economic crisis in the usa, influenced by a specific momentum;And developing countries for example China, India, Brazil’s FTTx a fast-growing construction phase, thus
end up being the main growth reason behind the marketplace.
Using the development of our country FTTx, planar optical waveguide technologies have get to be the growth and development of optical communication industry.PLC market
a hot, many are very bullish on passive optical device manufacturers, will be ready to mount the PLC program.Right now, the PLC in the leading manufacturers of optical
communication technology, rich and rich science, and science, etc.
PLC products around the massive in China telecom and China unicom bidding, driven by domestic PLC market, an order income growth is powerful.Through the 12th five-year
plan, operators will accelerate the FTTx network deployment, that will effectively promote the domestic market requirement for passive components, PLC products since
the core device of FTTx, will get a large amount of applications, inside the global share of the market is predicted to assist enhance.
PLC could be the core from the optical divider chip, the chip is essential to produce and manufacture.Recently, we’ve already had some light components enterprises
successfully on PLC chip encapsulation, most foreign enterprises also transfer chips to the country to encapsulate, these conditions to build up PLC optical divider
industry has built favorable conditions.
The connector has huge potential
Requirement of global optical connector in 2008 to 2008, increased by 11% in the year earlier, last year to a single.04 billion.The downstream applications for instance communication, optical network market demand growth, the influence of is anticipated to achieve 1.63 billion by 2012.
Global optical connector within the consumer market, the American companies are the largest.The oldest along with the future development potential may be the Asia Pacific markets.While using advancement of optical fiber cable technology increase the risk for optical fiber gets closer and nearer to the final outcome user, the shorter links, including board interconnection relating to the needs in the growing, thus promoted greatly rise in the quantity of the connector.
This season countries for the policy within the development and integration of optical communication industry will heighten the size the domestic market of optical fiber connector, promote the introduction of domestic optical fiber connector industry.Domestic industry restructuring and three g licensing as well as other factors to market regarding the optical communication network, the resulting including light to the copper back, “FTTx” and so on the most recent market demand, is a big market possibility of optical fiber connector.
Based on China electronics industry association information center, 2009, 280 million optical fiber connector in the domestic market demand, domestic optical fiber connector from 2010 to 2015 how large industry demand will probably be around 12.6% growth, demand will reach 2012, 410 million.As fiber optic broadband network large-scale construction start, therefore, three major telecom operators entry to the building construction is anticipated being orderly development of optical network, optical fiber connector market scale continuously grow.
1. The background of the project:Radio and television networks in recent business growth is faster in a given area, is the region development education network access project, due to the previous optical fiber network resources is mainly used in cable television network, optical fiber resources is not so rich, many county to the town had no residual fiber resources, to increase the data business, now want to be in the original on the fiber optic cable TV network transmission using again, plus infomation data signals, or want to lay out the other cable?Is the main work, need to solve as many towns in this area belongs to mountainous area, cable laying is not very convenient, considering various factors such as resources, cost, on the radio and television networks company specialized in optical network access technology co., LTD. Shenzhen Fiberstore CWDM system to conduct a comprehensive performance analysis and product testing.And start in areas such as education network access to A project on each node USES many Fiberstore CWDM system equipment.
2. Network topology
CWDM access scheme
1.Save fiber resourcesCWDM (Coarse where division multiplexing) Coarse wavelength division multiplexing system, which USES optical multiplexer in the different optical fiber transmission wavelength multiplexing in a single fiber transmission;On the receiving end of A link, using wavelength multiplexer and then revert to the original wavelength, using optical fiber all the way, on the whole link is solved effectively under the condition of the optical fiber resources extremely nervous network access, this scenario, A, D, E, between transmission on A single fiber and four 10/100 MBPS (also can be 1000 MBPS) signal, A room – B node is in the original cable TV signal transmission on A single fiber loading 2 10/100 MBPS signals, save A lot of fiber resources. 2.More business and high bandwidthCWDM is a according to the practical application to the transfer rate of adaptation based transmission platform, support a variety of business transfer.At each wavelength, the support of the business including 10 m / 100 m / 1000 m Ethernet, 155 m / 622 m / 2.5 G of SDH, 155 m / 622 m ATM business, as well as the Fiber Channel business, and so on.The whole system capacity to play a few Gbps data signal.Fully meet user bandwidth requirements in quite some time.This scenario USES is 10/100 MBPS business with cable TV signal for hybrid transmission.
3.Cost-effective, to facilitate the network upgrades
CWDM in hybrid access network in the use of the business
With the improvement of people’s living standard, nowadays a single network access gradually cannot satisfy people’s demand for network now, CWDM system support for the characteristics of business more and more get the attention of people, can also provide E, FE, GE, STM 1/4/16 SDH and ATM signaling, CATV video interface and other businesses such as access CWDM system solutions, to meet the requirements of people now.
