Be prepared to look at the development of optical communication industry
Wall Street analyst team Doyle Publishing Ltd yesterday wrote on SeekingAlpha analysis of financial performance of the leading companies in the field of optical devices Finisar's. Their conclusion is pessimistic. If they have a good analysis, whether our industry in trouble fast.
In fact, a few days ago Finisar CEO Eitan Gertel sudden resignation if he had let the outside world because of poor financial performance of Finisar resign, although officially denied this claim Finisar. Doyle analysis to verify the financial problems may encounter Finisar. These problems can be summed up that is Finisar's profitability fell again, and the reason is behind the rise over the past few years COGS costs faster than sales growth. As a direct result, Finisar's ROA is only 0.07%, ROE was 0.1%, which means that management is no return to investors. This means that even if investors put money in the bank than to vote for Finisar in exchange for higher returns.
Finisar Doyle conclusion is not supported by the current earnings outlook for the stock now. We are not the financial industry, for their analysis and conclusions can not comment. But from the feeling we live in the optical communications industry, the costs continue to rise should be an indisputable fact, more than Finisar, other optical device manufacturers face the same. Finisar has the leading technology in fact there are new technologies and products to improve profitability, most of their competitors do not have this power.
Market prospects for the optical communication industry, all these years of rapid development FTTH, data center, driving the rapid growth of optical devices and fiber optic cable and other markets. Now China Mobile to host the 90 million core km of fiber optic cable is an example of the bidding market hot. Today, however, Doyle read this article, but people have some concerns. After all, the world macroeconomic situation is also far from clear, the Americans say that the increase does not raise interest rates to observe the performance of the Chinese economy, China's own ability to maintain 7% in the second half of the growth or problems. Optical communications market in Europe has just improved, and now into a refugee crisis. Russian oil prices dragged down the market far less. Development of optical communication market growth depends on the bandwidth consumed by an unstable economic situation is difficult to say to have stable bandwidth consumption growth. Today, we still see the Wall Street Journal said that Verizon is expected to next year's estimated income levels and unchanged from 2015, is one of the reasons behind the rapidly changing needs of consumers.
If even Huawei said his far without success, so for today's optical communications industry, especially optical components industry, vigilant even more indispensable.

Competition status and trends of soft cable
1. FTTH with a soft optical cable
FTTH customer base with a soft optical cable main suppliers, competition in this area is mainly between traditional cable companies, and professional soft cable companies due to lack of brand influence, market channels is imperfect, the lack of scale advantages, it is difficult to enter the fields. But due to the current FTTH market with a soft optical cable capacity is relatively small, so the market can not accommodate too many cable companies, the market concentration degree will be far higher than ordinary cable, over the next three to five companies expected to occupy 80% of the market share, and currently occupy the forefront of the enterprise market will likely further expand the advantages, the industry average profit margin would be in a more reasonable level.
2. The optical connector device with a soft optical cable
Unlike soft FTTH optical cables and optical connectors for flexible cable customer base is a communication device manufacturer and device class manufacturers, more than the number of such enterprises, a relatively small-scale enterprises. Before 2005 professional soft cable companies occupy the market, but after 2005 with the expansion of market demand, the traditional cable companies quickly cut into the market, by virtue of its good brand image as well as the scale of strength and technical strength, coupled together with ordinary cable cost advantages and fiber resources supporting the formation of scale procurement of raw materials, the market share of traditional cable companies in the field of rapid increase, severely squeezed the soft cable professional living space, and this trend will become more pronounced. It can be expected, a few years later, the existing professional soft cable companies will gradually withdraw from the mainstream market in the field, the market will be the preceding several traditional cable business division.
From the application point of view, the optical connectors for flexible cable market capacity will not be great, and dispersed customer base, pre-equipment and research and development into a larger, more post-market investment, and general profitability and many other reasons, so new entrants were underpowered, the future market structure will remain relatively stable.

Fixed construction potential solutions - VDSL
"Broadband China Strategy" by 2020 China's fixed broadband subscribers to reach 400 million fixed broadband household penetration rate reached 70%, the number of Internet users reached 1.1 billion urban broadband access capacity of 50Mbps, rural broadband access capacity 12Mbps. How to effectively implement such an ambitious communications project is placed in front of the major operators of a problem. China from the current mainstream carriers fixed construction situation, FTTH undoubtedly get the operator's favor, but full use of technology to achieve FTTH broadband speed, how many there are some problems, such as high construction costs, low profitability, engineering deployment long period, the old district FTTH difficult, interoperability and so on. So, how to solve these problems the operator's problem? VDSL technology is a promising solution.
From the perspective of technical maturity perspective, VDSL technology in Europe, North America, after years of business we have been popular. FTTH construction interoperability issues that exist in a relatively different manufacturers PON and PON terminal between the central office, the interconnection and VDSL VDSL central office terminal has been quite mature. VDSL infrastructure currently the main chip only Broadcom, Lantiq, Ikanos, the mainstream of the terminal VDSL chip includes Broadcom, Lantiq, MTK, Triductor, Ikanos, central office and terminal chip must follow the DSL interoperability specification TR67/TR100/TR114, and must Broadband Forum the IOP testing before commercial DSL interoperability lab. VDSL equipment interoperability is guaranteed by the main chip firmware, qualified VDSL CO or CPE main core must Broadband Forum certification, including TR67 (ADSL), TR100 (ADSL2/2+), TR114 (VDSL2), TR115 (VDSL SRA etc) specification test. Chinese shipments of mainstream VDSL terminal chip manufacturers have Broadcom, Lantiq, MTK, Triductor, 2013 China Telecom organized the interoperability testing VDSL, including interoperability testing G.vector, G.INP and other advanced features of the ideal test case and can meet the requirements of different manufacturers interoperability. In addition, VDSL terminal chips in addition to support VDSL2 central office, but also backward compatible with ADSL/2/2+, ADSL and VDSL to meet then mixed scenarios.
From the perspective of the carrying capacity in terms of bandwidth, VDSL technology also meet the 2020 Chinese urban broadband access broadband China strategy proposed to achieve 50Mbps, 12Mbps rural broadband access capacity requirements. VDSL2 technology is quite mature, with a capacity of over 300 meters 50Mbps bandwidth. In addition, Vectoring technology has been in commercial quantities in 2014, found within 300 meters downstream can support 100Mbps of bandwidth capability, within 500 meters of 80Mbps bandwidth capabilities. G.fast technology is expected after 2015 with commercial power to support bandwidth capability within 100 meters of 1Gbps. Therefore, VDSL+FTTB or VDSL+FTTC this application mode can well meet the requirements of broadband speed broadband China strategy.
From the perspective of the construction costs, the use of FTTH technology deployment laying fiber to the home network requires a comprehensive, but VDSL technology can take full advantage of the existing network of the original copper line resources already deployed in some twisted family, if need to deploy VDSL, you do not need to reproduce the wiring line cost savings. Secondly, VDSL network without deploying FTTH networks like optical splitter, optical connectors and other devices, which are very expensive period, saving the cost of network components. In addition, VDSL terminal and infrastructure costs are much lower than FTTH terminal and infrastructure costs, which reduces the equipment cost. Overall, construction costs line VDSL users about one-third of the construction cost of the first-line PON subscribers. This cash-strapped operators provincial company or to the city, it means they can spend less money, construction of a high-bandwidth network, which also meets the requirements of the national broadband strategy.
From an engineering point of view deployment, FTTH network construction is equivalent to re-building the access network, the central office OLT main work includes deployment, debugging, fiber optic cabling, terminal and infrastructure interoperability testing and so on, a long construction period. The VDSL network deployment is relatively simple, and can utilize the existing copper line resources, eliminating the need for network cabling link, simply replace the ADSL central office VDSL central office, and there are no interoperability issues, VDSL terminal equipment can be directly and VDSL infrastructure equipment to achieve docking, greatly simplifies the difficulty of engineering deployment, while compressing the construction period and construction costs of the project deployment.
Simply put, in China FTTH construction in full swing wave, there VDSL technology still has great significance:
(A) for the network construction funds tight provinces or cities, you can take advantage of VDSL technology for broadband speed, while saving construction costs;
(B) to ensure high-bandwidth fiber to the home at the same time an effective solution to difficult issues, improve user viscosity;
(C) the requirements for the network construction period short speed network transformation project, the network may consider the use of VDSL technology to FTTB+VDSL or FTTC+VDSL way to achieve broadband speed, significantly shorten the construction period.
Here are the main scenarios VDSL terminal:
(A) DSLAM upgrade part of the current network by ADSL DSLAM support the board upgrade to VDSL cards, VDSL gateway can be directly mounted at DSLAM, ADSL cat replace user's original VDSL terminals, broadband upgrade and provide IPTV, OTT etc. can control business.
(B) replace the existing ADSL infrastructure by MDU
If the original can not be upgraded to support VDSL DSLAM central office, FTTB+VDSL technology can be used in new residential MDU or replace the original can not be upgraded DSLAM. VDSL gateway can be directly mounted in the MDU, the user to replace the original cat ADSL VDSL terminals, broadband upgrade and provide IPTV, OTT, etc. can control business.

Singtel Tay Soo Meng, chief technology officer, said the company has 70% of customers use fiber-optic network, and believe continued innovation through the latest technology to provide better speed to the user. Given that most families there are many networking devices, coupled with the increase of bandwidth for various applications and requirements, the relevant technology is expected to meet the needs of users.
Singtel Singapore is the leading fiber-optic network services market share exceeds 50%, the current Singtel-eat fiber-optic network services to provide only up to the rate of 1Gbps, after upgrading to new technology customers will choose to 10Gbps broadband service can cater to high-definition 4K video service quality at 10Gbps transfer rate, 50GB of movie in one minute will be able to download.
In addition, 10Gbps of bandwidth can benefit online games, telemedicine, 3D television, but also support future 8K television service.

FTTH difficult five crux, light copper binding or a recipe
In March 2012 the Ministry of Industry has announced plans to achieve nationwide coverage FTTH 35 million households in the year, but a dream awake, "fiber to the home is difficult," "Broadband is not wide," the problem did not get solved. The implementation of the light to change so that Chinese netizens project was eagerly looking forward to, but the reality is cruel, slow process of reforming the unbearable, too many users expressed anger and dissatisfaction. China's broadband network construction shortcomings presented more worrying, rectification imminent. FTTH really that difficult? What is the reason? There is no solution?
Originally a technician can hold 10 ADSL broadband every day, the light changed only a day to complete two.
Fiber to the home, a stumbling block too much.
1, high-care costs, expensive charges, operators, equipment manufacturers, users tripartite coordination difficult;
2, property slotting allowance, the operator, the property is difficult to coordinate the two sides;
3, most of the building, the old district no internal embedded fiber optic lines, which makes the transformation more difficult and more time consuming to install;
4, after the light changed, fixed must be connected to the power supply, the power went out in a hurry very tangled;
5, some people need some people do not need, it is difficult unified, carrier pressure.
Of course, in China this population, the relationship between a complex environment, there will be this kind of problem, fiber to the home difficult, already reasonable.
Expert Weapon: "Light copper" Combined, hybrid deployment
Earlier reports said that, in addition to improving network speed through fiber transformation, utilizing copper technology also enables certain bandwidth of 12M, or 16M. There is also news that a foreign telecommunications equipment manufacturers announced last year new technology "VDSL2 Vectoring" has been achieved under the conditions of the use of copper, the family of bandwidth up to 100M.
In this regard, communications Standards Institute Ministry of Industry and Telecommunications Research Institute, deputy director Li Ao said that the current building is not embedded inside most of the fiber-optic lines, fiber to the home to a large scale, it means to be in an existing building internal re-laying of fiber optic cable. Fiber itself impatience tension and bending characteristics, determine the layout of the optical fiber is much more difficult than copper. He believes that "fiber + copper" combinations can be used as an important reference and select the current broadband construction.
