It is recorded that the Houston-based Astro Technology Inc. and the National Aeronautics and Space Administration (NASA) has cooperated and developed a new fiber optic monitoring system this year on two oil platforms offshore West Africa.

The new system Tendon Tension Monitoring System (TTMS) utilizes a fiber optic strain gauge system and a series of sensor clamps to measure the tension on subsea risers and pipelines. It is installed in March on two platforms at the Okume complex for Hess Corporation’s subsidiary Hess-Equatorial Guinea.

According to Nasa, the system can sense any stresses along the platform’s four legs and streams the data in real time, allowing operators to make alterations required to maintain platform’s stability.

During the offshore research, the team attached 16 clamps to two separate drill platforms by commercial divers, using fiber optic cables to send real-time data streaming to a control room on each drill platform.

Astro Technology is specialized in instrumentation and monitoring technologies with a focus on real-time fiber optic sensory systems for oil and gas, has successfully used fiber optic monitoring systems at depths of up to 7,500 feet. This technology was developed as a result of a space Act Agreement, which permits NASA to partner with outside organizations to bring NASA expertise, assets or information to a wide community. Space Act Agreement, which date back to 1958, allows NASA to work with a broad spectrum of partners from all public and private sector discipline, according to NASA’s website.

Nasa chief technologist, Mason Peck, said: “What we learn from testing this technology on the oil platforms will benefit a broad range of terrestrial and space applications, and shows Nasa’s technology investments support America’s future in space and improve our lives here on Earth.”

1Q13 global DSL, PON and FTTH equipment revenue declined 7% compared with 4Q12, down to $ 1.5 billion; although its global sales of EPON and GPON equipment respectively dropped 5% and 4%, Huawei still maintaining its leader position in global broadband aggregation equipment market (world market share of 33%).

FiberStore news, on June 6th, 2013, Infonetics Research principal analyst Jeff Heynen said, broadband aggregation equipment market got a poor start this year, although the performance of various regions and different technical aspects is different, but the overall revenue began a continuous decline from the first quarter of last year.

“EMEA (Europe, Middle East and Africa) suffered a heavy blow, the region DSL, PON and FTTH equipment sales in this region declined by 27% compared with last quarter, ending the growth of previous three consecutive quarters. The EPON sales in the Chinese market have fallen sharply, but due to China Telecom and China Unicom continuing deploy FTTH GPON-based to provide 20M access services, GPON equipment sales in the region has achieved eight consecutive quarters of growth. Meanwhile, as operators increase investment to resist the competition of DOCSIS 3.0 technology, the North American market contrarian, successfully avoided a quarter of weakness as its previous peculiar”, said Heynen.

The highlights of broadband aggregation equipment market in first quarter of 2013

1Q13 global DSL, PON and FTTH equipment revenue declined 7% compared with 4Q12, down to $ 1.5 billion;

Due to seasonal and Russia, the Middle East carriers initial GPON equipment purchase tide coming to an end, and PON equipment sales in EMEA fell sharply by 50% after achieved double-digit growth in two consecutive quarters;

Despite its global EPON and GPON equipment sales respectively appeared 5% and 4% decline, Huawei maintains its leader position in revenue of global broadband aggregation equipment market (accounting for 33% market share);

Google Fiber is Aiming to Breakout the U.S Telecommunication Duopoly Market

Google Fiber is Aiming to Breakout the U.S Telecommunication Duopoly Market FiberStore News, According to the foreign media reports, since its inception, Google Fiber is basically regarded as an experiment in the industry, aiming to highlight the poor performance of the network service providers to promote high-speed broadband services, which is also test platform of next generation of advertising and video technology. Google has been working to correct this stereotypes of people, and repeatedly stressed that it is their serious business to carry out, even if there are indications that they would never in a nationwide promotion of Google Fiber (only a handful of cities deployment)

Media reports fully proved Google is by trying to get people to think more seriously about Google’s fiber optic network project to get it regarded as a major broadband company, although not always the case. Technology News clearly states: This network was initially seen as what the Internet giant used to test its news services and advertising model as an experiment network. Others also would like to know if Google network is just is a mean to promote the existing cable TV and phone companies to provide faster Internet service. Obviously, it was agreed that Google as a rich and powerful technology giant is affordable with this project and simply credited the cost as research and development expenditures.
The reason of Google fiber networks impress on peoples in this way is because that is the truth. This makes Google recently announced the entry into Austin and Prove does not really change that. Google Fiber is an amazing little experiment, although it may ultimately have a huge impact, it is till a long time for it to get rid of “the interesting experiment” (in issues on the U.S market capacity background and connectively)
It is not important that how we call it. Google Fiber MiloMeldin (formerly known as @Home) participate in the association meeting on FTTH in North America this week, and reiterated Google fiber network is a serious money-making initiatives. During the meeting, other than repeatedly requesting for subsidies, deregulation or complaining the poor service (just like the attitude of telecommunication industry’s mobile operators towards the large carries), Google in turns insisted that the earnings of working with the local government is rather abundance.
To be specifically, Google requires Kansas City as the assigned inspector for the Google Fiber project construction to enable speedy completion of the city’s periodic inspection, which will further saves the time and money that Google invest I the construction phase. This company also requires deploy fiber in other cities’ piping, and minimizing the unnecessary street excavation projects. The company has cooperated with the public utility companies to get the supported base station location for connections of the new fiber optic network.
Despite all these sound very good, but as of now, Google has not disclosed any convincing financial data, and Google Fiber has not yet been deployed on a large scale in families except a few part families. Although it is welcomed that Google Fiber intended to break the duopoly U.S telecommunication market, it is still a long way to go if it let people to see it as a real player in the market and a truly disruptive market forces.

Optical Splitters Introduction:

The Fiber Optic Splitter, also named beam splitter, is with multiple input and multiple output end fiber tandem devices, M * N is commonly used to represent a divider with M input and N output.,with coaxial cable transmission system, network system also needs to be light signal is coupled, branch, distribution, and the optical divider is needed for implementation.

Two Kinds Of Fiber Splitters:

Fiber optic splitters are important passive components used in fiber optic communications. Nowadays two kinds of fiber splitters are popular used, one is the traditional fused type fiber optic splitter, which features competitive prices, the other is PLC (planar lightwave circuit) fiber optic splitter ,which is compact size and suit for density applications. Both of these two types fiber splitters has its advantages to suit for different requirement.

Fused Biconic Tapered (FBT) fiber optic splitters are mature technology types, it is low cost and easy to make, but fused fiber optic splitters optical loss are sensitive to wavelength and this is big disadvantages. PLC fiber optic splitters are small size and wide working wavelength, they are more reliable, suitable to use in passive optical network fiber optic splitting, we supply the PLC Splitters including 1*N PLC splitter module and 2*N PLC splitter module .The common configurations are 1×4, 1×8, 1×16, 1×32 and 1×64 PLC Splitters;but 2×4, 2×8, 2×16, 2×32 configurations are also available.

The Theory For Optical Fiber Splitters:

Fiber optic splitter is a device that split the fiber optic light into several parts by a certain ratio.Fiber optic splitters enable a signal on an optical fiber to be distributed among two or more fibers. Since splitters contain no electronics nor require power, they are an integral component and widely used in most fiber optic networks. For example, a 1X4 LC type equal splitting ratio fiber optic splitter can split the fiber optic light signal into four equal 25% parts and sent to the 4 different channels, LC is the connector type on the splitters. Fiber optic splitter key parameters include the optical loss, splitting ratio, isolation, PDL, etc.The diagram below shows how light in a single input fiber can split between four individual fibers (1×4):

Fiber Optic Splitter Features:

  • Single Mode, multimode, and PM fiber types
  • Multiple port configurations
  • Various splitting ratios, 50:50 to 1:99
  • Tube type or Box type
  • PC, UPC, and APC fiber optic connectors
