Importance of residual stresses in the Brillouin gain spectrum of single mode optical fibers
Impact of ASE on Brillouin scattering of a single-frequency signal
Researchers from Laser Zentrum Hannover e.V., ant the Centre for Quantum-Engineering and Space-Time Research – QUEST, experimentally investigated the influence of amplified spontaneous emission within the Brillouin gain bandwidth on the Brillouin scattering of a single-frequency signal. The experiments were performed for the case of artificial amplified spontaneous emission (ASE) injected in backward direction into a passive fiber, as well as in forward direction of a low-power fiber amplifier.
A significant influence could be observed, when the ASE was counter-propagating to the signal. Injecting 160.6 nW of ASE within the Brillouin gain bandwidth led to a decrease of about 3 dB of the SBS-threshold of an approximately 335 m long passive fiber from about 80 mW to less than 40 mW. At a fixed signal power of 81 mW the backscattered power and the power in the Brillouin scattered Stokes maximum increased by a factor of 19.

AFL Protects Fujikura Technology Wins Lawsuit
AFL Protects Fujikura Technology, Wins Lawsuit against Fiberoptic Hardware, LLC
The judgment was based on AFL's contentions that the Fujikura fusion splicers sold by Fiberoptic Hardware, which were intended for sale outside North America, were materially different from authentic Fujikura fusion splicers authorized for sale in the U.S. in that, among other things, their software was not properly licensed for use in the U.S. and had been modified to alter the language display, and that their sale was likely to confuse purchasers. The judgment was also based on AFL's contention that Fiberoptic Hardware's advertising of those splicers as "new" constituted false advertising.
"AFL is pleased with the judgment, and we will continue to defend Fujikura's technology, patents and copyrights on an ongoing basis to protect our customers from substandard products and services," stated Steve Althoff, EVP for AFL's Equipment Business. "When companies like Fiberoptic Hardware sell altered products, our customers are the real losers. They believe that they are receiving authentic Fujikura goods directly from Fujikura, and they come to find out that they are not. They get confused, and they feel violated because the trust is lost. AFL and Fujikura have a solid reputation, and we will continue to uphold the exceptional standards we have set forth."
AFL filed the case in May 2011, and the U.S. District Court issued a preliminary injunction in October 2011. The permanent injunction entered on May 31, 2012 prohibits Fiberoptic Hardware, along with its officers, employees, and others working with it, from "importing, exporting, distributing, circulating, selling, offering for sale, advertising, promoting or displaying any fusion splicer bearing any of the FUJIKURA Marks" if the splicers have been modified or are not authorized for sale in the U.S. Fiberoptic Hardware is owned by George Kyrias and Chris Wood is the company's sales manager.
AFL is the exclusive distributor of Fujikura fusion splicers and its operating software for the countries located within North America. Fujikura is the worldwide owner of the copyright for the operating software that controls all of its "FSM" fusion splicers.

Fiber Optic Circulators Global Market Forecast and Analysis (2011-2016)
Published: July 16, 2012
Text Pages: 274
Also Included: Excel worksheets – Market Forecast
Fee: From $3,400
The deployment of optical fiber in the metro/access, the continuing demand for upgrading networks to accommodate rapidly increasing bandwidth requirements, plus the need for additional monitoring and testing of the optical fiber networks will drive the steady consumption of fiber optic circulators.
As terrestrial national backbone and undersea systems approaching Tb/s capacities, advanced fiber-optic components, such as fiber optic circulators, are key in enabling DWDM systems with narrow channel spacing to achieve the large numbers of channels required. Fiber optic circulators are used with erbium-doped fiber amplifiers (EDFA), fiber optic sensor applications, dense WDM (DWDM), optical add/drop multiplexing (OADM), optical time domain reflectometers (OTDR fiber optic test equipment), SANs (Storage Area Networks), bi-directional transmission systems, dispersion compensators, and other devices.
This report by ElectroniCast Consultants provides a detailed fiber optic circulator market forecast for each year, 2011-2016. The forecast is presented in terms of Quantity (number of units), Average Selling Prices (ASPs) per unit and Consumption Values. The forecast data for the following regions, plus a Global summary:
· America (South, Central and North America)
· EMEA (Europe, Middle East and Africa)
· APAC (Asia Pacific)
The forecasts are presented in the following application segments:
· Telecommunications
· Private Data Networks
· Cable TV
· Military/ Aerospace
· Specialty Applications
Additionally, the fiber optic circulator market is presented by the following port-count configurations:
· 3 - Ports
· 4 - Ports
· More than 4 - Ports (> 4 - Ports)
Fiber Optic Circulators are non-reciprocal devices, which means that changes in the properties of light passing through the device are not reversed when the light passes through in the opposite direction. The optical device is commonly used in a wide variety of systems, here are just a few examples: dispersion compensation, optical sensors, optical amplifiers, WDM systems, optical add/drops multiplexing (OADMs) and test/measurement instruments such as optical time-domain reflectometers (OTDRs), remote fiber (optic) test systems (RFTS) and other test equipment.
Fiber optic circulator functionality is an excellent candidate for integrating with a transmitter and receiver into a single package. Circulators provide an ideal solution for coupling devices into a fiber optic network without the inherent 3dB loss of an optical coupler. Circulators directional functionality enable simultaneously adding and dropping signals from a fiber as well as coupling other optical signal processing devices.
Fiber optic circulators typically fall into two main classes: 4-port waveguide circulators based on Faraday rotation of propagating waves in a magnetized material, and 3-port "turnstile" or "Y-junction" circulators based on cancellation of waves propagating over two different paths near a magnetized material.
APAC to Win Market Share Lead During 2011-2016, the value is forecast to increase at an average annual growth rate of 7.84 percent. The consumption value is forecast to increase with rising quantity growth partially offset by declining average prices.
The American region (South, Central and North America), was the leader in terms of relative market share in 2011 with the consumption value of fiber optic circulators; however, the Asia Pacific region (APAC) region led by “green-field” telecommunication deployment is forecast to take the market share lead in 2013.
The Europe, Middle East and Africa region (EMEA) consumption of fiber optic circulators is forecast to lag behind; growing faster than the American region, but only one-third as fast as the APAC region.
Consumption is based on the geographical (region) location where the fiber optic circulator is first used into a higher-level sub-component, component, or apparatus. All values and prices, reported by ElectroniCast Consultants, are at factory as-shipped levels, and are in current dollars, which include the effect of a forecasted 5 percent annual inflation rate over the forecast period.
3-Port Leads in Fiber Optic Circulator Consumption In terms of worldwide volume (number of units), the 3-Port fiber optic circulators hold an estimated 88% market share in 2012. Well-over 80% of the 3-Port fiber optic circulators in 2012 are used in Telecommunication applications.
Telecommunications is set to maintain its dominant market share lead throughout the forecast period (2011-2016), in all Port-counts. Specialty applications (R&D laboratory, sensors, test equipment, oil/gas, other) are set to maintain the position of second-place, according to ElectroniCast. Figure 1 shows the global consumption volume market share (%) estimate of the fiber optic circulator market for this year, segmented by Port-count.
MTP-to-LC assemblies now achieve 0.4-dB loss
| July 11, 2012 SYRACUSE, N.Y. – Responding to the need for data centers to reduce the amount of data lost within their network, CABLExpress® recently lowered the maximum assembly loss of its Skinny-Trunk® fiber optic harnesses and trunking MTP® to LC cables to 0.4dB. The Skinny-Trunk line of products allows data centers to adhere to the Telecommunications Infrastructure Standard for Data Centers, or TIA-942, which dictates that a structured cabling environment is the ideal environment for data centers to grow and adjust to changing needs. The lower dB loss rates of the fiber optic harnesses and trunking cables with MTP® to LC connectors offsets the data lost due to adding additional mating points typical of a structured cabling system. “As data centers grow and adopt next-gen networking technologies, fiber network cables must be able to support stricter loss requirements,” says Matt Graham, Director of CABLExpress. “We’re providing the high-performance fiber optic cables necessary to meet these requirements so that data centers can be ready for these changes.” Earlier this year, CABLExpress lowered the maximum insertion loss of its Skinny-Trunk assemblies to 0.25dB by making improvements to the cable manufacturing process and extensive production testing. "CABLExpress continues to lead the industry in dB loss with our Skinny-Trunk fiber optic cabling system," says Graham. "We want to deliver the best value with our products and lowering dB loss provides a maximum return on our customers’ cable investments." The Skinny-Trunk fiber optic assembly comes standard with a lifetime warranty.

ElectroniCast Consultants, a leading market research & technology forecast consultancy addressing the fiber optics communications industry, announces the release of a new market forecast and analysis of the global market consumption and technology trends of filter-based chromatic dispersion compensator modules (DCMs), which are used in optical communication networks. Chromatic dispersion (CD) is due to an inherent property of silica optical fiber, which must be canceled for effective optical fiber communication.
There are three common device techniques to deal with chromatic dispersion in optical communication (fiber optic) networks—the use of dispersion-compensating fiber (DCF); the use of chromatic dispersion-compensating filter modules (DCMs); and electronic dispersion chips (EDCs).
This report presents ElectroniCast’s 2011-2016 market review and forecast of the consumption (value, quantity and average prices) of fiber optic chromatic dispersion compensators filter modules (DCMs) in optical communication networking; also forecast data of the worldwide consumption value of EDCs, DCF and DCMs is provided. Currently, the packaged filter devices (modules) are typically comprised having FBGs (Fiber Bragg Gratings) or etalon-based elements.
In this ElectroniCast market study report, we present forecasts and analysis for the following product areas:
· Fixed Chromatic Dispersion Compensation Filter Modules (DCMs)
· Tunable Chromatic Dispersion Compensation Filter Modules (DCMs)
The market data are segmented into the following geographic regions, plus a Global summary:
- America (North America, Central and South America)
- EMEA (Europe, Middle Eastern countries, plus Africa
- APAC (Asia Pacific)
