CommScope unveils hydrogen fuel cell cabinets for enterprise backup power

CommScope recently unveiled its hydrogen fuel cell solution, designed to provide reliable backup power for small-to-medium enterprises in North America. The new outdoor cabinet fuel cell can provide up to 16 hours of reliable, environmentally-friendly backup power to enterprise core business computing systems. The system is enabled through CommScope's existing partnership with Hydrogenics Corporation, a global specialist in designing, manufacturing, building and installing industrial and commercial hydrogen systems.

"Natural disasters, such as hurricanes, have shown us that traditional backup power generators can be unreliable when put through the test of time and exposure to the elements," comments George Brooks, senior vice president, enterprise product and market management, CommScope. "These generators are commonly powered by fossil fuels and emit greenhouse gases including carbon dioxide. As fuel prices continue to fluctuate, businesses are searching for an alternative that is more reliable and has less of an impact on the environment."

CommScope says its hydrogen fuel cell solution converts chemical energy directly into electrical energy without any combustion. The system is designed to provide highly efficient, reliable and uninterrupted backup power for commercial building systems without the need for costly regular maintenance. It does not emit any greenhouse gases and the only by-products are heat and a small amount of water, notes the company. The proton exchange membrane hydrogen fuel cells are housed inside an outdoor environmentally secure cabinet, about the size of a phone booth--a smaller footprint than other solutions currently available on the market, claims CommScope.

"This is a smart fit for businesses, such as banks, large retailers and other commercial buildings needing something they can count on to keep their business systems operational, without interruption, anytime there is a loss in power," Brooks adds. "Hydrogen fuel cell technology not only has a lower total cost of ownership, but provides an opportunity to meet sustainability goals through an alternative power solution that is clean, quiet and runs on an abundant resource. Hydrogen is safer than fossil fuels and I'm confident we will see more uses for it in the coming years."

Last year, CableLabs, the non-profit research and development consortium for the cable television industry, deployed the CommScope fuel cells to provide 16 hours of reliable, environmentally friendly backup power to its headend and cable modem termination system at its headquarters in Louisville, CO. In 2011, the Society of Cable Telecommunications Engineers (SCTE) deployed a similar hydrogen fuel cell system to provide backup power to its data center at its headquarters in Exton, PA. Those fuel cells were called into service during Hurricane Irene in 2011 and Hurricane Sandy in 2012. During the severe weather, the fuel cell provided sufficient backup power until normal power was restored.

CommScope said it will also be expanding its PartnerPRO network to include partners who will assist customers with site planning, installation, commissioning and ongoing maintenance of the backup power solution.

Senko intros LC-HD connector for high-density applications

Senko Advanced Components has introduced its new LC-HD high density LC connector. The Senko LC-HD's design utilizes a flexible "pull-tab" allowing for the connector to be disengaged easily from densely loaded panels without the need for special tools. The company notes that the overall height of standard LC connectors requires a small vertical space above and below the LC adapters. The low-profile Senko LC-HD, by virtue of its pull tab, allows LC adapters to be stacked while taking up absolutely no vertical space. According to Senko, because the LC-HD connector can be removed via its simple pull tab, the design eliminates the need for finger access to the LC connectors' latch mechanism; therefore, LC adapters can now be mounted much closer together.

Report: $8.5B to be spent on carrier WiFi equipment over next 5 years

Infonetics Research released its latest "Carrier WiFi Equipment" report, which tracks WiFi equipment deployed by operators in public spaces for wireless internet access.

According to the research, globally, revenue for carrier WiFi equipment, including wireless access points and WiFi hotspot controllers, totaled $338 million in the first half of 2013. Carrier WiFi revenue had already surpassed 2/3 of total revenue for the prior year, says the report. The majority of carrier WiFi access points are also WiFi hotspots, notes Infonetics.

"Over the 5 years from 2013 to 2017, operators will spend a cumulative $8.5 billion on carrier WiFi equipment, led by mobile operators using carrier WiFi for data offload," reveals Richard Webb, directing analyst for microwave and carrier WiFi at Infonetics Research. "This strong growth will gain additional impetus from the proliferation of small cells with integrated WiFi over the coming years."

The data finds that North America has consistently dominated carrier WiFi revenue share since 2007, though by 2017 a regional share shift to Asia Pacific and EMEA is expected. As the carrier WiFi market evolves and more operators launch carrier WiFi services, Infonetics also expects fluctuations in vendors' market share, with the top 5 positions--currently held by Cisco, Ericsson, Huawei, Ruckus, and Alcatel-Lucent--potentially shuffled.

802.3 Ethernet standards-development projects target PoE, NG-EPON

The IEEE has initiated three new standards- development projects, as well as an 'IEEE Standards Association (IEEE-SA) Industry Connections' activity, all intended to expand the capabilities and relevance of the IEEE 802.3 Standard for Ethernet. According to IEEE, work is underway to amend the base standard in multiple ways so that it is more useful in emerging application areas, while the new Industry Connections activity aims to engage global industry in discussion of the next-generation Ethernet Passive Optical Network (NG-EPON).

The new standards-development projects include the following.

  • IEEE P802.3br "Draft Standard for Ethernet Amendment Specification and Management Parameters for Interspersing Express Traffic" is being developed to address the market need in emerging IEEE 802.3 Ethernet application areas such as audio/video, automotive, industrial automation and transportation (aircraft, railway and heavy trucking) to cost-effectively converge low-latency and best-effort traffic streams on the same physical connections. Currently, such functionality requires multiple networks with parallel links, but, when completed, IEEE P802.3br would amend the base standard to support interspersed express traffic.
  • IEEE P802.3bt "Draft Standard for Ethernet Amendment: Physical Layer and Management Parameters for DTE Power via MDI over 4-Pair" is being developed to address the market need for more robust and efficient Power over Ethernet (PoE) capabilities. Applications such as pan/tilt/zoom security cameras, Internet Protocol (IP) videophones, kiosks, point-of-sale (POS) terminals, thin clients, multi-radio wireless nodes and access points, laptop computers, RFID readers and building management have demonstrated need for more power. When completed, the new IEEE 802.3 amendment would be intended to increase the power and efficiency of PoE.
  • IEEE P802.3bu "Draft Standard for Ethernet Amendment: Physical Layer and Management Parameters for 1-Pair Power over Data Lines" is being developed to extend PoE to data terminal equipment (DTE) via a single twisted-pair IEEE 802.3 Ethernet connection. The availability of power on the single-pair data interface would remove the need for separate power wiring for applications in emerging Ethernet markets such as automotive, transportation and industrial automation.

Also, the IEEE 802.3 Industry Connections NG-EPON Ad Hoc group has been launched to explore the market potential and technology options for an NG-EPON operating at data rates beyond 10 Gbits/sec. EPON is widely deployed for a number of applications, including residential and commercial subscriber access (for voice, video and data) and mobile backhaul. Equipment vendors and network operators, particularly in Asia and North and South America, are interested in exploring the technologies available for the next generation of EPON, notes IEEE.

RF Industries adds low PIM Mini DIN adapters for DAS

RF Industries now offers between-series adapters for the 4.1-9.5 (Mini) DIN, 7-16 DIN and N type interfaces. The company notes that advanced wireless systems such as distributed antenna systems (DAS) require RF components that, in addition to being highly efficient in signal transfer, bear low passive intermodulation (low PIM) properties. The company maintains that the N-type interface design is over 70 years old and has been replaced in many wireless site applications with the larger 7-16 DIN interface for better electrical and PIM performance.

For its part, the company adds that the 4.1-9.5 (Mini) DIN is essentially a compact version of the 7-16 DIN with similar electrical performance. All of the new adapters by RF Industries are manufactured with brass bodies in durable non-tarnish tri-metal (white bronze) plating with a PIM rating of less than or equal to -155dBc.

Eight variations of the new adapters are available. They are: 4.1-9.5 DIN male to N female (RFN-1046-4); 4.1-9.5 DIN male to N male (RFN-1045-4); 4.1-9.5 DIN female to N female (RFN-1047-4); 4.1-9.5 DIN female to N male (RFN-1048-4); 4.1-9.5 DIN male to 7-16 DIN female (RFD-1681-4); 4.1-9.5 DIN male to 7-16 DIN male (RFE-1682-4); 4.1-9.5 DIN female to 7-16 DIN female (RFD-1683-4); and 4.1-9.5 DIN female to 7-16 DIN male (RFD-1684-4).

Available from the company's RF Connectors distributors throughout the U.S., Canada and Mexico, all low-PIM products from RF Industries are 100-percent tested to assure performance.

Fastback upgrades intelligent backhaul radios to enable wireless multipoint services

Fastback Networks recently announced an expansion of its Intelligent Backhaul Radio (IBR) product line to include support for both multi-point-to-point (M-PTP) and point-to-point (PTP) architectures, along with the company's new Extreme Interference Protection (XIP) features, as well as the launch of the ETSI-compliant device into the European market. Fastback's IBR is an intelligent wireless transport device that enables high-density LTE, LTE-A, and the future LTE and WiFi radio access networks, with what the company claims is an industry-first transport mechanism for wireless delivery of fiber equivalent services in both line-of-sight (LOS) and completely non line-of-sight (NLOS) conditions. This new class of wireless device comprises an integrated carrier-grade switch and radio purpose-built for the requirements of new mobile networks.

According to Fastback, with its new M-PTP feature, the IBR delivers multipoint economic leverage while still preserving a fiber equivalent Service Level Agreement (SLA) on each link, which the company calls "an unprecedented capability" in a wireless backhaul solution. This feature extends the IBR's PTP throughput and latency performance to multiple end points, providing greater coverage with fewer devices for LTE macrocell and small cell backhaul. As well, commercial and wholesale services can aggregate multiple ends points for economic leverage without compromising SLA requirements. Also new to the platform, Fastback's XIP features enable support for usage of unlicensed wireless spectrum. The company notes that requirements for high-performance LTE backhaul require far more spectrum capacity for backhaul, impacting capacity constraints for licensed bands and creating a challenge for mobile operators. In the past, unlicensed bands were rarely used for carrier-grade mobile backhaul because the devices could not effectively mitigate interference.

Now, the XIP feature, incorporating Fastback's patented algorithms for interference mitigation, enables the IBR to sustain the high-throughput and low-latency service requirements of LTE backhaul while simultaneously mitigating even the severe levels of interference common in unlicensed spectrum. According to the company, the XIP feature mitigates the effects of uncoordinated and self-interference to enable new applications of unlicensed spectrum, including LTE macrocell and small cell backhaul. Fastback says the IBR's new interference mitigation capability enables sustained, carrier-grade performance in unlicensed spectrum to a SLA. This functionality establishes new levels of certainty and reliability for use of unlicensed spectrum, along with the advantages of tapping hundreds of MHz of available 5-GHz spectrum to relieve the capacity constraints of licensed bands.

"The IBR assures fiber-equivalent services over wireless, effectively creating fiber fill-in and enabling mobile network operators to extend the reach of the service edge to provide anytime, anywhere access to services," comments Kevin J. Duffy, CEO and cofounder of Fastback Networks. "We continue to expand the features and capabilities of the Fastback product line, providing the new requirements for speed, latency, and SLA assurance critical to LTE interfaces, such as S1 and X2, and essential to enabling emerging high-density mobile networks."

The Fastback solution is currently in trials with Tier 1 and 2 mobile network and services operators in the U.S. and Europe, and deployed in first office application carrying live traffic in the cities of Los Angeles and New York. The ETSI-compliant IBR will be available beginning in the second quarter of 2014. The M-PTP capable IBR will be available in the third quarter of 2014.

Molex intros MPO/MTP flexible-boot cable assemblies

Molex has unveiled its FlexiBend MPO/MTP flexible-boot cable assemblies, which the company says are especially designed to optimize cable routing and support low-profile installations where cabinet doors or front panels might interfere with traditional, straight-style, bend-limiting boots. The assemblies feature flexible bend-limiting boots that allow cable exits in varying positions from straight to a 90-degree angle.

The new optical cables are intended for use in datacom, telecommunications, medical, and industrial equipment cabinets and rack-to-rack applications. "Optical cable routing grows increasingly challenging when installing hundreds of fibers in dense optical patch panels," asserts Eve Leal, product manager at Molex. "The FlexiBend MPO/MTP flexible-boot cable assemblies help solve cable routing issues by giving installers the ability to bend and direct the exiting fiber in any direction within tight configurations like equipment cabinets and high-density racks."

Molex says the FlexiBend assemblies are designed with strain-relief boots that use a flexible and durable steel internal wire, which allows an installer to position the boot in place. The "stay-in-place" boot provides strain-relief, but can easily be repositioned without disconnection in order to modify routing requirements while the cable is in service, adds the company. "Manufacturers and installers of high-density hubs, router and server equipment need the right tools to effectively manage cable routing in compact spaces," continues Leal. "Designed to be bent by hand, the round-cable MPO/MTP FlexiBend boots can be positioned as needed--0, 45, 90 degrees--for easier installation and maintenance of cable plant."

Available in 12- and 24-fiber round-cable options, the FlexiBend assemblies are compatible with any MPO receptacle or active QSFP, CXP and CFP modules, says Molex. Singlemode and multimode cables provide options for transmission link distances using Om3, Om4, OS1 and OS2 fibers. Further, the MPO/MTP FlexiBend boot cables have been mechanically tested to GR-1435, Issue 2 specification to ensure product performance over 25 bends in various positions.

The new Quantum Handheld splicer replaces the company's previous TomCatType-25eU/S/M model, adding automated features for user-friendly and high-performance fiber splicing for FTTx, data center, and other communication network connectivity applications.

The new Quantum Type-QH201e-VS handheld's advanced fusion splicing technology incorporates a fully navigational touchscreen interface for maximum user friendliness (a traditional keypad also is included). Further, the new unit's Internet interface ensures 24-7 remote diagnostic and maintenance support capabilities from Sumitomo Electric Lightwave's On-Time Service Center technicians. An included SD port allows for virtually unlimited data storage for software, training, video, and audio uploads/downloads.

"Our goal is to innovate continuously to offer customers the most advanced and reliable fusion splicer technology backed by the most expert and responsive support and service," comments Dwayne Holst, product manager at Sumitomo Electric Lightwave. "As the only company to offer Internet-capable 24-7 remote maintenance and service, this exemplifies our commitment to unprecedented customer support."

Sumitomo claims that, in general, its Quantum Handheld V-Groove splicers boast the industry's smallest footprint (110W x 140D x 76H mm) for maximum portability, as well as the fastest 12-second typical splice time among handheld splicers for improved efficiency in space-constrained work areas, typical with FTTx and data center deployments. The company notes that the small footprint of the Quantum Handheld does not compromise the splicer's rugged design, which complies with the most stringent shock, waterproof, and dust-resistance requirements.

Other features of this RoHS-compliant splicer include an easy-to-use fiber-holder system, extended-life electrodes, built-in help and maintenance videos, and compatibility with Sumitomo's Lynx2 CustomFit Splice-On connectors. The new Quantum Type-QH201e-VS splicer was unveiled at OFC 2014 (March 11-13) in San Francisco, CA.

Researchers at IBM send 64-Gbit/sec data over 57 meters of multimode fiber

Calling attention to data they delivered at the OFC Conference and Exhibition in early March, IBM researchers announced they successfully sent data at a rate of 64 Gbits/sec over 57 meters of multimode cable using vertical-cavity surface-emitting lasers (VCSELs).

"The achievement demonstrated that the standard, existing technology for sending data over short distances [multimode fiber] should be able to meet the growing needs of servers, data centers and supercomputers through the end of this decade," the researchers said. They characterized the speed-and-distance accomplishment as "about 14 percent faster than the previous record and about 2.5 times faster than the capabilities of today's typical commercial technology."

To achieve these speeds, the researchers used VCSELs developed at Chalmers University of Technology in Sweden and custom silicon-germanium chips developed at IBM Research. "The receiver chip is a unique design that simultaneously achieves speeds and sensitivities well beyond today's commercial offerings," said Dan Kuchta of the IBM T.J. Watson Research Center in New York. "The driver chip incorporates transmit equalization, which widens the bandwidth of the optical link. While this method has been widely used in electrical communication, it hasn't yet caught on in optical communication."

The researchers used standard non-return-to-zero (NRZ) modulation. Kuchta noted, "Others have thought that this modulation wouldn't allow for transfer rates much faster than 32 Gbits/sec. What we're showing is that's not the case at all. This technology has at least one or two more generations of product life in it." IBM pointed out that some researchers believed achieving higher-than-32-Gbit/sec transmission rates would require turning to more-complex types of modulation.

Kuchta further explained, "Researchers typically rely on a rule of thumb that says the usable data-transfer rate is about 1.7 times the bandwidth. That means that with the VCSEL laser, which has a bandwidth of about 26 GHz, the rate would be only about 44 Gbits/sec. What we're doing with equalization is we're breaking the historical rule of thumb."

IBM maintains that the fast speeds achieved only worked for a distance of 57 meters, so the technology is most suitable for transmitting data within a building. About 80 percent of the cables within data centers and most, if not all, cables used for typical supercomputers are less than 50 meters long, the company further stated.
