When IP-enabled picocells first came onto the scene, they appeared to offer a new alternative to operators facing difficult coverage (and capacity) challenges. But they also made operators feel a bit uncomfortable. Using IP for backhaul made a lot of sense… but it was unfamiliar for network planners used to their trusted tools.

FlexWave MMW 100 is a point-to-point millimeter wave transmission system that operates in the licensed 71GHz to 86GHz spectrum and provides fiber-speed wireless Line of Sight (LOS) communications links within a 1 – 6 km range. The MMW 100 features a 10” lens instead of a 2’ antenna making the product suitable to mount on electric poles and any other medium without the restrictions of high pointing stability. The MMW 100 has the largest beam width allowed by the FCC in the 71-86 GHz band (1.2 deg.)....

Deploying fiber to MDUs, such as apartment complexes, condominiums, townhouses, and other multi-family locations, represents a lucrative market for broadband service providers. At the same time, these applications present unique challenges in both greenfield and overbuild scenarios. This paper addresses the key elements of MDU construction practices, including the physical plant from backbone to premise and the architectural decisions required for a successful MDU application. It will also cover additional network considerations for equipment and connectivity techniques....

What’s inside counts. That statement sums up customer expectations about wireless service inside offices, homes and public places such as malls, hospitals and subway stations. Wireless service providers have a vested interest in meeting those expectations: When consumers and business users are convinced that indoor coverage is reliable and nearly ubiquitous, they’re far more likely to believe that their mobile phone can be their only phone. That belief helps wireless carriers’ bottom lines by increasing average revenue per user (ARPU)....

End-to-end TrueNet® Structured Cabling System: Category 6 cable for data, Category 5e cable for voice, angled patch panels, relay racks, Glide Cable Management System, and modular jacks/outlets for work areas.

ADC’s Cable Management Solutions for Active Platforms are a family of cable management solutions for active equipment. These solutions enable service providers to maximize their capital equipment investment and minimize operational costs.

Increasing capacity and network applications create new challenges for both the planners who design and the operations personnel who maintain the network. A managed density approach that takes a long-term view of data center design is key to ensuring maximum density and growth without disrupting operations that can cause a huge drain on productivity, profits, and service availability. Successful network managers should always take into account the importance of planning and maintaining data centers to maximize density and minimize maintenance hassles....

The continued thirst for energy is a recurring story in news headlines every day. Global warming forecasts rising temperatures, melting ice, and population dislocations due to accumulation of greenhouse gases in our atmosphere from use of carbon-based energy. There are strong arguments for and against the dire predictions of global warming, yet one fact is undeniable—over the past 10 to 20 years, the inhabitants of Earth are collectively consuming more energy at a faster rate than ever before.

As a technical undertaking, 10GBase-T is an accomplishment of signifi cant proportions. Th e engineering eff orts required to create a protocol for transmitting 10 billion bits of data per second on eight copper wires are worthy of celebration and marvel.

ADC expands the industry-leading FlexWave WMX WiMAX product family with the introduction of an economical series of base station radios operating in the 5.4 GHz and 5.8 GHz bands. WMX is the first system offering Dynamic Frequency Selection (DFS) compliant with US and ETSI standards and operating within the WiMAX profile. Subscribers enjoy the benefits of enhanced link-reliability even under interference conditions. Service providers and network operators can generate aggressive return of investment (RoI) from the use of license-exempt 5 GHz frequency band....

As network equipment such as routers and switches, continues to evolve, changes in proper cable-management techniques and recommendations must also keep up with the times. Routers and switches are being marketed with higher densities and more capabilities. These higher-density platforms have more cables feeding them and require more power. More powerful equipment gives out more heat, so careful airflow and thermal management is more important than ever. Density within a single cabinet is increasing. Upgrades every few years (or less) are to be expected, therefore cables should be routed in a way that maximizes accessibility and intuitive maintenance. When as much as 70 percent of network down time can...

Active equipment manufacturers are increasingly building DWDM transceivers that use the multifiber MPO connector. While the MPO provides a compact interface on the transceiver card, most service providers require single-circuit access. This creates the need for a conversion from the multifiber MPO to a single-fiber connector. ADC’s Fiber Management Tray (FMT) is a compact two rack-unit termination panel that features industry-leading cable management and ADC’s sliding adapter packs, thereby enabling safe single-circuit access. The FMT can also be configured with high-quality MPO to LC breakout cables that provide the connectivity between the DWDM transceiver and the FMT panel....

Facing the prospect of delivering bundled services that are nearly as complex as the subscribers who demand them, today’s service providers require an evolved network that can bring more bandwidth to more places. The combination of network technologies that can increase bandwidth and connectivity solutions that can ensure optimum reliability and improve service quality is essential in meeting the growing demands by business and residential customers.

It may sound bold to say we have the best video jacks in the world, but we can say it with confidence. Just take a look inside one of our Super Video Jacks and you’ll see why. Our jacks are loaded with features that make them work more reliably and last far longer than other jacks. To achieve SMPTE 292M high-frequency performance and minimize signal radiation in or out, ADC standard size jacks feature a unique, patented, two-piece sliding center conductor. Also, the center conductor employs a special closed-entry design to resist insertion of a damaged connector or a test probe, preventing damage. The precision, gold-plated...
