Fiber Distribution Hubs (FDH) continue to play a vital role in supporting rapid deployment and connection in FTTP networks. Innovation in FDH design occurs at a rapid rate and next generation features appear in newer FDH enclosures. Key innovations include:

The NCX-1000 is a passive fiber-to-the node (FTTN) service delivery cabinet that is easily placed in the feeder or distribution plant to support any re-sectionalizing or broadband overbuild application. It is typically installed with an adjunct DSLAM cabinet or remote terminal that houses a broadband DSLAM. The compact cabinet is designed for FTTN applications where re-sectionalizing the network requires either a new cross connect interface with a 1:2 ratio of feeder to distribution pairs or for 1:1 ratios where ADC’s patented Distribution Intercept (DI) service delivery solution is used. The NCX-1000 family of cabinets supports up to 900 feeder circuits and 1800 distribution circuits with 432 DSLAM...

Continued cellular market penetration, burgeoning consumer demand for wireless rich media, and the promise of even more data-intensive applications continue to drive bandwidth consumption, fueling an estimated 100 percent increase in the global number of cellular base stations by 2009. 3G and 4G cellular services, which require very low latency and packet-based switching, place additional burdens on existing infrastructure, taxing copper backhaul solutions to their limits. As a result, the cost of leased lines, which currently accounts for approximately 15 percent or more of operational expenditures (OPEX), will increasingly burden service providers who continue to expand aging architecture to meet their expanding backhaul needs....

There are many considerations regarding the outside plant portion of any fiber-to-the-premise (FTTP) network architecture. Each area must weigh in on issues of cost, flexibility, performance, accessibility and other important criteria. As fiber gains momentum for use in delivering high-speed broadband services to homes and small businesses, questions have surfaced regarding the best way to connect the large numbers of drop cables feeding into the network.

Network infrastructure has seen remarkable changes in the past 20 years. Major application transformations and massive upticks in bandwidth requirements have been met head-on with the need for smaller, less restrictive and higher performing cables. The fiber revolution has found its niche, but desktop applications and many data center needs have continued down the copper path. While much has changed, the early and resilient adoption of UTP cabling has been an industry mainstay, and the reasons for such are as sensible as they are compelling....

In order to assess endface quality, manufacturers and users of singlemode fiber optic connectors use magnification to visually examine fiber optic connector endfaces. Workmanship defects such as scratches, pits, and cracks, when located in the wrong area of the endface and when severe enough, can cause high insertion loss and/or low return loss. Locations and severity of defects, as well as the degree of magnification used in inspection, must be defined to ensure consistent connector performance. A survey of fiber optic connector manufacturers and end users produces a variety of endface workmanship requirements and procedures. This paper covers the following topics:...

The NCX-1000s service delivery cross connect is designed for customers who use the Emerson CoolPed™ cabinet for hardend DSLAM applications.

As service providers continue upgrading their networks to transport high-bandwidth broadband services, an increase in fiber usage is essential to meet both bandwidth and cost requirements. But just deploying this additional fiber is not enough – a successful, well-built network must also be based on a strong fiber cable management system.

ADC’s TrueNet® IP Security Cabling System is the integrated portfolio of high-performance copper and fiber cable, connectivity, and cable management products from ADC. The precisely tuned TrueNet system exceeds TIA/EIA standards and provides a clear path for uninterrupted IP data and video throughput within the entire network.

In simple terms, a passive CWDM implementation involves placing VAM modules and upgraded transmitters and receivers at each end of the network segment. CWDM equipment performs two functions: 1) segregates the light to ensure only the desired combination of wavelengths are used, and 2) multiplexes and demultiplexes the signal across a single fiber link.

Fiber-to-the-X (FTTX) network applications increasingly include Multi-Dwelling Units (MDUs) as part of the network build—often accounting for over 40% of the target subscriber base. The MDU segment of an FTTX network is the “last mile” or distribution end of the network, representing the demarcation point for electronics and home wiring where the end user is connected in the more densely populated MDU applications (i.e. apartments, town homes, campuses).

No matter what you call it, adding fiber to the local loop is a major strategic initiative for a number of carriers. Fiber to the customer premises represents the ultimate broadband connection for the end user, and promises to help carriers deliver value-added services while increasing the average revenue per user. While a great deal of attention is focused on the outside plant (OSP) implications of FTTX deployment, FTTX creates a number of critical issues at the central office (CO), including: • Space reclamation as higher-density fiber frames and WDM equipment require a larger footprint than POTS equipment • Upgrades to passive and active network equipment elements • Infrastructure...

Delivering Voice over Internet Protocol (VoIP) services is a promising scenario for many cable operators. Unlike circuit-switched telephony, VoIP offers new opportunities for advanced and differentiated services, such as real-time call management, integrated messaging, interactive logs and ubiquitous call notification. While VoIP seems promising, it’s also daunting. VoIP is a disruptive technology that’s being fueled by a rapidly growing and highly competitive broadband market. Its success in international call traffic shows its potential for challenging existing business models. Its proliferation in both consumer and enterprise markets also shows that VoIP is inevitable....

The provider that can attract and retain customers, bundle attractive new services and decrease overall costs will succeed where others fail. The right network infrastructure is critical to any success. Utilizing the best resources to help manage network deployment and optimization efforts will greatly improve the outcome of these projects. Finding a highly reliable single- source provider of program and project management services – a resource that knows telecommunications networks, regardless of equipment, platform or service – will have a direct effect on a carrier’s bottom line....

For lots of different reasons, many carrier networks today are too complicated. Rapid growth, merger and acquisition, and increased demand for high-bandwidth services led to network-on-top-of-network, creating inefficiency and inflexibility. Now, many network infrastructures are too complex to update without causing major upheaval. With unnecessary complexity comes unwarranted costs. So it makes good business sense to improve the efficiency of existing operations to reduce both capital and operating expenses. The problem is that many networks are so complicated that it’s hard to know what really exists in the existing operation. That also makes it hard to plan for the future....

Every operator knows that a well-planned network makes for reduced complexity, lower costs and fewer service issues. Unfortunately, the reality is that many operators have fewer resources dedicated to network planning and design. With new network equipment options, new transmission and transport alternatives and increased service demands, engineering decisions are becoming increasingly complex.
