“Within the metro will be the need to install, test, and reconfigure all types of equipment with the same fundamental operational procedures and principles used in large, carrier-class networks historically. Any other approach is inherently risky.”

When it comes to the structured cabling system, however, the aesthetics of the components are often not considered. So while space planners argue over carpet choices and wall art, the decision criteria for physical layer projects are normally limited to functionality and price – which makes sense because most brands of cable managers, cable, and patch panels offer both a similar appearance and performance within defined requirements. Decisions based upon function and price also makes sense because the structured cabling system usually is hidden from view with cables behind walls and within Telecommunications Rooms (TRs)....

Every business needs an edge. Many industries—from consumer electronics to household appliances to automobiles—have successfully gained an edge with digital components and production methods supported by digital devices. The drive to digital is apparent in wireless voice and data communications, too, as networks migrate toward IP-based architectures, software defined radio, and other technologies. The digital edge isn’t just convenient. The digital edge translates into bottom line benefits for wireless service providers....

Fiber optic connectors are produced by polishing their endfaces to create a smooth domed shape. If the shape or endface geometry is precisely controlled, the result will be physical contact between fiber cores when two connectors are mated together. The polishing process creates a very small damaged layer at the tip of the fiber that has a higher index of refraction (index layer) than the glass before the damaged layer. Since reflections in optical fiber are caused by changes in index of refraction, it is the index layer that causes the return loss associated with a mated pair of connectors....

Cable television has changed. No longer just a medium for delivering television signals, it has evolved to deliver the most advanced multimedia services in communications. Multiple system operators (MSOs) are building and rebuilding their networks to compete with local telecommunication companies for revenuegenerating high-speed data and primary line services. As these next-generation services demand higher levels of bandwidth, high-amperage power protection becomes increasingly critical for network integrity....

ADC's Universal Remote DSX Panel eliminates the need to support multiple DSX-1/3 panels in the outside plant environment. With its modular design, the universal panel saves space without sacrificing quality. With one panel, a variety of modules can be combined to support almost any variation of DS1/3 handoffs. The commonality of components allows fewer, less expensive modules to be warehoused, avoiding missed installation dates due to lack of inventory.

ADC’s Value-Added Module (VAM) System provides the flexibility and functionality to easily incorporate optical components into the network. Optical components, such as wavelength division multiplexers (WDMs) and tap monitors, add capacity and increase reliability with minimal installation cost and time. Wavelength division multiplexers enable the service providers to double the capacity of the existing network without installing new fiber; tap monitors provide easy access to the network for testing and monitoring without interruption of service....

For many buildings and campus environments, voice, data and Internet communications are supported with DS-1 services. Yet as demands for bandwidth continue to increase, DS-1 is proving insufficient for some applications. Today, DS-3 is more than just "nice to have". It has become a necessity. Extending DS-3 services over longer distances to select floors in a building or to buildings in a campus is required.

Extending Reach Beyond CSA Range for xDSL Services

For services providers, there are thousands of customers beyond the Carrier Service Area (CSA) range of 12kft. While each of these customers today represents main and perhaps second line service revenue, they are all prospects for increased revenue from higher speed services such as ADSL.

Using two pairs of copper wires to provide T1 transport delivery, HDSL4 maintains spectral compatibility beyond the carrier service area (CSA) range as well as on repeatered loop applications. Service providers can realize numerous benefits by deploying this latest advancement in symmetric DSL services. For instance, the technology offers extended reach and spectral compatibility with ADSL. In order to make optimal DSL technology deployment choices, though, service providers need to carefully analyze the application before selecting technologies and the associated equipment....

With today’s unforgiving marketplace dictating fiscal frugality, fiber connectorization methods are under intense scrutiny. Network operators have long faced the decision of terminating fiber panels in the field or purchasing pre-connectorized fiber panels from the manufacturer. A simple cost analysis reveals pre-connectorization at the factory encourages quick deployment, minimizes operational expenses and ensures network integrity.

Wavelength division multiplexing (WDM) remains the prevailing technology for adding flexibility and functionality to today’s optical networks. By transmitting signals at different wavelengths through the same fiber, WDMs can multiply transmission capacity, improve testing, and transmit voice services over video. Value-Added Module (VAM) systems equipped with WDM technology are used in a variety of applications to reduce operational expenses and increase revenue opportunities.

With the emergence of broadband, service providers are able to offer combinations of data, telephony and video distribution services, increasing their subscriber rates and maximizing revenue-generating opportunities. Value-Added Modules (VAMs) equipped with optical splitters can cost-effectively distribute signals to multiple subscribers. The modules provide operators with unmatched flexibility and functionality.

In today’s competitive environment, service providers cannot risk any interruption in service. Finding a problem before it becomes a hard failure does more than just prevent loss of service, it affords service providers sufficient time to address the problem appropriately. With troubleshooting often posing a large, time-consuming expense, service providers have discovered new methods for nonintrusive test access of fiber circuits. A Value-Added Module (VAM) system equipped with monitor modules provides more flexibility and functionality in a variety of monitoring applications....

Then at the end of 2001, FSM Telecom discovered ADC’s compact GSM and CDMA systems for developing countries and hard-to-serve areas. The result was that FSM Telecom could costeffectively build small-scale networks throughout the islands that could contend with the extreme climate conditions. In addition, satellite backhaul is optimized and implemented cost-effectively due to the advanced compression technology in the ADC system.

As a long-time supplier of IP network infrastructure to cable multiservice operators (MSOs) around the world, ARRIS has built a strong reputation for high-quality products that work as advertised. ARRIS provides operators of broadband local access networks with video, highspeed data, mobile and fixed-line telephony systems for the delivery of voice, video and data to residential and small-to-medium sized business customers.

In the early 1950s, most investor-owned telephone companies in the United States refused to serve rural areas of the country, claiming it was too expensive to do so. Several residents of northeast Alabama, like many of their counterparts around the U.S., realized that if they and their neighbors were ever going to get reliable communications service, they would have to provide it themselves. Consequently, they set up Farmers Telecommunications Cooperative (FTC) with the idea of making sure that residents and businesses across sparsely-populated DeKalb and Jackson Counties would have access to the same kinds of services that urban Alabamans enjoyed. Throughout the 56 years that have elapsed since then, FTC's...
