The Growing Demand

It was clear as the new millennium began that a remarkable revolution in information services was overtaking our society. Communication, which was confined to narrowband voice signals, demanded a higher-quality visual, audio, and data content. Every aspect of interaction (whether business-to-business, entertainment and social demands, government, or academia) increasingly relies on rapid and reliable communications networks. The Internet alone thrust millions of individual users into a new world of information and technology. The telecommunications industry struggled to keep up with these demands. All predictions that current fiber capacities would be adequate for our needs into the new century have proven wrong. What was once a voice network growing at 4 percent per year is now a data-centric network growing at 30 percent (and more) per year. To meet the demands, the carriers sought help from the manufacturers and the standards committees. They were faced with obsolescence of their entire network infrastructure or a meltdown of the network. The committees went to work looking for a new way to handle this phenomenal growth and unrelenting demand.


Products & Services
Optical Line Terminals
Optical Line Terminals serve as service provider endpoints of a passive optical network by converting between electrical (voice, data, video, etc.) and fiber optic signals while also coordinating multiplexing between the two.
Building Automation System (BAS) Integrators
Building automation system integrators combine sensors, controllers, actuators, PLCs, and operator interfaces into an automatic building asset management system. It is a means of increasing energy and labor efficiency.
Packet Switching Chips
Packet switching chips are communication integrated circuits (ICs) used in packet-switched networks to rout packets between network nodes.
Information Technology (IT) Staffing Services
Information technology (IT) staffing services provide temporary or permanent workers who troubleshoot and repair computers, operate help desks, and support voice and data networks.
Specialty Information Technology (IT) Services
Specialty information technology (IT) services handle specialized or proprietary processes related to IT applications.
