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 | CED JUNE 2 0 0 2 Networking ADVANCED NETWORKING TECHNOLOGY More power to the bottom line Next-generation services require high-amperage power protection By David Schomaker Senior Product Manager Connectivity Business Unit ADC Telecommunications 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. Integrating new current-hungry highspeed data network elements into a cable network can cause havoc for cable television operators. With manufacturers incorporating higher density electronics and components into smaller-sized packages custom-configured power distribution platforms are necessary to accommodate not only the high amperages but specific requirements of various applications. A well-conceived powering platform will save money resources and customers especially when using cable modem termination systems CMTS laser transmitters and receivers to deliver enhanced data and carrier-class primary line telephone services. Keeping customers happy and reducing churn is critical for operators. And an effective power distribution platform can produce immediate results. Power to the people MSOs have traditionally used AC power at the headend while their telephony counterparts have used DC power. But as cable networks delve into the telephony realm operators are powering much of their revamped network with DC power to preserve services even during power outages. Telephony is a lifeline service-subscribers demand immediate always-on services. When percent service reliability is not only expected but also required .
