Go the Distance by Getting More Fiber Into Your System

Posted by Ronnie Pennington | Sep 30, 2020 9:37:57 AM

The evolving sophistication and range of video surveillance, security and communications systems, and the increased data loads required by each continues to drive the use of fiber optic networks for these applications. According to the Guide to Fiber Optics from the Fiber Optics Association (FOA), long distance or exterior applications increasingly call for fiber cabling as most of these systems are designed to be used over distances and speeds that preclude anything but fiber. The FOA adds that surveillance systems continue to proliferate in buildings, especially governmental, banking, or other buildings that are considered high security risks.

While coax connections are common in short links and structured cabling advocates say you can run cameras limited distances on Cat 5E or Cat 6, fiber continues to become a much more common choice for security systems. Network-centric security solutions like video surveillance systems and access control require two types of connection; copper or fiber optic cabling to provide IP data connectivity, and copper cabling to provide power for device operations. As the standardization of Ethernet and PoE with category cable, have improved the distribution of centralized power and data communications from the head-end network switches and power supplies, has increased and installations costs have dropped.

There are several solutions available to extend the distances of PoE network links, including media converters that accommodate most any combinations of coax, UTP, Ethernet and fiber infrastructure. And while the 328 ft. maximum distance for Ethernet and PoE connections has essentially remained unchanged for more than 30 years, manufacturers like Altronix offer solutions that dramatically increase the distances for Ethernet connectivity using fiber optic cables. In fact, fiber optics can accommodate great distances for 10/100/1000 Ethernet connections, with 50-micron OM3 laser-optimized fiber solutions rated for up to 550 meters (1804 feet).

Media converters are now commonly used to integrate copper network equipment and fiber. Since DC power cannot be conducted over fiber, PoE media converters using hybrid cabling provide the ideal solution to extend network distances via fiber to remote IP cameras. Such solutions can help integrators build their network from scratch or expand existing by allowing organizations to leverage existing infrastructure or supplement legacy cabling with fiber all while supporting various system protocols and data rates.

Altronix has been a leader in developing solutions to more easily integrate the use of fiber for professional security system applications. Altronix NetWay Spectrum series takes fiber and power to a new level with indoor and outdoor models that include hardened Ethernet PoE+ switches and rack mount media converters with or without integral power. NetWay Spectrum solutions can be deployed with conventional single or multi-mode fiber, as well as composite cable that combines fiber with power to simultaneously deliver both, power and data. They also feature embedded LINQ™ Network Management Technology to remotely monitor, control and report power/diagnostics – streamlining service and maintenance operations by leveraging the network.
