TAILIEUCHUNG - Addressing High Density Fiber

Today’s optical distribution frame (ODF) systems are already required to handle more fiber than ever before, but as bandwidth requirements skyrocket, the need for even higher fiber density continues to increase. Manufacturers are scrambling to develop higher-density equipment and systems that can accommodate higher and higher numbers of terminations in smaller and smaller areas. | Addressing High Density Fiber Management Issues Addressing High Density Fiber Management Issues Today s optical distribution frame ODF systems are already required to handle more fiber than ever before but as bandwidth requirements skyrocket the need for even higher fiber density continues to increase. Manufacturers are scrambling to develop higher-density equipment and systems that can accommodate higher and higher numbers of terminations in smaller and smaller areas. While high termination density may require less floor space strong consideration must be given to the overall cost of such increased density. For example a higher-density ODF may not necessarily correspond to a higher fiber count potential in the central office CO . With many issues to consider the focus should be on developing a system with strong fiber cable management features. The key to the future is flexibility enough to accommodate future growth while enabling easy access to the installed fiber networks. This paper will cover unique challenges to ensuring high-density fiber cable management in homerun applications. It will detail the pros and cons of on-frame versus off-frame splicing craft access capabilities. Finally it will speak to what tools and equipment are necessary to ensure solid fiber management that allows flexibility for higher-density architectures. Homerun Applications Drive Density The fiber-to-the-premise FTTP architectures being deployed today fall into one of two categories active . homerun fiber or active star Ethernet or passive passive optical network or PON . There is also a PON homerun architecture that is prevalent among the independent operating companies IOCs . This architecture places all the splitters and WDM equipment in the CO located in the center of town to directly serve a relatively limited area. In this case high-density splitter solutions are an integral part of the distribution frame. Providers decide which architecture to use by weighing considerations
