As fiber links support higher speed network bandwidths with increasingly stringent requirements, it is becoming all the more important to ensure that your backbone links meet tightening loss standards. The need for higher data transmission capacity continues to grow as network applications grow and expand. These higher transmission speeds demand cabling that delivers higher bandwidth support. This testing guide outlines cabling performance requirements, field testing, certification and troubleshooting techniques and instruments to ensure that the installed optical fiber cabling supports the high data rate applications such as 1 and 10 Gigabit per second (Gbps) Ethernet, Fibre Channel and the anticipated 40 and 100 Gbps Ethernet applications.
