Instant EtherFast II Series When using fiber, the noise loss has to be calculated. Also, always use the same type of fiber connector (SC or ST) for your fiber cables. If you are using ST-type connectors and you introduce an SC-type connector module, an SC to ST converter has to be obtained, or the ST connector may be replaced by an SC Connector Note: Changing connectors should be done professionally, using the proper tools. If you have never worked with fiber cabling, seek the help of an experienced professional. The following table shows the distance limitation when connecting the Linksys Fiber modules: Distance (meters/ft) Cable type Module in Hub A Module in hub B 208/672 412/1330 (Half Duplex) Multi-Mode 62.5/125uM Fiber Optic Cable Multi-Mode 62.5/125uM Fiber Optic Cable EF2HSC or EF2HST, EF2HSC, EF2HST SC or ST Type 100BaseFX SC or ST Type Fiber Distance Extender Fiber Transceiver Module EF2HSC or EF2HST SC or ST Type Fiber Distance Extender EF2HSC, EF2HST SC or ST Type Fiber Distance Extender 10/100 Hubs The following illustration is an example of how to connect two rack-mountable EtherFast II 10/100 Hubs together using fiber optic cabling. Notice that both hubs are equipped with 100BaseFX 1-Port Distance Extender modules. The distance extender modules allow data to be sent up to 208 meters (672 feet).
