Linksys EFAH24, EFAH16W, EFAH08W, EFAH05W manual Cable type Module in Hub a Module in hub B 16/50

A maximum of 2 Transceivers can be connected together in one segment. When two hubs are connected via Transceivers together, the same rule of cascading two 100Mb hubs applies to them. To cascade another hub to these two hubs (using RJ-45), a switch or repeater must be used.

The Distance Extender is a switched port. This means another 100Mb hub can be cascaded (with RJ-45) to the hub that has a Distance Extender Module installed. Two Distance Extender modules can be connected togeth- er only at Half Duplex. Do NOT set either or both of the Distance Extender modules to Full Duplex. The Auto-Sensing hubs will not commu- nicate at Full Duplex.

When using fiber the noise loss has to be calculated. Also, use the same type of fiber connector (SC or ST) for you 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 has to be done professionally and proper tools have to be used. If you have never worked with fiber cabling, seek the help of a professional who is familiar with the medium).

The following table shows the distance limitation when connecting the Linksys Fiber modules:
