Linksys INSTANT ETHER FAST SERIES EFAH05W - Manual (Page 16)

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:
