<p>100BASE-FX connectivity for a port on 100BASE-TX Ethernet equipment is obtained by a fibre optic transceiver which is connected to a standard plug for a twisted pair connector and is also connected to signal detect inputs via the plug and thence by way of an isolating coupling to a logic circuit for switching the relevant physical layer device to the correct mode, (ie. either twisted pair mode or optical fibre mode).</p> |
