Fiber Optic Ethernet Ports
Fiber optic Ethernet ports are available with either MTRJ (Mechanical Transfer
Registered Jack), LC (Lucent Connector) or ST (Straight Tip) connectors. Make sure
the Transmit (Tx) and Receive (Rx) connections of each port are properly connected
and matched to establish a proper link.
