Fiber Optic Ethernet Ports
Fiber optic Ethernet ports are available with either MTRJ (Mechanical Transfer Registered Jack), LC (Lucent
Connector), SC (Standard or Subscriber 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.
