100Base-FX Fiber Ports
The 100Base-FX Fiber ports use SC connectors. Figure 2-7 shows an SC
fiber connector being inserted into a fiber port on the ELS100-24TXM.
Figure 2-7. Inserting an SC Fiber Connector into a Fiber Port
Depending on the fiber uplink module employed (see Table 2-3), these
ports support either multi-mode 62.5/125µm fiber or single-mode 9/
125µm fiber. The 100Base-FX ports use SC fiber connectors. The SC
fiber connectors are configured as a receive (RX)/transmit(TX) pair with
the RX connector positioned on the left side of the port and the TX
connector on the right side of the port.
