Connecting Fiber Optic ST-type, “twist-lock” 
  
 
The following procedure applies to installations using ST-type fiber connectors. 
This procedure applies to ports using multi-mode ST fiber connectors. 
1. 
Before connecting the fiber optic cable, remove the protective dust caps from the
 
tips of the fiber connectors.  Save these dust caps for future use. 
2. 
Wipe clean the ends of the dual connectors with a soft cloth or lint-free lens tissue 
dampened in alcohol.  Make certain the connectors are clean before connecting. 
Note: 
One strand of the duplex fiber optic cable is coded using color bands 
at regular intervals; you must use the color-coded strand on the associated 
ports at each end of the fiber optic segment
. 
3. 
Connect the Transmit (TX) port (light colored post) on the Magnum Fiber port to 
the Receive (RX) port of the remote device.  Begin with the color-coded strand of 
the cable for this first TX-to-RX connection. 
4. 
Connect the Receive (RX) port (dark colored post) to the Transmit (TX) port of the 
remote device. Use the non-color coded fiber strand for this. 
5. 
The LINK LED on the front of the fiber connector will illuminate when a proper 
connection has been established at both ends (and when power is ON in the unit). If 
LINK is not lit after cable connection, the normal cause is improper cable polarity.  
Swap the fiber cables at the fiber connector to remedy this situation.
