Cabletron Systems user manual Connect the fiber optic cable to the FOT-F3 as follows

CHAPTER 3: INSTALLATION

ST connectors attach to ST ports much like BNC connectors attach to BNC ports. See Figure 3-3. The connector is inserted into the port with an alignment key on the connector inserted into the alignment slot on the port. The connector is then turned to lock it down.

Caution: Do not touch the ends of the fiber optic strands and do not let ends come in contact with contaminants. Contamination of the ends causes problems in data transmissions. If the ends become contaminated, clean them with a soft, clean, lint-free cloth and alcohol.

Connect the fiber optic cable to the FOT-F3 as follows:

1.Remove the protective plastic covers from the fiber optic ports on the FOT-F3 and the ends of the connectors on each fiber strand. Save the covers and replace them on the connectors and ports whenever the fiber optic strands are removed from the FOT-F3.

2.Attach the fiber labeled 1 to the bottom port, labeledRX on the FOT-F3.

3.Attach the fiber labeled 2 to the top port, labeledTX.

4.At the other end of the fiber optic cable, attach the fiber labeled 1 to the transmit port of the device.

5.Attach the fiber labeled 2 to the receive port.
