Connectors U1 (transmitter) and U2 (receiver) on the 4100-6057 Fiber-Optic Media Card 
are used to connect 4100-6014 NICs across parts of a network.  
 
Note:  ST connectors with long strain relief boots are to be used with the fiber 
optic cable. 
 
Figure 6-10 shows how two network nodes are connected via fiber-optic cable.

Dual Fiber Optic Cable Connections. The standard fiber optic connection between 
network nodes uses two fiber optic cables, one for transmit, and the other for receive. 
This connection allows for optimum communications distance.  
 
The available communications distance is determined by the properties of the specific 
fiber cable used. Distances can be determined using the information and examples shown 
below in Table 6-3. 
 
Single Fiber Optic Cable Connections. For applications where a single fiber cable is 
available, or where use of a single cable is desired, using a model 4190-9010 
Bi-Directional Coupler at each node combines the separate transmit and receive signals 
into a single path (refer to the requirements list).  
 
This connection allows use of a single fiber cable, but it does reduce communications 
distance as indicated in the information and examples shown below in Table 6-4.
