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
fibreoptic cable.
Figure 4-6 shows how two network nodes are connected via fibreoptic cable.

Dual Fiber Optic Cable Connections. The standard fibreoptic connection between
network nodes uses two fibreoptic 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
fibre cable used. Distances can be determined using the information and examples shown
below in Table 4-3.
Single Fibre Optic Cable Connections. For applications where a single fibre 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 fibre cable, but it does reduce communications
distance as indicated in the information and examples shown below in Table 4-4.
