Fiber-Optic Wiring	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.

Fiber Optic Connection Types

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.
