• Fiber backbone components must meet or exceed standard EIA/TIA 568-B (Electronic Industries Alliance/Telecommunications
Industry Association) for maximum power losses; single-mode fiber is preferred; attenuation should be measured at 1310 nm.
Figure 50 shows how two network nodes are connected via fiber-optic cable.
7.5.5 Dual Fiber Media Cards Fiber-Optic Connection Types (565-261, 566-376, 746-109 only)
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 in Table 12.
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 in Table 13.
7.5.6 4190-9010 Coupler Requirements
The 4190-9010 Coupler (271-012) is used with the 565-261 Fiber Optic Media Board (revision "C" or higher), the 566-376 or the 746-109.
It can not be used with the Duplex Fiber Media Cards (0566-1197, 0566-1198, 0566-1199, 0566-1200). Two 4190-9010 Bi-Directional
Couplers are required per connection, one at each node.
The 4190-9010 is equipped with type ST connectors. To make type ST to type ST connections, an ST to ST coupler, by others, is required. ST
to ST Couplers are available from:
• Black Box, part number FO200
• Fiber Instrument Sales, part number F1-8101
• Newark Electronics, part number 95F2097 (or the equivalent)
