Fiber Optic Design Considerations

Before fiber optic networks can be constructed, they must be properly designed and, once constructed, they must be managed. Efficiencies in these processes translate into lower cost layout and construction, more productive system migration and field operations, lower optical loss budget, and greater business profitability by bringing fiber to the desk.

The fiber optic network layout design plays an important role in error-free system reliability. Choice of the proper type of network layout depends on the type of process controlled, the possible need for expansion, and the degree of failure immunity desired–all of which must be balanced with cost considerations.

Basic Layout Network Designs

As is the case with electrical control system networks, four basic optical networks prevail: bus, star, ring, and collapsed backbone. For each type, the purpose of the network is to provide communication between the devices, or nodes, in the system. "Node" is a general term that refers to a programmable logic controller (PLC), remote input/output (I/O) drop, distributed control system (DCS) controller, or any communication device.

Network Layout Types

Each of the four network types has advantages and disadvantages, depending on the application. Historically, bus layouts have been preferred by PLC suppliers and star layouts by DCS suppliers–both on equipment OEM-configured for fiber optic signal transmission. Recently, both PLC and DCS suppliers have begun to offer more ring and collapsed backbone layouts than in the past.

Bus Network
In a bus network, all the nodes are attached in a line. This layout lends itself especially well to automobile assembly lines, lumber and paper mills, and other operations that begin with raw materials at one end, and end at the other end of a production line with a finished unit. The control devices are laid out in a linear array alongside the process machinery. Because the process machinery requires adequate clearances and right-of-way, it is usually easy to set up the cableways along the same right-of-way.

Star Network
The star network consists of a star (central) node device with arms extending out to other nodes. The star is used predominantly in facilities where different processes are physically separated, but must be centrally controlled, such as in petroleum refineries, chemical and pharmaceutical plants, and power-generating stations.

Ring Network
Devices in a ring layout are connected in a circular fashion. Each node is a repeater, and all nodes operate at the same speed under the same protocol. In theory, a simple ring handles complex processes but, in practice, relatively few processes lend themselves to a ring layout. A ring network can, however, be advantageous in high-reliability applications, because it can be installed in a modified self-healing configuration.

Collapsed Backbone Network
Today, networks are composed of broadband, baseband, and fiber cables. Broadband is the same type of cabling used by Cable TV companies, the cable carrying multiple channels. Baseband is the typical ethernet cable used to connect machines, usually known as thicknet or thinnet. Fiber, of course, is cable composed of glass fibers and the signals are transmitted as light. This composition of multiple media makes the network environment hard to manage and the transition to future technologies difficult.
