Network Installation
Multipoint Transceivers
Multipoint transceivers can be used to eliminate the need for coaxial cable (which is easily affected by noise)
and replace it with transceiver cable as shown in the following diagram. This will increase overall system resis-
tance to noise.
Note Up to two sets of multipoint transceivers can be used in a network. The length of the network will be lim-
ited to the maximum length of transceiver cable.
Optical Ethernet Systems
Some manufacturers provide optical fiber components for Ethernet networks to provide high resistance to
noise. The following illustrations show some simple examples of optical installations. See the manufacturer for
specifics.
Use as Noise Countermeasure
The following illustration shows how optical components can be used to convert to optical fiber cable through
areas highly prone to noise.
