INSTALLATION
3.7 Connect the Fiber Optic Cables
The two factors to consider when connecting the cables are the topology and the
transmission media used. The cards can be connected in several different topologies
depending on your application. See section 2.3 Topologies, for more detailed examples.
Fiber-optic Cable Precautions
CAUTION: Fiber-optic cables are made of glass and may break if crushed or bent in a
loop with less than a 2-inch radius.
Look at the cable ends closely before inserting them into the connector. If debris is
inserted into the transmitter/receiver connector, it may not be possible to clean the
connector out and could result in damage to the transmitter or receiver lens. Hair, dirt,
and dust can interfere with the light signal transmission.
Use an alcohol-based wipe to clean the cable ends.
For short wavelength modules, either 50 µm or 62.5 µm core diameter cable should be
used. For distances up to 125 meters, 62.5 µm core cable can be used, and for distances
up to 250 meters, 50 µm core cables are required. For distances greater than 250 meters
(up to 10 kilometers), long wavelength modules with 9 µm core cables must be used.
The optional fiber-optic cables may be shipped in a separate carton. Remove the rubber
boots on the fiber-optic transmitters and receivers as well as those on the fiber-optic
cables. Replace these rubber boots when cables are not in use or if the node must be
returned to the factory. Attach the fiber-optic cables to the connectors on the GT200 card.
Figure 3-1 and Figure 3-2 depict the types of fiber-optic connectors needed for the
GT200 VME card.
