5.5 Connect the Cables
5.5.1 Transmission Media
For short wavelength laser modules, either a 50 µm or 62.5 µm core diameter cable should be
used. For distances up to 300 meters 62.5 µm can be used. 50 µm cable allows distances up to
500 meters.
5.5.2 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 2.4, Topologies, for 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 laser modules, either a 50 µm or 62.5 µm core diameter cable should be
used. For distances up to 300 meters 62.5 µm can be used. 50 µm cable allows distances up to
500 meters.
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 the ones 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 SL240 PCIe card.
Figure 3-2 and Figure 3-3 depict the types of fiber-optic connectors needed for the SL240 PCIe
card.
