Fiber Optic Network Connection
1. Remove the protective rubber covers from the fiber optic ports on the
applicable port on the module and from the ends of the SC connectors.
2. Insert the SC connector at one end of the fiber optic cable into the port
on the 2H28-08R. See Figure 3-6.
3. At the other end of the fiber optic cable, attach the SC connector to the
other device.
!
CAUTION
An odd number of crossovers (preferably one) must be
maintained between devices so that the transmit port of one
device is connected to the receive port of the other device and
vice versa.
If the fiber optic cable being used has SC style connectors that
do not resemble MIC style connectors, or has SC connectors
on one end and a different type on the other, such as ST
connectors, ensure that the proper crossover occurs.
NOTE
Leave the protective rubber covers in place when the
connectors are not in use to prevent contamination.
!
CAUTION
Do not touch the ends of the fiber optic strands, and do not let
the ends come in contact with dust, dirt, or other contaminants.
Contamination of the ends causes problems in data
transmissions. If the ends become contaminated, blow the
surfaces clean with a canned duster. A fiber port cleaning swab
saturated with optical-grade isopropyl alcohol may also be used
to clean the ends.
