3.4.3Connecting a Fiber Optic Segment to the FE-100FX and FE-100F3

The FE-100FX and FE-100F3 have SC style network ports (see

Figure 3-11). Cabletron Systems supplies fiber optic cable that uses SC style connectors, which are keyed to ensure proper crossover of the transmit and receive fibers.

NOTES

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 crossing over occurs.

Fiber Optic Network Connection

1.Remove the protective plastic covers from the fiber optic ports on the applicable port on the module and from the ends of the connectors.

The FE-100F3 uses Class 1 lasers. Do not use optical

!instruments to view the laser output. The use of optical

CAUTION	instruments to view laser output increases eye hazard. When
	viewing the output optical port, power must be removed from
	the network adapter.

!

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 fiber optic ends.
