APPENDIX B

FE-100TX, FE-100FX AND FE-100F3

SPECIFICATIONS

The 6H122-08 supports three Fast Ethernet Interface Modules:

• FE-100TX

• FE-100FX

• FE-100F3

This appendix provides the specifications for these modules.

B.1

FE-100TX

The FE-100TX uses an RJ45 connector supporting Category 5

Unshielded Twisted Pair (UTP) cabling with an impedance between 85 and 111 ohms.

The slide switch on the FE-100TX determines the crossover status of the cable pairs. If the switch is on the X side, the pairs are internally crossed over. If the switch is on the = side, the pairs are not internally crossed over.

Figure B-1 shows the pinouts for the FE-100TX in both positions.

NOTE

The transmitter power levels and receive sensitivity levels listed are peak power levels after optical overshoot. A peak power meter must be used to correctly compare the values given above to those measured on any particular port. If power levels are being measured with an average power meter, add 3 dB to the measurement to compare the measured values to the values listed above.
