100BASE-FX Port
The 100BASE-FX port on the Catalyst 2940 8TF-S uses an MT-RJ connector, shown in Figure B-4. This
port uses 50/125- or 62.5/125-micron multimode fiber-optic cabling.
You can connect a 100BASE-FX port to an SC port on a target device by using one of the MT-RJ
fiber-optic patch cables listed in Table B-1. Use the Cisco part numbers in Table B-1 to order the patch
cables that you need.
