The TRANSITION Networks Ethernet™ 100BASE-TX to 100BASE-FX media converters
connect 100BASE-TX unshielded twisted pair cable to 100BASE-FX multimode OR
singlemode fiber-optic cable. Media converter models are selected according to the
fiber mode and fiber connector required at the site. Multimode fiber-optic cable can use
either an ST connector (E-100BTX-FRL-03) or an SC connector (E-100BTX-FRL-03(SC)).
Singlemode fiber (E-100BTX-FRL-03(SM)) uses only an SC connector. All media
converters function in half-duplex mode or, when connected to devices capable of full-
duplex connectivity, in full-duplex mode. An MDI/MDI-X switch allows straight-
through twisted-pair cable to be used for crossover 100BASE-TX connections.

CAUTION: RJ connectors are NOT INTENDED FOR CONNECTION TO THE
PUBLIC TELEPHONE NETWORK. Failure to observe this caution could result in
damage to the public telephone network.
