The 499NMS25102 (fiber optic, multi-mode) and 499NSS25102 (fiber optic, single-
mode) modules have three 10/100 MBit/s twisted pair ports (10/100 base-TX, RJ45
connectors) and two 100 MBit/s fiber optic ports (100 base-FX, duplex SC
connector). It is possible to connect up to three DTEs (data terminal equipment) or
other TP/TX network segments to the TP/TX ports using twisted pair cabling. Two
additional DTEs or optical network components can be connected to the fiber ports.
