74741_04 Datasheet, PDF (1/4 Pages) Molex Electronics Ltd. – 1000Base-T RJ-45 Gigabit Ethernet SFP Copper Transceiver

FEATURES AND SPECIFICATIONS
The 1000Base-T RJ-45 Gigabit Ethernet SFP copper transceiver module is a high
performance integrated duplex data link for bi-directional communication over Category 5
copper cable. The hot pluggable feature allows changing to and from another SFP
compatible module without having to remove system power. Serial ID is included.
Molex's RJ-45 SFP module provides multiple customer friendly features. A link monitor
detects loss of signals. The Serial ID allows individual identification of each SFP
transceiver. An auto-power saving mode conserves energy. The centered RJ-45 modular
jack conforms to a 1U rack for ease of installation. Design allows stacking side by side for
increased density.
Features and Benefits
