FEATURES AND SPECIFICATIONS

1000Base-T RJ-45 Gigabit

Ethernet SFP Copper

Transceiver

74741

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.
