74741 Datasheet, PDF (1/2 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, and its design allows
side-by-side stacking for increased density.
Features and Benefits
■ 1000Base-T compliant module meets IEEE802.3z,
ab, u specifications and is SFP MSA compliant
■ Less than 1 Watt power requirement provides low
heat output
■ Zinc backshells provide improved EMI
performance
■ Auto-negotiation feature allows networking
equipment to automatically determine and adjust
to the required settings
■ Automatic MDI crossover eliminates the need for
crossover cables or cross-wired (MDIX) ports
■ Bail latch provides ease of extraction
