74737-0002 Datasheet, PDF (1/2 Pages) Molex Electronics Ltd. – RoHS Compliant 1-by-1 SFP Cage

FEATURES AND SPECIFICATIONS
Molex one piece 1-by-1 cages fully comply with all RoHS requirements
Small Form-factor Pluggable (SFP) RoHS compliant
cages are designed for Electro Magnetic Interference
(EMI) shielding of copper and optical pluggable
transceivers. These one-piece cages are stamped
and formed to meet the most current Multi-Source
Agreement (MSA) specification requirements.
Molex cages are designed with various pin options
to work with multiple board thicknesses and bezel
openings. The SFP system follows the function of the
standard Gigabit Interface Converter (GBIC) products
with reduced size and increased data transfer rates at
and beyond 2.5 Gbps.
Molex SFP products are multi-sourced, industry
standard products featuring a common design for use
with multiple data-transfer protocols. Protocols include
Fibre Channel, Gigabit Ethernet, and InfiniBand. Molex
provides a robust SFP solution with cable assemblies
(series 73929, 73930, 74742, 74743), adapters
(series 74720) and connectors (series 74441).
RoHS Compliant
1-by-1 SFP Cage
74737
Features and Benefits
■ Available in press-fit, solder post and PCI (1°)
versions enabling use with various board thicknesses
and assembly processes
■ Spring fingers with 2 points of contact offer optimal
EMI grounding
■ Optional rear-pin design for belly-to-belly
applications (Part No. 74737-0004) provides
additional PCB real estate with opposite board-side
usage
■ One-piece stamped and formed cage guarantees
cages are RoHS compliant by eliminating solder
■ Optional rear and side-mounted lightpipe cover
assemblies (Series 74726) available for all one-
piece RoHS SFP cages (Series 74737) allow for
flexibility of PCB signal routing of LEDs
