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

Features and Benefits

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).
