FEATURES AND SPECIFICATIONS
Customized and Standard Small Form-factor Pluggable (SFP) Multi-Port Stacked Cage Assemblies
with SlimStack Connectors Provide One-Piece Convenience and Superior Electrical Performance
These SFP Multi-Port Stacked Cage Assemblies from
Molex provide a simplified one-piece solution to meet
customer requirements for high-density SFP module
spacing. Available products support up to 4.25Gbps
data rates with power-filtering circuitry. Standard
versions feature an elastomeric gasket that reduces
insertion force into the I/O panel while ensuring a
reliable EMI seal. These assemblies feature the Molex
Board-to-Board SlimStack connector to maintain signal
transmission speeds and minimize costs. Circuit
components have been designed into the assemblies to
optimize electrical performance.
The product offering consists of standard and
customized assemblies, tailored to suit customers'
applications:
Standard Products - begin with two versions which
utilize two 1-by-4 SFP cages (series 73927) installed
belly-to-belly using one spacer board. The interface to
the host board is achieved with a 0.635mm (.025”)
SlimStack connector.
Styles include an original SFP-chassis style or a version
compliant with the ATCA* (Advanced Telecom
Computing Architecture) standard, the difference
specified by the height of the interface connector. The
ATCA version uses a 7.00mm (.276”) height while the
standard version uses a 10.00mm (.394”) height
connector.
Customized Products - include different configurations
of SFP cages, along with the addition of power filtering
components on the spacer board, customized
mechanical outlines or the options of pre-installed
LEDs and light pipes.
Features and Benefits
I Single-piece board-to-board assembly provides easy
installation and facilitates ordering and
inventorying of components
