APPLICATIONS

n Fibre Channel and Gigabit Ethernet

n Networking

n Storage

n Telecommunications

n Hubs, Switches, Routers, Servers,

Network Interface Cards (NICs)

The SFP+ stacked multi-port connectors with and

without light pipes are the latest additions to Molex’s

extensive SFP product line of connectors, cages and

patch cables. SFP+ takes SFP to the next level. SFP+

interconnects are designed to support applications for

8 Gbps Fibre Channel and 10 Gbps Gigabit Ethernet,

as compared to SFP, which is designed to support

2.125 Gbps Fibre Channel and 2.5 Gbps Gigabit

Ethernet applications. SFP+ interconnects use the same

space-per-port as standard SFP interconnects, therefore

providing 11.1 Gbps capability in a space that is 30%

smaller than XFP.

The SFP+ interconnect system supports the SFP+

speciﬁcations covering 6 different standards, which

deﬁne data rates ranging from 8.5 to 11.1 Gbps.

The SFP+ system is commonly referred to as 10

SFP+ (Small Form-factor Pluggable Plus) 10 Gbps Interconnect System from Molex supports

next-generation speeds of standard SFP applications, with a greater range of options for

increased port density

Gbps system although the speciﬁcation is rated up to

11.1 Gpbs. (See page 7 of product release for SFP+

standards and associated speeds).

SFP+ (SFF-8431 speciﬁcation) was developed under a

Multi-Source Agreement (MSA) by a group of diverse

companies to ensure industry-wide compatibility. The

SFP+ speciﬁcation addresses requirements for greater

power, reduced cost and smaller footprints than

existing 10 Gbps MSA’s (XENPAK, XPAK, X2 and XFP).

SFP+ industry standard requirements

n SMT design packaged in tape and reel to ensure

easy pick-and-place to the PCB

Upgrade to high-speed Ethernet and Fibre Channel ports with Molex’s SFP+ connectors

The SFP+ host connectors are a key component in Molex’s extensive SFP product line. Molex originally designed

the 74441 series to be capable of handling 10 Gbps data rates. With the launch of SFP+, Molex is well positioned

with a host connector that is tooled and in volume production.

The standard SFP host connectors offer excellent signal integrity at 10 Gbps. Thus, a customer using the standard

part does not need a board re-spin. Also offered is a new version with a modiﬁed housing to protect against a

mis-mated module. This offers the same electrical performance as the original host connector. The part numbers

for this version are 74441-5001 and -5010.

The connector is used in conjunction with single or ganged SFP+ cages (Series 74754).

SFP+ 20 Circuit Host Connector (Series 74441)

Features and Beneﬁts

n Available in 0.38 or 0.76μm (15 or 30μ”)

Gold (Au) plating, accommodating cost and

performance preferences

n Lubricated contacts available which are ideal for

extended life and harsh environment applications,

or applications that require telecom reliability levels

n Available in press-ﬁt, solder-post and PCI (1°)

versions to enable use with various board

thicknesses and assembly processes

n Optional rear and side-mounted lightpipe cover

assemblies allow for ﬂexibility of PCB signal routing

of LED’s

n Newly designed spring-ﬁnger gasket for single

cages provide optimal EMI grounding

Improved EMI performance and additional gasket options for SFP+

The SFP+ 1x ganged cages provide improved EMI shielding to the bezel by featuring an advanced 360°

elastomeric gasket design with multiple ground-pin locations for 10 Gbps Ethernet and 8 Gbps Fibre Channel

applications.

Spring-ﬁnger gasket versions are now available for the 1x ganged cages and for single-port cages. Single port

cages are available in press-ﬁt, solder-post and PCI (1°) versions with ganged cages available in a press-ﬁt

version. SFP+ cages offer customers a ﬂexible solution for use with various board thicknesses and assembly

processes at a lower applied cost.

The press-ﬁt tails accommodate belly-to-belly applications for both single and ganged cages to ensure the best use

of PCB real estate.

The cage is used in conjunction with the 20-circuit host connector (Series 74441).

SFP+ Single and Ganged Cages (Series 74754)

n Ganged cages have 360° elastomeric gaskets,

spring ﬁngers and multiple ground-pin locations for

advanced EMI shielding to the bezel

n Press-ﬁt tails accommodate belly-to-belly

applications for single and ganged cages to ensure

best use of PCB real estate

n Ganged cages available with up to 6 ports provide

multiple design options

lightpipes into one assembly to increase port density

and reduces assembly labor

Upgrade to 10 Gbps Ethernet and 8 Gbps Fibre Channel

ports with Molex’s Stacked Multi-Port SFP+ Connectors

The new SFP+ Stacked Multi-Port Connectors are the latest additions to Molex’s extensive Stacked SFP connector

product line. These high-port-density connectors offer complete integration of the connector within a cage and

include optional lightpipes to provide port-status indication to the user. These 25.50mm (1.004” height stacked

connectors provide two rows of belly-to-belly vertically stacked SFP+ ports. The SFP+ product line encompasses

connectors offered in six port conﬁgurations: 2-by-1,2-by-2,2-by-4,2-by-5,2-by-6 and 2-by-8.

Like the standard Stacked SFP connectors, SFP+ connectors feature compliant-pin tails for attachment to the PCB.

Application tooling is available for use with ﬂat-rock press methods. Tin/Lead press-ﬁt connector tails are provided

as the standard option. Tin-plated tails are also available to meet lead-free requirements. The footprint is the same

as the light pipe version of the standard Stacked SFP connectors. The footprint of the connectors with light pipes is

the same as the version without light pipes for each port conﬁguration.

Molex’s SFP+ Stacked Multi-Port Connectors accept SFP MSA-compliant modules, allowing installers to conﬁgure

and upgrade high-speed Ethernet and Fibre Channel (FC) ports.

SFP+ Stacked Multi-Port Connectors:

Metal Gasket (Series 76044, 76045, 76046, 76047, 76048)

Elastomeric Gasket (Series 76090, 76091, 76092, 76093, 76094)

Features and Beneﬁts

n Press-ﬁt termination to PCB eliminates soldering,

lowering the applied cost and avoiding solder-

related issues

n Modules oriented “belly-to-belly” when inserted

provides ease of removal of the module from

the port

n Copper cable data transmission to meet customer

requirements for speeds up to 10 Gbps and up to

25 meters

n Re-designed pull latch enables belly-to-belly cable

use and ensures highest possible port density

n Improved backshell design conforms to Small Form

Factor (SFF)-8431 speciﬁcations and provides the

highest quality design features to ensure trouble-

free operation

Connect 10 Gbps host systems with SFP+ Passive Cable Assemblies

at a much lower cost than optical cables

The superior electro magnetic interference (EMI) girdle design ensures the industry’s lowest EMI interference. Low

power helps to maximize the number of ports that can be used per host board. I2C (Inter-IC bus protocol) interface

and on-board EEPROM features enable the host to detect or conﬁgure speciﬁc performance characteristics.

Molex’s active SFP+ copper cable assemblies will incorporate optional active circuitry. The active assemblies will

require no additional special-driver circuitry than what is used for optical modules. The assemblies will also provide

loss of signal (LOS), transmit disable and offer a number of additional host- management capabilities.

SFP+ passive cable assemblies are designed to interconnect a variety of common physical-layer standards including

Gigabit Ethernet, Fibre Channel, Serial Attached SCSI, and InﬁniBand.

SFP+ Passive Cable Assembly (Series 74752)

n Identical mechanical dimensions as standard SFP,

enables backwards compatibility

n Available in passive and active designs to provide

system design ﬂexibility, minimize design

requirements in the host, enables “optical module”

performance, provides extended reach to 25 meters

and ensures an inexpensive 10 Gbps interconnect

n EMI girdle provides superior EMI performance for

up to 10 Gbps transmission
