micro SFP+ Connector and Cable Assembly
TE Connectivity’s (TE) micro SFP+ connector and cable assembly empower you to dream big when
designing your communication system. Through a footprint that’s up to 50% smaller than current SFP+
interconnects, the micro SFP+ interconnects allow you to increase faceplate density while freeing up ad-
ditional PCB space due to the board connector’s shortened length. The products’ designs have also been
enhanced to improve signal routing, minimize EMI and optimize automated manufacturing processes.
• Increases Faceplate Density / Saves PCB Space: micro SFP+ is up to 50% smaller than current SFP+
connectors, in width and length, taking up as little as 15mm board space. One micro SFP+ frees up
19% more faceplate space than 1 SFP+ connector.
• Improves Signal Integrity: The cable assembly and connector were designed with a staggered
contact configuration that improves signal routing. Additionally, the bottom and top contacts have
been further optimized for speed.
• Reduces EMI: EMI is minimized through a die cast housing, cable shield crimped at 360 degrees, and
an extended EMI shield over the cable’s plug.
• Optimizes Manufacturing Processes: For manufacturing automation, the board interconnect
combines the connector & cage into one finished product for automated of board placement. High
temperature pin in paste soldering can be achieved as the product withstands up to 265 degrees
Celsius.

Micro SFP+ Cable Assembly Electrical Performance
WDP, VMA and VCR Measurements
Passive micro SFP+ Cable Assemblies : WDP, VMA and VCR Measurements
A passive copper cable assembly will be compliant with the SFP+ MSA Rev 4.1 if the dWDP number is
less than 6.75dBe. The WDP measurements shown in the table below are for the indicated wire gauge
and cable length of TE production assemblies. Any cable with the same wire gauge and shorter
length than the length listed below will have a lower dWDP value.
To be compliant with SFF 8431 Rev 4.1, the VMA must be less than 4.5 dB and the VCR must be
greater than 33 dB. The VMA and VCR measurements shown in the table below are for the indicated
wire gauge and cable length of TE production assemblies. Any cable with the same wire gauge and
shorter length than the length listed below will also meet the VMA and VCR limits.

Frequently Asked Questions
WHAT ARE THE PERFORMANCE REQUIREMENTS FOR THE CABLE ASSEMBLY?
TE micro SFP+ copper passive cable assemblies meet the signal integrity requirements defined by the
industry MSA SFF-8431. We can custom engineer cable assemblies to meet the requirements of a cus-
tomer’s specific system architecture.
WHAT WIRE GAUGE IS REQUIRED?
TE oers micro SFP+ cable assemblies in wire gauges #26 other gauges on request to support cus-
tomers’ specific cable routing requirements. Smaller wire gauges results in reduced weight, improved
airflow and a more flexible cable for ease of routing.
WHAT CABLE LENGTHS ARE REQUIRED?
Cable length and wire gauge are related to the performance characteristics of the cable assembly. Lon-
ger cable lengths require heavier wire gauge, while shorter cable lengths can utilize a smaller gauge
cable.
ARE THERE ANY SPECIAL CUSTOMER REQUIREMENTS?
Examples of special customer requirements include: custom cable lengths, EEPROM programming, la-
beling and packaging, length, company logo, signal output de-emphasis, and signal output amplitude.
We can custom engineer cables to specific customer system architecture.
