MICRO SFP+ CONNECTOR & CABLE ASSEMBLY 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 additional 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.

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.

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 customer’s specific system architecture. WHAT WIRE GAUGE IS REQUIRED? TE offers micro SFP+ cable assemblies in wire gauges #26 other gauges on request to support customers’ 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. Longer 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, labeling and packaging, length, company logo, signal output de-emphasis, and signal output amplitude. We can custom engineer cables to specific customer system architecture.
