Quick Reference Guide SFP+ High Speed Copper Cable Assemblies Tyco Electronics SFP+ direct attach copper cable assemblies are a high speed, cost effective alternative to fiber optics in 10Gb Ethernet, 8Gb Fibre Channel and InfiniBand applications. SFP+ copper cable assemblies enable hardware OEMs and data center operators to achieve high port density and configurability at a low cost and reduced power requirement. Tyco Electronics SFP+ copper assemblies meet the industry MSA for signal integrity performance. FEATURES AND BENEFITS PRODUCT APPLICATIONS MSA SFF-8431 compliant Switches Supports serial data rates up to 10Gbps Networking servers, routers and hubs Low cost alternative to fiber optic assemblies Enterprise storage Low power consumption Telecommunication equipment Enhanced EMI suppression Network Interface Cards (NICs) Pull-to-release retractable pin latch APPLICATIONS BY PROTOCOL 24AWG through 30AWG cable available 10 Gigabit Ethernet and Gigabit Ethernet Passive and active assemblies (IEEE802.3ae) Uses MADISON CABLE brand TurboTwin Fibre channel: 1, 2, 4 and 8 GFC parallel pair cable InfiniBand standard SDR (2.5Gbps), DDR (5Gbps) and QDR (10Gbps) Fibre Channel over Ethernet (FCoE) Serial data transmission www.tycoelectronics.com/products/sfppluscaSFP+ High Speed Copper Cable Assemblies SFP+ Cable Assembly Part Number Selection Guide Minimum Maximum Base P/N Passive/Active Data Rate AWG Equalization Cable Length Cable Length 2127934 Passive 10Gbps 24 0.5m 7m UnEQ 2127933 Passive 10Gbps 26 0.5m 6m UnEQ 2127932 Passive 10Gbps 28 0.5m 5m UnEQ 2127931 Passive 10Gbps 30 0.5m 3m UnEQ 2032757 Active 10Gbps 24, 28, 30 0.5m 15m N/A SFP+ Cable Assembly : Specifications Connector Twin Axial Cable Interface PCB paddle card Operating Temp 0 to +70 deg C Impedance 100 10 Ohms Contact Material 30 Gold plated contact pads Storage Temp -40 to +80 deg C Jacket Material Flexible PVC Backshell Material Tin plated Zinc diecast Inner Shield Aluminum/Poly Tape 3x OD Static Bend Radius EMI Spring Tin plated copper alloy Outer Shield Tin Plated Copper Braid 5x OD Dynamic Latch Retractable pin UL Recognized 24AWG = 0.255 in Latch Release Molded thermoplastic pull tab CSA Certified 26AWG = 0.205 in Safety Certications Cable OD Retention Force 90N Max RoHS Compliant 28AWG = 0.185 in Durability 100 cycles Min REACH 2010 Compliant 30AWG = 0.170 in SFP+ Cable Assembly : Electrical Performance Passive 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 6.75 dBe. The WDP measurements shown in the table below are for the indicated wire gauge and cable length of Tyco Electronics 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 Tyco Electronics 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.
