Why Choose Passive SFP+ DAC Cable?

Passive SFP+ direct attach copper (DAC) cables, or SFP+ to SFP+ passive copper cables, are 10Gbps cables assembly. The cables are compliant with SFF-8431 specifications and provide connectivity between devices using SFP+ ports. And these cables use state-of-the-art signal processing technology to fill the expanding need for cost effective data center interconnects. Why would you choose passive SFP+ DAC cables? Information about passive SFP+ DAC cables will be offered in this article.

Overview

Passive SFP+ DAC cable assembly is fully compliant to the SFF-8431 SFP+ MSA. The cable construction is a 100 two pair shielded twinax with drain wires for digital ground. Passive SFP+ DAC cable allows for a serial data transmission up to 12Gbps in each direction. The passive design has no signal amplification in the cable assembly. Electronic Dispersion Compensation (EDC) is typically used on host board designs when passive copper cable assemblies are utilized. EDC allows for an extended length of passive cable assemblies. The mechanical design of the braid crimp and EMI skirt ensure that EMI radiation is sufficiently suppressed. Additionally, the copper cable acts as a natural heatsink. The low power consumption assists in making the passive copper cable assembly an economic solution for within rack or rack to rack applications. The following picture shows an HP J9281B compatible SFP+ to SFP+ passive copper cable.

Why Choose Passive SFP+ DAC Cables?

There are many solutions for 10G Ethernet applications. Why would you choose SFP+ to SFP+ passive copper cables? As the development of fiber technology, SFP+ to SFP+ passive copper cable still has its advantages in the market. Now, passive SFP+ DAC cables can support higher data rates than traditional copper interfaces. With the development of copper cable technology, passive SFP+ DAC cable is interchangeable and hot swappable with fiber optic modules. And most importantly, SFP+ to SFP+ passive copper cables are suitable for very short distances including 1m, 3m, 5m, 7m, 10m, etc. They offer a highly cost-effective way to connect within racks and across adjacent racks. SFP+ copper modules allow hardware manufactures to achieve high port density, configurability and utilization at a very low cast and reduced power budget.

Applications of Passive SFP+ DAC Cables

The SFP+ to SFP+ passive copper cable assembly meets 10 Gigabit Ethernet, Fiber Channel and other industry standard requirements for performance and reliability. They support multiple protocols such as Gigabit & 10G Ethernet, 1, 2, 4, 8, and 10G FC, Fibre Channel over Ethernet (FCoE) serial data transmission, and Infiniband SDR, DDR, and QDR. SFP+ to SFP+ passive copper cables are high performance I/O solutions for 10G Ethernet and 10G Fiber Channel applications.
