H3C LSWM1STK 0.5m Compatible 10G SFP+ Passive Direct Attach Copper Twinax Cable

H3C LSWM1STK 0.5m Compatible 10G SFP+ Passive Direct Attach Copper Twinax Cable

This high-quality  H3C Networks Compatible SFP-10G-DAC, 10G SFP+ Passive DAC (Direct Attach Cable) Copper Twinax cable.  A cost-effective solution that provides high bandwidth and transmission rates over short distances. SFP+ Copper Twinax cables are suitable for very short distances and offer a highly cost-effective connection within racks and across adjacent racks. DAC cables offer a low-cost SFP+ solution. SFP+ directly attached Twinax cable assemblies supports 10 Gigabit Ethernet. Each direct attach cable is 100% optically inspected and tested for compatibility before shipping.

A direct attach cable, short for DAC cable, is a type of factory terminated twinax cable that connects directly into transceivers and can be brought in several lengths for short distances of up to 15 meters. These cables consist of fixed lengths of shielded copper coaxial or fiber optic cable with single pluggable transceivers at either end, that have varying gauge values between 24AWG and 30AWG. The direct attach cable may be capable of interconnection up to 15 meters using a twinaxial copper cable and reaches 100 meters over an active optical cable at 10Gbps, 40Gbps or higher.

DAC Cables can be either passive or active. The passive direct attach cable has no electrical components, which results in less power consumption. Active direct attach cables are composed of electrical components, so they use more power, but gain more distance and increase signal strength. Active cables are more expensive and consume more power when in use compared to passive cables.
