10G SFP+ to SFP+ DAC Series

Description

● 10G SFP+ to SFP+ DAC:

DAC Direct Attach Copper Cables are further divided into passive copper cable and active copper cable. In most data center, most server to server connections require 2-5 meters, while rack to rack connections are required to be connected by 8-12 meters cables. Passive copper cable are widely chosen by data centers for connecting servers to servers or servers to the Top Of the Rack (TOR) switch as they are passive, consume zero power, have the lowest latency and cost-effective. Active copper cable is less expensive and can support transmission up to 15 meters with low power consumption, which can satisfies the regular interconnection requirement for distance and cooling in most data center. PancomLink offers a wide range of products for 0.5m to 15m lengths and in QSFP+, SFP+ form factors. The unique EEPROM technique has been used to ensure DACs compatible with different brands on the original switches and routers.

SFP+ DAC (Direct Attach Copper) passive twinax cable is suitable for very short distances transmission and offers a highly cost-effective and low power solution to connect within racks and across adjacent racks. SFP+ twinax passive cable allows for a serial data transmission up to 10.3Gb/s, which is a low cost choice for very short reach applications of 10GbE or 1-8G Fiber Channel. SFP+ DAC which replaces two optical modules and a connectorized optical fiber with a twinaxial copper cable assembly offers the higher density, lower cost, and lower power 10 Gigabit Ethernet solution than other cable types such as 10GBASE-CX4 and CAT6/CAT6A 10GBASE-T.

Active DAC design has a signal amplification and a class 10G Clock and Data Recovery(CDR) or Equalizer technology to support longer distances than standard passive SFP+ DAC cable.

AWG(American wire gauge), decreasing gauge numbers denote increasing wire diameters, the transmission will be more longer, 30AWG for 0.5~3 meters application, the price is better than 24AWG Cable.

Notice:
1. When link "Intel NIC" with over 3 meters SFP+ DAC Passive, you need to choose 24AWG, otherwise there will exist instability (1 or 2 meters, 30AWG is ok).
2. When link "Cisco switch" with 5 meters SFP+ DAC Passive, you could also choose 30AWG to save cost (because Cisco has enough compensation in the switch’s chipset ).
3. When link "Aruba (HP Provurve) switch", the hardware is different with others.
4. The compatible for "Brocade CNA", please choose the Active SFP+ DAC.
