DAC Direct Attach Copper Cables are further divided into passive copper cable and active copper cableIn 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.SEESUO 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 the DACs are compatible with different brands on the original switches and routers.

Feature:

● Lower Power Consumption

● Compliant with SFF-8431 MSA

● Replace optical transceiver for short distance

● Active DAC can reach up to 15m

Applications:

● 10G~100G Ethernet

● Fibre channel

● Data center and in-rack connection

Direct Attach Copper (DAC) Cable

Volex is a leading manufacturer and supplier of Direct Attach Copper (DAC) cable. The Volex DAC cable product family is comprised of cable assemblies with Small Form-factor Pluggable (SFP), Quad Small Form-factor Pluggable (QSFP) and Octal Small Form-factor Pluggable (OSFP) single and double density series modules. Volex offers a full line of active and passive direct attach copper cables from 10Gbps SFP+ to 800Gbps OSFP and QSFP-DD800 designed to meet the requirements of the most demanding data centres with industry leading quality and reliability.

Direct Attach Cable (DAC) is widely applied in storage, data, and high-performance computing connectivity. The DAC cables are used to connect one mobility access switch with another when forming a stack. FiberOnSale supplies various kinds of high speed interconnect DAC cable assemblies including 10G SFP+ Cables, 40G QSFP+ Cables, and 120G CXP Cables. All of these direct attach cables can meet the ever growing need to cost-effectively deliver more bandwidth, and they can be customized in different length to meet customers' requirements.

What is Direct Attach Copper (DAC) Cable?

Direct attach cables are factory terminated copper cable assemblies with SFP, QSFP and OSFP single and double density series pluggable modules.

Low cost and low power consumption with no heat produced and very high reliability make passive DAC the preferred choice for short distance (1-5M) data centre in-rack equipment interconnect application. Active DAC can preserve signal integrity with embedded retimer or redriver extending the reach up to 9M for inter-rack interconnect application. Active DAC also can be an option for cabling high density rack with thinner and more flexible cables.
