Arista CAB-SFP-SFP-5M Compatible 10G SFP+ DAC Cable 5m (16ft) Passive Direct Attach Copper Twinax Cable-HYTOPTODEVICE

The HYTOPTODEVICE CAB-SFP-SFP-5M (24AWG) sfp+10g dac cable is pre-programmed to be 100% recognized by Arista EOS as a native Arista cable:

• Arista 7050 Series: 7050TX, 7050SX, 7050QX (via QSA).

• Arista 7010 & 7020 Series: High-density 1G/10G access switches.

• Arista 7150 Series: Ultra-low latency platforms (7150S, 7150SC).

• Arista 7280 & 7300 Series: Deep-buffer and modular spine switches.

• Arista 7500 Series: Line cards with SFP+ interfaces.

• Operating Systems: Fully supported in Arista EOS. The cable is identified as CAB-SFP-SFP-5M, allowing for full Digital Diagnostic Monitoring (DDM) data and seamless port initialization.

The HYTOPTODEVICE CAB-SFP-SFP-5M 10g sfp+ to sfp+ dac cable is optimized for high-density Arista fabrics where reliability over distance is paramount:

• Low-Latency Leaf-Spine Architecture: Connecting Arista 7050X Leaf switches to 7300X Spine switches across multiple racks. The 24AWG core ensures the lowest possible latency without the overhead of active electronics.

• Cross-Rack Server Connectivity: Linking high-performance compute nodes to Top-of-Rack (ToR) Arista switches located up to 5 meters away. This is ideal for adjacent-rack spillover in modular data centers.

• HFT & Financial Trading Clusters: Providing a stable, 10Gbps physical layer for Arista 7150 series switches. The thicker 24AWG wire reduces jitter and signal noise, which is critical for time-sensitive trading data.

• Network Monitoring & TAP Aggregation: Connecting Arista DANZ (Data Analyzer) monitoring nodes to production switches across different cabinet rows.

FAQ for Arista CAB-SFP-SFP-5M Compatible 10G SFP+DAC Cable

Q1:Do I need a Passive or Active DAC cable? A:Passive DAC has no signal amplification, it is cheaper and its power consumption almost zero.it is ideal for short distance(up to 7 meters). Active DAC contains electronics to boost the signal.its power consumption is larger, it can transmit longer distance(up to 10 meters）

Q2:How far can I run a 10G SFP+DAC cable?A:Because DACs are made of twinaxial coppers, that are relatively heavy, and signal attenuation occurs more rapidly than in fiber optics. As a result, the practical transmission distance for 10G SFP+ DAC cable is limited to 7 to 10 meters.

Q3:What is the benefit of Passive DAC over Active Optical Cables (AOC)? A: Passive DAC and Active AOC can transmit data in short distance. With zero power consumption, higher reliability and lower cost, passive DAC has more advantages over AOC in short distance like 1 meter. 

Q4:How much power does it draw compared to 10GBASE-T (RJ45)?A:10G SFP+ DACs use copper cables, consuming only about 0.1W of power, whereas 10GBASE-T (RJ45) modules consume between 2.0W and 5.0W. Choosing DAC over RJ45 for short-distance transmission can reduce power consumption by more than 90%, significantly lowering heat generation and resulting in much lower procurement costs.

Q5:Does 10G DAC use Multi-mode or Single-mode fiber?A:Neither. The DAC(Direct-Attach Copper) is a copper cable. using a twinaxial copper architecture (Twinax) to transmit electrical signals directly, no light signals.There are not lasers or optical glass in DAC cable,  it is much cheaper than fiber optics.

Q6:Where to buy 10G SFP+DAC cable?A:There are many factories that produce and sell  passive DAC, but DAC manufacturer china HYTOPTODEVICE is the excellent provider: a source factory, fully controllable process, reliable performance, 100% compatible, sufficient inventory, fast delivery, and quick response.

Q7:Is 10G SFP+ to SFP+DAC hot-swappable?A:HYTOPTODEVICE SFP+10G DAC is hot-pluggable, hot Pluggable SFP+ Compliant.you can plug or unplug the passive DAC, while the device is powered on without damaging the hardware.

Q8:who makes the best SFP+DAC cable?A: Transceiver Manufacturer China HYTOPTODEVICE is the excellent provider.Sorce factory,reliable quality, 100% compatibiltiy.fast delivery and quick response.HYTOPTODEVICE send a tool that allows you to re-program the compatibility of your cables yourself.

Q9:What is the difference between 24AWG and 26AWG for a 5-meter Arista DAC？A: The main difference lies in signal integrity. 24 AWG cables have a larger cross-sectional area, which significantly reduces resistance. For a 5-meter SFP+ copper cable, the eye diagram of a 24 AWG cable is “clearer” than that of a 26 AWG cable, thereby providing better electromagnetic interference shielding and more stable performance in high-density, high-interference data center environments.

Q10:What is the difference between "Passive" and "Active" DAC?There are distinct differences between Passive and Active DAC.The Passive DAC has no signal amplification. its lengths is under 7m. With zero power consumptions,it cost is cheaper. The Active DAC contains a chip to boost the signal. Used for slightly longer copper runs (up to 10m-15m) and is generally thinner/more flexible.

Q12:Can I plug a 10G DAC into a 1G SFP port?A:No. SFP+ (10G) ports can often accept 1G transceivers, but a 1G SFP port cannot scale up to recognize a 10G DAC cable. You should Make sure the cable speed matches the port with the lowest rated speed.
