HiFiber 1-Pack 0.5m(1.6ft) 10G SFP+ DAC Direct Attach Copper Twinax Cable | 10GBASE-CU Passive, Compatible with Cisco,Ubiquiti UniFi,Netgear,TP-Link for Switch, NIC, Server and NAS

Works pretty with my UniFi system

Can confirm works fine with a range of unbranded unmanaged switches which Amazon sell such as YuanLey and Sodola, in fact I use one to connect those two brands together. Unable to test the max 10Gb throughput but likely hood is the switch itself will be the limiting factor before the cable. Use a few of these, cheap and do the job.

Used to connect two switches in a small rack, just worked,

I just needed short 10gb SFP+ DAC to connect my Ubiquiti Router, Switch and NAS together. These were perfect for the job and have been totally reliable. Highly recommended

I have bought these in multiple lengths. No issues in use with Ubiquiti networking equipment Length measurements include the DAC so allow for this if ordering very short cables 0.25m just allows a 1U to 1U connetion

Fantastic little Dac cable for the price and does what it says on the tin.

I used 10Gbit Passive DAC cables, direct from a switch to two two servers over 10Gbit, works well. Passive cables keeps the heat down as there are no SFP+ modules to power. The switch iteself gets warm to the touch, but not hot, it has no fan, so using these cables help. Switch is a Zyxel XMG1915-10E, servers are MinisForum MS-01.

Works great on Ubiquity system.

Perfetto..!! Utilizzato per collegare una Dream Machine Ubiquiti ad uno Switch Netgear GS 728 TPP. Si è connesso al primo colpo e funziona alla grande. Ottimo acquisto, di sicuro il sistema ne guadagna come velocità complessiva. Mi sento di consigliarlo ad occhi chiusi.

Detected immediately and runs at full speed without any issues ✔️ Negotiates at 10Gb instantly ✔️ Stable with no drops or errors ✔️ Perfect short length for clean setups ✔️ Solid build with tight, secure connectors ✔️ Works exactly like a proper SFP+ DAC should ⚠️ Connectors are very tight when removing I’m using this cable between my QNAP NAS and a switch, and it was recognized immediately. All devices report the link at 10Gb, and the connection has been completely stable with no drops or errors. I included a photo showing the interface registering at full speed. The 1 meter length is ideal for short runs between devices. It keeps the setup clean without extra slack, and the cable itself feels solid and well made. I don’t currently have another device that can fully saturate 10Gb for real-world throughput testing, but everything negotiates correctly and behaves exactly as expected. One thing to note is the connector fit. It is very tight, and the release tab takes a bit of effort. Not a problem, just something to be aware of. For a short SFP+ connection where you want something detected instantly and working without configuration, this cable has done exactly what I needed.

Comprado para conectar un NAS QNAP a un switch QNAP, en un entorno doméstico avanzado, este cable DAC pasivo SFP+ de 0,5 m cumple perfectamente su función. Fabricado en cobre Twinax, ofrece conexión full-duplex a 10 Gb/s estable y sin pérdidas. En mi caso, el cuello de botella lo impone el propio NAS (RAID5 de 4 HDD), no el enlace. 📊 Pruebas reales: Transferencias estables en torno a 990 MB/s – 1,1 GB/s medidos en Windows. Latencia muy baja y sin errores CRC en sesiones largas. Compatible al 100 % con módulos SFP+ del probado en gateway UniFi, switch y NAS QNAP. 🔧 Detalles físicos: Diámetro total del cable: 4,3 mm (medido con calibre digital). Construcción robusta, conectores metálicos con sujeción firme. Cable flexible y fácil de enrutar, aunque conviene mantener un radio mínimo de curvatura de 5 cm para no forzar el Twinax. 🔌 Conclusión: Excelente opción para enlaces cortos 10 GbE entre equipos en el mismo rack o escritorio. Muy baja latencia, buena disipación térmica y sin necesidad de transceptores ópticos. Recomendado al 100 % para interconexiones NAS-switch o servidor-switch.

After searching for a reliable DAC cable solution for our network upgrade, I decided to try these H!Fiber SFP+ cables, and I'm genuinely impressed with their performance. The pack of 2 cables offers excellent value for money, and the build quality is surprisingly good for the price point. Installation was straightforward - true plug-and-play functionality with no configuration needed. I'm using these between our Cisco switch and Ubiquiti equipment, and they were automatically recognized without any compatibility issues. The 1-meter length is perfect for rack-mounted equipment, and the cables are flexible enough for neat cable management without being too flimsy. Performance-wise, they deliver the promised 10Gb/s speeds consistently. I've been monitoring the connection stats, and there haven't been any packet losses or connectivity issues over the past three months of continuous operation. The passive design also means less power consumption and heat generation compared to active optical solutions. The build quality is solid - the connectors feel sturdy, and the latching mechanism works smoothly. The cable jacket seems durable enough for data center use, though I'd be careful not to bend it too sharply. Only minor criticism would be that the release tabs could be slightly larger for easier handling in tight spaces, but that's really nitpicking. For the price, these cables are an excellent alternative to more expensive branded options, especially when you need multiple connections in a budget-conscious setup. Highly recommended for anyone looking for reliable 10GbE connectivity. 4.5/5 stars

Good quality & well delivered
