10Gtek# SFP+ DAC Twinax Cable, Passive, Compatible with Cisco SFP-H10GB-CU2M, Ubiquiti UniFi, Fortinet and More, 2 Meter(6.5ft) | 0.25-7m Optional

I used these to connect a Cisco switch and a Cambium Networks switch with no issues.

Works great with every piece of 10Gb equipment Ive use them on. QNAP NAS units, DLink 1510 Switch, HP Dual Port 10Gb NIC, and Connect-x2 NICs.

Ive bought several 10Gtek products, and as always, this cable is made from high-quality components and is well built -- it looks and feels like the wildly more expensive competitors version. Worth every penny. Anytime I need a special cable or network connection component, Im going straight to 10Gtek.

Works out of the box on my servers (intel NIC) and cisco switches

The cable is a genuine core,good conductive performance,not easy to heat,waterproof and anti-aging,use satisfaction.

The first cable I purchased from Twinax should have been about 1.5M and it definitely wasnt. It was definitely shorter. I returned that cable and exchanged it with a 2.5M cable. This cable was the right length but already were not off to a great start. This cable claims to work with Ubiquiti network switches and other network gear. I recently installed a TRENDnet 10 Gigabit PCIe SFP+ Network Adapter and originally thought after connecting this cable to it and to my 48 port 750W Ubiquiti switch that it might be the TRENDnet NIC. I thought it might be a faulty driver as the network connection kept dropping sometimes every few seconds. My suspicion that it was the cable came after I verified the NIC was connected into the PCIe slot correctly and re-seated the SFP+ cable. The connection was a bit more stable but still kept dropping connection every minute or so. I finally decided to purchase another SFP+ cable (Macroreer for Ubiquiti 10G SFP+ DAC 2m Direct Attach Copper Cable Passive (Blue)) Ive used this cable brand and type before to link my UDM Pro with my 48 port switch with absolutely zero issues. Now that the Macroreer cable is installed Ive had zero issues with connections dropping. I am now returning this cable from Twinax. I do not recommend this cable with a similar setup as mine.

Recently built a storage server for my video production company. I attached 2 editing bays to the storage server via 10Gtek SFP cabling. Read / Write performance has been stellar.

No difference in speed from the original Cisco part.

Does everything its supposed to. 10G speeds between 2 Mellanox SFP+ cards. Quality is up there with the best DAC cables, and i have no questions this cable will last for a very very long time.

I am very happy that I bought these cables.
