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

It works exactly as expected. There is nothing else to say.

I have no idea what the lifespan is on some of this stuff, but 4 years is not it! Still going strong.

Seem to work 4. 4 stars because I havent used all of them. Got here fast.

Worked great for Intel x520 NIC. Came right up.

I purchased this item to connect my Ubiquiti UDM Pro to my Ubiquiti Gen2 Switch. Works like a champ.

Plugged it in between my UDM-Pro and my 8 port PoE switch. Instant high speed between the equipment and opened up a port.

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

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.

Running between the serve rrack and the distrbution panel. works perfectly fine

Was having problems with separate cables + transceivers (most likely the cable) - and when I switched to this integrated fiber SFP+ - xfers immediately jumped to expected levels.
