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

The Dream Machine Pro has two SFP+ 10Gbs ports I used them to uplink an old Ubiquiti US-24 Unifi Switch using one of the two native SFP ports, but also to uplink a newer Switch Pro 24 PoE that has 2x SFP+ 10Gbs ports. These cables allowed the auto-negotiation to work fine for each of the switches. I didnt have to fiddle with anything, other than re-classifying the UDM SFP+ WAN port to be just another LAN port. All is great right now.

worked for a short time of 2 months then failed... Update: CS is awesome! a replacement sent out. Communication through out the whole time. Good job and thanks Freya.

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.

Good quality cables, works great to direct connect a FC card from my ESX server to my QNAP NAS. Speeds are full 10Gb and no issues so far. Very happy with these cables.

plug and play. works as intended. link, link, aggregate. up comes the 20 Gig connection. If you think that youll like one, grab a second.

These work between a Ubiquiti X16 10Gb switch and various adapters. Including the FreeNAS expansion cards and Dell cards that came with several of our servers. No problems so far.

I like these cables because they are more durable than fiber cables and I have switched over to these DAC cables going from my two servers to the 10gb switches and all have worked flawlessly and these DAC cables come with the SFP+ modules included

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.

Works great with UDM Pro and poe switch second generation

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