RamboCables SFP+ DAC Cable, (23ft/7m) 10G SFP+ Twinax Cable, Direct Attach Copper(DAC) Passive Cable, for Cisco SFP-H10GB-CU3M, Meraki,Ubiquiti UniFi and More, Length Options: 0.3m-7m

Didnt work by default, then I noticed that the connectors were crossed. They come with a numbered plastic label on each 1 & 2. One side was 1,2 the other was 2,1. I had to remove the connectors on one end from the clip holding them and reverse the cables. Then the interfaces came up as expected.

I have a Unifi UDM Pro and a Unifi USW Enterprise 8 switch with the Unifi SFP+ MM SR LC transceivers. Ive been using them with a Unifi OM3 cable to get 10 Gbps. I swapped the OM3 with this OM4 and everything worked the same. Got the full 10 Gbps. Connections were solid with the LC connectors. I have no reservations recommending this cable.

Quick delivery and worked perfectly

We used this to replace rodent damaged fiber. It’s heavier duty than the other cable. Works great.

Was skeptical about the price of these cables at first but realized I got a great deal. Small server cluster was starting to show its age on gigabit Ethernet and was time for an upgrade. Some SFP+ 10GB Network Cards some transceivers and these cables and I was up and running besides having to configure my recently acquired NetApp Fiber Cluster Switch. These cables seem to be fairly durable being I have accidentally stepped on some a few times. Snagged two of them walking and I thought they broke. The LC connectors did snap off and snapped right back together. Now I know this is not normal use for a fiber optic cable but accidents did happen and the cables have been rugged enough to maintain their connection. Even with all the faults they still remained within a margin of error that each cable had on its own loss report. Yes every cable comes with a report on the label indicating its tested loss. I thought they were all the same label but no. Shows good quality control and indicates what you are receiving. Tested the cables with a borrowed meter and all tested within margin of error of what was specified. These specs maintained even after their mishaps.

Worked perfectly and was a little longer than stated.

Connected two switches together with this cable and a pair of SFP+ modules. Then on the downstream switch, connected a PC with ethernet and RJ45 10Gbase-T module and the PC has a 10Gbase-T NIC (which is typically connected to the first switch in the same manner), and I know I can get constant 10gig speeds as a baseline. Data transfer (file copy) in the temporary setup to test out this fiber cable were slower than 10gig. Was more around 300MB/s (~2.5 gbps). Granted I cant rule out the fiber modules as the culprit, nor did I use any sort of fiber connection cleaner on the new cable. Ultimately, the cable works, but would I use it in my current setup? The answer would be no. Although, would certainly consider using it in a long run for 1gig downstream.

Very well made, faster than promised delivery, connectors scoped clean, great insertion loss. Overall great value for the money.

With a name like RamboCables how could this not be an awesome product? I ordered a shorter version for intra-rack connectivity, and the cable performs well. Its high quality construction gets almost all of the photons from point A to B effortlessly. What more could you ask?

as expected
