[Green] Colored 10G SFP+ DAC Cable - Twinax SFP Cable for Ubiquiti UniFi Devices, 0.3-Meter(1ft)

These work great with my Ubiquiti switches and Dell servers.

Unfortunately connecting UDM Pro to Unifi Gen 2 POE 24 port switch connected and reported 10G but ran speedtest and barely got 500mb. switched back to standard copper ports and back to 940mb. bummer

This works perfectly to connect my 2 Ubiquiti (UniFi) switches through the SFP port.

I incorrectly thought that a .5 meter cable would be .5 meters of flexible cable. This is not the case. Here are some dimensions. 20 end to end, complete length with SFPs 15 of cable between SFPs 12.5 of bendable cable

10G tek is my go to source for these cables. A+

Frees up a network port on the UBNT switch. Connects the 2 switches. The other port has a SFP to standard data port. Connects switches to my Security gateway. Nice and clean looking.

Much to my surprise, the SFP module works perfectly as an uplink interconnect between Araknis routers and Araknis Gigabit switches. This frees up one Ethernet port on the router and switch in my project, which is valuable. The price is excellent and the cable seems to be working perfectly. The Araknis SFP ports are Gigabit, and the cable supports 10Gbps, but the link works just fine.

thank you

Update: It turns out the original DAC I received was defective. The vendor reached out and resolved the issue quickly. The new cable performs as expected. 5 stars for a company that backs their product! ————————- Original review below: This 2 meter DAC cable presents “OEM” as the vendor. Legit 10GTek shows up as “10GTek”. I would be willing to look past this if it weren’t for the terrible network performance. This cable yields 60Mbps (out of the 10,000 rating) using iperf. I validated this result with Speedtest and Fast and got the same result. Swapping DAC cables with a legit 10GTek cable gives me the expected speeds 984 Mbps symmetrical to the Internet (AT&T GigaPower) and 9925 Mbps between switches using iperf. I hope this review helps you make an unbiased informed purchasing decision.

This is a no-nonsense 10G DAC cable, I say that because you plug it in and it works. I’ve tested this cable myself with Cisco (Router and switches), Netgear (Switches), Mikrotik (Router and switches), Broadcom (NIC) and Mellanox (NIC) devices and it just works. High marks for compatibility. I own many cables from 10Gtek and they all are like this green one. I got the green cables for color coding devices. I’m very happy with this cable.
