10Gtek [Yellow Colored 10G SFP+ DAC Cable - Twinax SFP Cable for Ubiquiti UniFi Devices, 2-Meter(6.5ft)

Purchased to link two Mikrotik devices by SFP+. The connection seems solid and negotiates at 10G. Device is listed as “OEM” brand when connected. The cable appears well built and is solid. My only gripe is that the size listed of the cable includes the SFP terminals. I needed to span about one foot between the two devices so I purchased the .3M cable. Upon receipt I discovered the actual cable that would be usable was only 6” with the metal SFP terminals (normally inserted into the device and thus unusable length) is included in the listed length. I had to return for the longer cable to achieve an actual 1 foot run.

Got it to connect two switches by different manufacturers. Plug and play and go about your day. Shipped fast and packaged well enough. Would buy again next time I need another length. Like the color options so you can be subtle or bold, your choice

I use it between UDM pro and the Aggregation switch. They both negotiate at 10G

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.

Rating this at 3/5 due to 1/3 cables not working. They all worked for less than 2 months until it started dropping connections. Tried to get it resolved but the amount of time I spent with CC just to let them know that this one cable isn’t working and is dropping connections is way too long. Vendor did reach out to swap the cable after sending the defective cable in but that’ll result back n at least a week of downtime, which at this point it’s a lot easier buying another one instead.For a cable to stop working in less than two months, it’s not ideal. Yeah the price is affordable yet quality may be questionable at best. YMMV.

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.

I'm revising my original review. While the product I originally bought wasn't the correct part for my build, the support I got from 10G Tech was above and beyond! I was contacted by their support and after a few questions regarding my setup they shipped me a DAC that was a match for my system. I have no error messages from my Aruba switch. Thank you for the amazing support!Original review:While this DAC cable is a good value for the money...it doesn't work in my configuration. Unfortunately I'm outside my return window now. I have a UDM Pro and an Aruba 1930 POE switch. It connects at 10G, but has the switch in an alarm state of "non-compliant SFP inserted." Not sure what the long-term effects of running in this state would be.
