10Gtek SFP+ DAC Twinax Cable - 10GBASE-CU Passive Direct Attach Copper SFP Cable for Cisco SFP-H10GB-CU2M, Ubiquiti UniFi UC-DAC-SFP+, Meraki, Fortinet, D-Link, 2-Meter(6.6ft) | 0.25-12m Optional

Simple install, just plug it in and it works. I've always had great results with 10Gtek. 0.25m is the perfect size for linking ports for direct stacked rack equipment (no space between). Using with a UDM pro Max and a Unifi switch.

Worked perfect linking my Ubiquiti Cloud Gateway Fiber to a Cisco WS-C3850-12X48U-L with the C3850-NM-2-10G module. Both devices negotiated 10G without issue. I original purchased a DAC from Ubiquiti but the Cisco switch would only negotiate 1G.

Works like a champ with everything I tried it, except an old HP/Aruba 2920 I use for out of band access. I tried allow-unsupported-transceiver , but still does not work. The switch sees the cable transciever, but it won't use it because of missing HP specific model numbers. Oh well.

Works with no heat output. This DAC replaced an sfp+ to RJ45 transceiver that ran incredibly hot. Passive DACs are the way to go when short runs are possible!

Had to return. I am new to these new fangled connections and simply bought the wiring size for my switches. The cable is well made. I purchased the correct cables from this sourse with no issues and we quality made and connected at my 2.5gbps speeds...

I used this to connect my Mokerlink 10GbE PoE switch to my router, a Banana Pi BPI-R4 running OpenWRT. Since the orientation of these units are close enough for this short cable (.25M), it was a clean install, but it is a very short cable. If I was to do it over, I'd get the next length up to have a little more flexibility. Installation was easy and the cable fit perfectly and has zero dropped packets. I would definitely buy again.

Perfect size, easy installation, quality cables and SFPs, no issues with compatibility or speed.

Used with Unifi gear - 10 GBps without problems
