Work as described. Thanks

work with Meraki

This little add on was a perfect setup for a network upgrade

Not sure if I got a faulty one or not but I’ve been running tests for an hour now and I can’t even get close to 1G speeds. On my computer it’s says it is connected at 10G but when I actually do anything it’s super slow . I even went down to only 1 meter and still terrible speeds. Speed test for example on a regular 1G Ethernet cable I can get 950Mbps but when I use the 10G TX i only get 325Mbps.

Outside of being put of stock when I need them most of the time they are amazing.

Bought a pair of 10Base-T transceivers for a pair of Ubiquiti switches with SFP+ ports. Have used 10GTeks fiber modules with no issues and speeds at the advertised 10Gb. The same is not true for these. Both switches reported the connection at 10,000FDX. The actual throughput was around 125Mb/s, no where near the advertised 10Gb. Pulled the transceivers and used the same Cat 6 cable on native 2.5Gb ports and immediately had speeds in the 2.5Gb range. Have used the same switches with Fiber transceivers which also advertised at 10,000FDX but had throughput to match. Side Note: these units run VERY hot, burning hot. Guessing that maybe the source of the slow speeds? Regardless, I didnt realize the speed issue until I was past the return window. Will try to get them warranted, possible I have a bad unit on one or both ends... UPDATE: Received partial refund from Amazon. TLDR 10Gtek transceivers incorrectly negotiated/forced 10Gb/s on cabling that could not support it. Non-TLDR Bought a pair Ubiquiti RJ45 10Gb/s transceivers to replace these. The Ubiquiti transceivers would only negotiate 1Gb/s FDX using the same cable run. Started researching why, discovered that the cat6 run was faulty and could not support 10Gb/s speeds. Replaced run with new Cat 7 run and the Ubiquiti transceivers connected and had throughput at 10Gb/s. Lesson learned, 10Gtek transceivers were falsely claiming 10Gb/s link when cabling could not support it. That complicates the troubleshooting process immensely and feels disingenuous.

I installed this product in a Cisco C3750X-48P switch with module C3KX-NM-10G with no issues.

Product works perfectly. Used it to connect from Cisco Catalyst 4500X to iSCSI SAN. I also received this T-Shirt from 10GTek after contacting their customer support with some questions that they happily and timely answered.

Product was as advertised and arrived quickly. Was installed in a Cisco 4500 switch and worked as expected.
