Great cable for the price, wish it was the first shipment

The description states that it can operate at "up to 56 Gbps" when in fact it can only operate at up to 40 Gbps (http://www.mellanox.com/page /cables; MC2206130-003 may only work with FDR10, which is 40 GB/s) . Otherwise it's a decent cable. --- Update --- Just wanted to give an update after doing some more testing. These cables only marginally underperformed our AOC 56Gb/s cables, similar to 10Gtek 40G QSFP+ AOC for IBM/Mellanox Active Optical Cable, 3 meters. We achieved 22.8 Gb/s IPoIB with…

Pros
  • Direct Connect 40GbE QSFP+ to QSFP+ DAC Copper Twin Axial Cable with 3M Twin Axial Technology Passive 0.5 meter (1.64 ft) 30 AWG
Cons
  • Weight

Great alternative to Meraki QSFP cable

I have used 10g tek material on many installations. I recommend them to all my clients. They were used to install a pair of ms-225s in a wiring closet and they fit perfectly. A month later I have no problems. OEMs take great pride in their cables and charge a fee to put their name on them. 10g tek offers great cables at a great price.

Pros
  • 10Gtek is a direct attach copper cable manufacturer, custom service is available
Cons
  • Gotcha

Works great with Juniper switches

I bought a pair of these cables for use in my home lab. My company sent me a pair of EX3400 switches. Instead of spending tons of money on optics and cables, I decided to give them a try after being recommended on Reddit. I'm a CCNP R/S but my specialty is VoIP. So I'm not always up to date with factory connections from data centers. They worked like a charm and I was able to build a virtual chassis with little effort. I was able to share port channels between chassis. Everything works exactly…

Pros
  • We are 100% TDR and VNA tested in 10Gtek Signal Integrity Lab. And each DAC cable is individually tested on switches before delivery.
Cons
  • Something is wrong
