100G QSFP28 DAC cables - experience

Hi folks, I'm wondering if anyone have (either positive or negative) experience with 100G QSFP28 DAC cables? Is there anyone who is using 100G DAC in large scale and would recommend it (which means there are no issues compared to SR4 links)? I'm thinking about cables with lenght up to 1m, n

I doubt you're going to get a reply, but I will add this. Signal levels in that range are undoubtedly a local issue. Its either your drop, one of your splitters, or the tap on the pole. First thing I'd do is check with a neighbor thats on the same run and see what they say. That will pretty much

Re: 100G QSFP28 DAC cables - experience

We're using a mix as well, some QSFP28 AOC, others DAC. One thing that you need to keep in mind about the DACs is going to be the bend radius. These things are girthy af, so make sure to either overestimate your runs slightly, or buy one to test first. On Thu, Sep 14, 2017 at 11:54 AM, Hugo Slabbe
