[j-nsp] experience using 10G DAC (twinax) cables between EX and multi-vendor

[Luca Salvatore]

We use the Juniper ones for connecting some dell SANs and HP 10Gb NICs into our EX4500s. Probably have over a hundred of them around the place... 
Never had any issues with them coming loose or anything else. For us, they have been a nice cheap alternative to going fibre.

We've had numerous twinax cables become dislodged enough to drop link not
only just by a minor bump, but all by themselves. Not even snapped out,
just going back and firmly pushing on the module brings it back. Totally
unreliable, at least the ones from juniper.

I got 10g sx modules for 85$ each. And they go much further, are easier to
deal with when you have hundreds of connections, can get custom lengths,
etc.

Enough persuasion yet? lol. Sorry for brief sentences, on my phone.
