25G and 40G optics
SFP28 and QSFP+
25G to the server and 40G on uplinks is where a lot of fabrics sit, and the module count adds up quickly across a build.
We code, test, and label per link, and cut breakouts to the lengths the build actually needs.
Hardware shipped worldwide and crews dispatched from our Las Vegas warehouse.

Questions we get
SFP28 and QSFP+, answered straight
Can you supply breakouts to length?
Yes, cut and labeled per port map so the rack does not end up with loops of slack in the cable manager.
Do you test 25G modules?
Every one. Higher-speed modules are less forgiving, which makes bench testing more valuable, not less.
