Purchased a couple of different lengths for patching switches together. Cable works great! Links up at 1Gbps no problem, passes traffic without issue. Would highly reccomend to anyone that needs fiber cables.
Due to some shortsighted planning on my part needed a bunch of fiber for a EMC storage replication implementation happening the next day. Was a bit worried about not going with a "trusted" brand (in our case, someone like Carlisle Interconnect) - but didn't have time to go through those channels. Had problems establishing link on one of the cables - but swapping the GBIC cured it. Monoprice shipped quick, cables worked fine, and everything went as planned.
