> 3 dayConnected two switches together with this cable and a pair of SFP+ modules. Then on the downstream switch, connected a PC with ethernet and RJ45 10Gbase-T module and the PC has a 10Gbase-T NIC (which is typically connected to the first switch in the same manner), and I know I can get constant 10gig speeds as a baseline. Data transfer (file copy) in the temporary setup to test out this fiber cable were slower than 10gig. Was more around 300MB/s (~2.5 gbps). Granted I cant rule out the fiber modules as the culprit, nor did I use any sort of fiber connection cleaner on the new cable. Ultimately, the cable works, but would I use it in my current setup? The answer would be no. Although, would certainly consider using it in a long run for 1gig downstream.

> 3 dayWas skeptical about the price of these cables at first but realized I got a great deal. Small server cluster was starting to show its age on gigabit Ethernet and was time for an upgrade. Some SFP+ 10GB Network Cards some transceivers and these cables and I was up and running besides having to configure my recently acquired NetApp Fiber Cluster Switch. These cables seem to be fairly durable being I have accidentally stepped on some a few times. Snagged two of them walking and I thought they broke. The LC connectors did snap off and snapped right back together. Now I know this is not normal use for a fiber optic cable but accidents did happen and the cables have been rugged enough to maintain their connection. Even with all the faults they still remained within a margin of error that each cable had on its own loss report. Yes every cable comes with a report on the label indicating its tested loss. I thought they were all the same label but no. Shows good quality control and indicates what you are receiving. Tested the cables with a borrowed meter and all tested within margin of error of what was specified. These specs maintained even after their mishaps.
