We bought some of this LC duplex OM4 cables for 10G connection. Used it with the SFP-10G-SR transceivers and the 16ch CWDM mux/demux, and the transmission speed is very pleasing. Loss of the cable is is within rather low values. I am very pleased with the performance of this high density cable.
You know when you need to upgrade your network to higher data rates you need not only high performance transceiver modules, reliable cables are also vital to successful installation. These quality LC-LC cables are exactly what needed to accomplish the whole process. They are more than useful but also helpful.
