The product is an Opton direct attach cable, 5 meters long. It is a copper cable (AWG24) with terminated modules that can be used with SFP and SFP+ ports. It is an ideal solution for connecting devices in a rack or server room. The maximum transfer speed is 10 Gb/s. The modules are programmable; however, they do not have A2 memory, so they cannot be programmed for devices that use this memory, such as the Cisco Nexus series.
