It provides full duplex, parallel interconnects: 4 transmitting \/ 4 receiving data lanes and each lane at data rate up to 10.3125Gbps. Distance support could be up to 100 meters using OM3 fiber and 150 meters using OM4 fiber. Each lane could also be configured as independent 10G Ethernet transmission. Therefore facilitate higher port density at 10G Ethernet. Huihongfiber 40G QSFP+ SR4 is designed to meet the requirements of high speed, high density and low power consumption for applications in today\u2019s data centers.[\/vc_column_text][\/vc_column][vc_column width=&#8221;1\/2&#8243;
