The 100G QSFP28 to QSFP28 Direct Attach Copper Cable is a high-performance, cost-effective passive copper interconnect built for LAN, HPC, and SAN environments. Supporting 4-channel full-duplex transmission at 25.78Gb/s per lane, it delivers a 100Gb/s aggregate data rate and meets or exceeds 100 Gigabit Ethernet and InfiniBand EDR performance and temperature requirements. The QSFP28 form factor conforms to SFF-8665 and SFF-8436, ensuring reliable connectivity across QSFP-based switches, routers, and HBAs. Each cable carries a customizable EEPROM signature accessible via the I²C two-wire serial interface for asset tracking and vendor identification. Available in 1m, 2m, 3m, and 5m lengths with 26AWG to 30AWG wire gauge options, the cable balances signal integrity with cable flexibility for dense rack deployments.
