The 200G QSFP56 to QSFP56 Direct Attach Cable is a high-performance, cost-effective passive copper interconnect for LAN, HPC, and SAN environments. Supporting 4-channel full-duplex transmission at up to 28GBaud PAM4 per lane, it delivers a maximum aggregate data rate of 200Gb/s and meets or exceeds 200 Gigabit Ethernet and InfiniBand EDR/HDR performance and temperature requirements. The QSFP56 form factor conforms to SFF-8636 and is backward compatible with QSFP28 MSA, making it suitable for 40GE/100GE/200GE switch, router, and HBA deployments. Each cable carries a customizable EEPROM signature accessible via the I²C two-wire serial interface for asset tracking and vendor identification.
