QSFP-H40G-CU3M-RF

Cisco 40GBASE-CR4 Passive Copper Cable - 40GBase direct attach cable - 10 ft

QSFP-H40G-CU3M-RF is a professionally remanufactured Cisco 40GBASE-CR4 QSFP+ Passive Direct-Attach Copper Cable, designed to provide high-speed 40 Gigabit Ethernet connectivity between switches, routers, and servers in data center environments. This 3-meter cable supports short-reach, rack-to-rack and top-of-rack interconnects without requiring optical transceivers or external power for signal conversion.

This remanufactured direct-attach copper cable meets Cisco performance specifications and has been thoroughly inspected and tested prior to shipment. Validation includes continuity and signal integrity testing across all four lanes, connector locking mechanism inspection, and compatibility verification with Cisco Nexus and Catalyst platforms.

Key Features:
• 40GBASE-CR4 passive direct-attach copper (DAC) cable supporting 40 Gbps aggregate bandwidth
• QSFP+ connectors on both ends with integrated Cisco-coded EEPROM for plug-and-play compatibility
• 3-meter cable length, optimized for top-of-rack and end-of-row switch-to-server connections
• Four-lane 10 Gbps per lane (4x10G) architecture over twinaxial copper construction
• Passive design requires no additional power, reducing heat output and power consumption
• Compatible with Cisco Nexus 2000, 3000, 5000, 6000, 7000 series and select Catalyst platforms
