QSFP-H40G-CU1M-RF

Cisco 40GBase-CR4 direct attach cable - 3.3 ft - beige

QSFP-H40G-CU1M-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 1-meter passive twinax copper cable connects QSFP+ ports on compatible Cisco Nexus, Catalyst, and UCS platforms for short-reach, low-latency rack and row interconnects.

This remanufactured direct-attach cable meets Cisco's original performance specifications and has been fully inspected and tested prior to shipment. Validation includes signal integrity verification across all four differential pairs, connector locking mechanism functionality, and end-to-end continuity testing at 40G line rate.

Key Features:
• 40GBASE-CR4 passive direct-attach copper (DAC) cable with QSFP+ connectors on both ends
• 1-meter cable length suited for top-of-rack and adjacent-rack switch-to-switch or switch-to-server connections
• Passive design requires no onboard signal processing, reducing power consumption compared to active cables
• Operates over four 10G differential copper lanes (4x10G) to deliver aggregate 40G throughput
• Cisco-coded EEPROM for plug-and-play compatibility with Cisco Nexus, Catalyst, and UCS platforms
• Compliant with IEEE 802.3ba 40GBASE-CR4 and SFF-8436 QSFP+ MSA standards
