Inventory quantities are subject to availability and are not guaranteed until the order is placed.

The Cisco QSFP-H40G-CU1M is a 40GBASE-CR4 QSFP+ passive direct-attach copper (DAC) twinax cable with a 1-meter length, designed for high-speed 40 Gigabit Ethernet interconnects within a rack or between adjacent racks in data center environments. Using passive copper twinax construction, this cable delivers 40 Gbps of bandwidth with low latency and minimal power consumption, making it an ideal cost-effective alternative to optical transceivers for short-reach connectivity. QSFP+ connectors on both ends plug directly into compatible QSFP+ ports on Cisco switches, routers, and servers.

This remanufactured unit has been professionally inspected, tested, and restored to meet Cisco quality standards, delivering the same reliable performance as new. The cable is compliant with IEEE 802.3ba 40GBASE-CR4 and QSFP+ MSA SFF-8436 standards. Its hot-swappable design enables installation and replacement without powering down connected equipment, minimizing disruption to network operations.

Key Features:
• 40GBASE-CR4 passive direct-attach copper twinax cable, 1-meter length
• 40 Gbps bandwidth over copper with low latency and low power consumption
• QSFP+ to QSFP+ connectors for direct rack-to-rack or intra-rack connectivity
• Passive copper design — no optical components, no power required at cable level
• Hot-swappable for zero-downtime installation and replacement
• Compliant with IEEE 802.3ba 40GBASE-CR4 and QSFP+ MSA SFF-8436
• Ideal for data center top-of-rack switch-to-server and switch-to-switch connections

This cable is a cost-effective solution for high-density 40G connectivity in data centers and high-performance computing environments. By choosing remanufactured Cisco components, you are making an environmentally responsible decision while maintaining the performance and compatibility your network infrastructure demands.
