Cisco QSFP-H40G-CU2M Compatible 40GBASE-CR4 QSFP+ Passive Direct Attach Copper Cable 2 Meter, 30AWG
For use with data center cabling, direct connection between networking equipment, and other short distance, high bandwidth applications, the QSFP-40G-2M QSFP+ cable is a Cisco compatible QSFP-H40G-CU2M passive direct attach cable that supports 40 Gigabit Ethernet applications (The QSFP+ form factor supports 4 x 10G lanes for a maximum data rate of 40Gbps. Both the TX (transmit) and RX (receiver) support 4 channels). The direct attach cable is connected through QSFP+ ports (Quad Small Form Factor Pluggable) and is hot-pluggable.
Designed as an alternative to more costly fiber optic cables, these passive twinax cables are made for high speed, short length connections, and are fully compliant with MSA (Multi-Source Agreement) standards.
The Leapmicro QSFP-40G-2M is backed with a 2-year warranty for reliability and performance from PI Manufacturing.
