Huawei QSFP-40G-CU5M

Huawei QSFP-40G-CU5M Compatible 40G QSFP+ DAC Cable (5-meter, passive, QSFP+ to QSFP+, 26AWG). The HW QSFP-40G-CU5M Compatible 40G QSFP+ Passive Direct Attach Copper Twinax Cable is designed for use in 40GBASE Ethernet. It provides a QSFP+ to QSFP+ copper direct-attach solution. This cable is compliant with IEEE 802.3ba Ethernet standard and QSFP MSA Compliant.
With these features, this easy to install, high speed, cost-effective direct attach copper twinax cable is suitable for short-distance connectivity within a rack or between adjacent racks in data centres.

The DAC cable implements 4 independent 10.3125Gbps NRZ transmit and receive signal channels in each differential pair for an aggregate 41.25Gbps data rate. Standard length options cover from 0.5 meters to 7 meters. MSA memory map is accessible via 2-wire (TWI/I2C) interface. Our DACs are factory pre-programmed for compatibility, perform alternatively to genuine Huawei QSFP-40G-CU5M direct attach cables.

Note: FS Box does not currently support changing H3C and HPE compatibility for DAC cables.
