QSFP-H40G-CU2M — QSFP+ 40 Gbps

The QSFP-H40G-CU2M from Cisco is a passive Direct Attach Cable (DAC) in QSFP+ form factor, providing 40 Gbps over 2 metres of pre-terminated twinax cable. This 2 m length positions it between the very short 0.5 m version and the 4 m version, typically covering connections between equipment located in adjacent racks. Its passive format ensures minimal latency and negligible power consumption. Thermal range: 0 to 70 °C.

Ideal for Top-of-Rack 40G links in data centres where servers and the access switch occupy two neighbouring racks, the QSFP-H40G-CU2M simplifies high-density cabling. No fibre, no conversion, reduced latency: infrastructure engineers adopt it for its operational qualities. Genuine Cisco hardware, manufacturer warranty.
