DAC Cable 40g 3m

DAC Cable 40g 3m

40G QSFP+ Direct Attach Copper cable, length 3 meters, for 40G Ethernet aggregation and spine-leaf architectures in data centers. This passive copper cable has QSFP+ (Quad Small Form-factor Pluggable) connectors on both ends, each carrying four 10 Gbps lanes for a total of 40 Gbps (40GBASE-CR4). The cable uses twinax construction (typically 28 AWG) with EMI shielding. A breakout version (QSFP+ to 4x SFP+) is also available, allowing a single QSFP+ port to connect to four 10G SFP+ ports. The 3m length is suitable for in-rack and adjacent-rack connections. Passive DAC cables are low cost, low latency, and consume no power. The cable is compliant with IEEE 802.3ba (40GBASE-CR4) and QSFP+ MSA.
